Generally speaking, the application of quality management in projects has two aspects: project process and project products. Failure to meet either of these two aspects may have a significant impact on the products, customers and other interested parties of the project and the organization of the project. The following is my thesis on project management and project quality management for your reference.

On Project Management Project Quality Management Paper Mode 1: Denitrification Project Quality Management Assurance Strategy

The quality management of denitration project is a complicated work. Due to the huge investment of this project, once there is a quality problem, it will seriously affect the progress of the whole project. Therefore, it is very important to do a good job in the quality management of denitrification. In this paper, the denitration project in Yunning, Handan City is analyzed in detail, and the corresponding guarantee countermeasures for the quality management of denitration project are briefly analyzed.

Denitrification; Engineering project; quality management

1 Brief Introduction of Denitrification Project in Yunning, Handan

The project site is located in Yunning Power Plant, 2.5km north of Wu 'an City. Plan roads for parks around the site. The traffic is very convenient. The whole site is relatively flat and has good engineering geology. At present, there are three 240t/h circulating fluidized bed boilers. In order to make NOX in the flue gas discharged from three 240t/h circulating fluidized bed boilers reach the latest special emission limit of air pollutants in thermal power plants? According to the national standard 100mg/Nm3, it is decided to add a set of denitration device before flue gas emission to make NOX in flue gas meet the standard. This is the flue gas denitrification system of three 240t/h circulating fluidized bed boilers. Because the nitrogen oxides in the flue gas of the factory boiler exceed the new emission standard, it is necessary to denitrate. SNCR denitration process is selected, and the prepared urea solution or ammonia water is sprayed into the flue gas to meet the denitration requirements. According to the test data of nitrogen oxides in flue gas, the dosage of urea solution or ammonia water is automatically adjusted to realize automatic adjustment. The goal is to ensure the NOX content in the flue gas after denitrification.

Brief analysis of characteristics of NO _ 2 denitrification project

Denitrification project mainly refers to the construction task completed in accordance with fixed procedures in order to achieve fixed denitration capacity assets in a certain period of time, which mainly has the following characteristics:

2. 1 Time is clearly defined.

At this stage, because the country has issued ultra-low emission standards for air pollution prevention and control, and there is a time limit for implementation, the government has given strict regulations on the denitration project carried out by the factory, requiring that the denitration work must comply with national regulations. [1] For the newly designed denitration equipment, it is necessary to select nitrogen oxides below 100mg, which meet the super-body emission standards, so the construction period must be completed and put into use within the specified time. Therefore, the construction quality and time are limited, so the construction time of denitrification project is also very restrictive. [2]

2.2 High cost

Generally speaking, the unit cost of denitration projects on the market at present is very high, and because of the relatively large investment, many projects are paid in one lump sum during construction. In this way, the input cost is very high, so the control of the cost problem is even greater, which leads to the corresponding quality and safety issues are also highly valued. [3]

2.3 The engineering quality requirements are high.

Because the environmental protection requirements of denitration project are very high, the construction of denitration project must be carried out simultaneously with the boiler reconstruction of power plant. At this time, if the equipment quality is not up to standard, the whole power plant will stop, and the consequences will be very serious. In addition, due to the huge investment in denitration project construction, once the quality is unqualified, it will not only lead to huge economic losses, but also cause damage to the environment. Therefore, in the process of denitrification project construction, the quality must be strictly guaranteed. [4]

2.4 There are complete procedures.

The denitration project has a complete set of procedures during its operation. This feature requires that in the construction of specific projects, we should strictly do a good job of preparation and connection before and after operation. Moreover, in the process of project operation, it should be carried out in strict accordance with the fixed procedures of the project and cannot be tampered with at will. The main steps are: project feasibility study, project establishment, role, construction, trial operation and acceptance.

3 denitration project construction quality management problems

3. The influence of1on the quality of building materials

When denitration is carried out, the construction management of building engineering has a very important influence on the construction quality of denitration engineering. The effective management of engineering construction materials plays an important role in improving the quality of engineering construction. When denitration is carried out, the material cost of the project accounts for more than half of the whole project cost, but some enterprises only pay attention to the immediate economic benefits without scientific and reasonable management of the material cost of the project, so the material cost management of many projects is unqualified, thus affecting the quality of the whole project.

3.2 the influence of construction personnel

When denitration is carried out, relevant technicians play a huge role in the whole project, so the professional skills of construction personnel have a very important impact on the project quality. Only when these constructors have superb construction technology and professional skills can the project quality be guaranteed.

3.3 Influence of environment and other factors

With the continuous development of modern science and technology, mechanical equipment is more and more used in construction engineering. It can be said that the use of correct mechanical equipment in construction projects will also have a far-reaching impact on the construction quality of the whole project. Therefore, in the actual construction, we must use appropriate mechanical equipment according to the actual engineering situation. At present, during the development of denitration projects in some enterprises, related mechanical instruments and construction equipment are aging, which makes it difficult to keep up with the development of construction projects. In addition, the construction in some harsh environments has caused a series of quality problems in the quality management of denitration projects.

4 Effective countermeasures to ensure the quality of denitration project

4. 1 Establish an effective quality management system

The main goal of quality management of denitration project is to improve the overall quality of project construction, and bring together managers in different stages and positions to form a team with clear division of labor, coordination and clear responsibilities. As far as the construction of denitration project is concerned, from the initial design stage to the final construction scheme determination, from the procurement of raw materials to the final acceptance stage of the project, it must be strictly implemented in accordance with relevant implementation standards and construction specifications to form a perfect project quality management system. [5] In addition, in the specific implementation stage of the project, in addition to strictly observing the national and related industry norms, it is also necessary to formulate relevant enterprise implementation standards according to the specific nature of the project, and take this standard as the specific basis for construction. Through the above measures, not only can the quality problems of the project be effectively reduced, but also the progress of the project can be further strengthened.

4.2 Establish a quality responsibility system

In the process of denitration project quality management, the project manager can be said to be the organizer and leader of this project. Of course, he is also the first person in charge of this project, which plays a vital role in ensuring the quality problems in the construction process. Many practical work shows that a project manager's management level and quality awareness will directly affect the quality of the project. Therefore, if the project manager's quality awareness is weak, then various problems are likely to occur in the specific management process, which will inevitably affect the quality and progress of the project. [6] Therefore, in view of this situation, the project department of this project should establish a strict quality responsibility system for the project quality, and at the same time establish a corresponding assessment system, so as to make every working procedure and the use of every material in the project construction conform to the specifications. Moreover, the project leader should analyze each project in detail and summarize it in time, pay attention to the key problems and points in the construction process, and formulate relevant management measures that can be effectively used in the construction process. In addition, for some major engineering quality problems, we should personally stare at them until the problems are solved, while the general engineering quality problems need to be solved by the heads of relevant departments within a time limit. It is worth noting that the person in charge of the project department should analyze and deal with the engineering quality problems reflected by the construction personnel in time, find out the reasons for the engineering quality in time, and solve them as soon as possible in the construction process. In the process of construction, we should always communicate with construction professionals and often go to the site to investigate, so as to completely eliminate the worries of engineering quality problems.

4.3 Strictly check the acceptance items.

Generally speaking, in the quality management of denitration project, the acceptance of the project should be strictly checked. Specifically, there are the following points: First, we should have a deep understanding of the construction scheme. Before the project officially starts, the project leaders have a deep understanding of the construction scheme, and discuss the key and difficult problems that may be encountered in the construction process in time before the project starts, and get the best solution through discussion. In addition, for some professional and experienced personnel, arrange them in an important position in the whole construction, encourage them to play a key role in the construction, so as to ensure the engineering quality. Secondly, we must strictly purchase materials. Before the construction of the project, the relevant person in charge of the project department shall designate a special person to purchase qualified materials and inspect the purchased materials. Unqualified materials should be strictly controlled to prevent them from entering the construction site. Generally speaking, it is mainly to check the specifications, performance and suppliers of the main equipment and materials used. In addition, it is worth noting that when purchasing materials and equipment, we should pay attention to the selection of quality inspection personnel with a sense of responsibility and excellent professional quality, which will help to ensure the qualification of purchased raw materials and equipment. Finally, the key procedures in the project should be monitored. In the process of engineering construction, there are some important projects that need the attention of construction personnel and relevant responsible persons, such as automatic control system and circulating water treatment system. During the construction of these important subdivisional works, the responsible person concerned should send technicians with good professional quality and strong sense of responsibility to supervise in time to ensure the engineering quality.

Quality requirements of engineering project for 1 wireless network

1. 1 Specific characteristics of wireless network engineering construction

(1) The uniqueness of wireless network engineering construction. Any wireless network engineering construction, according to different geographical environment and user characteristics, has some unique features in function and use. In order to meet the needs of local users, it is necessary to establish wireless network engineering projects according to local specific conditions and related conditions. So from this perspective, the wireless network engineering project is unique.

(2) The variability of wireless network engineering construction. In the construction of wireless network engineering, many problems need to be solved, such as measuring the signal strength of each local position and the signal quality in different time periods, and the influence of various factors such as floor and signal interference on wireless network. This process takes a long time, and there will be many changes from planning to implementation, which will more or less affect the implementation plan of wireless network engineering projects, such as the resignation and replacement of personnel, the rise in material prices and so on. Therefore, the construction of wireless network engineering projects has the characteristics of variability.

(3) Diversity of wireless network engineering construction. Because the design of wireless network engineering projects needs the joint efforts of many aspects, there are many kinds of equipment and testing tools related to the engineering construction, which all reflect the diversity characteristics of wireless network engineering construction [1].

(4) The stage of wireless network engineering construction. As mentioned above, the construction of wireless network engineering projects takes a long time, so the management methods and quality requirements at different stages are different during the construction of wireless network engineering projects. Therefore, the construction of wireless network engineering projects has certain stages.

1.2 What are the quality requirements of wireless networks?

Regarding the quality requirements of wireless networks, this paper takes 3G wireless networks as an example to elaborate. First of all, 3G wireless network brings better experience to users in terms of speed, quality and function than 2G wireless network. But relatively speaking, 3G wireless network has higher requirements for engineering quality. 3G wireless network is very important for the quality of users' access to the network. To ensure the quality of user access to the network, it is necessary to ensure the stable operation of each base station [2]. On the other hand, 3G wireless network has many new functions and features compared with 2G, so it also has higher quality requirements in business services. Secondly, we all know that there are three major wireless network operators in our country. In order to increase their users, the three major operators, China Mobile, China Unicom and China Telecom, are trying their best to improve the speed and quality of their wireless networks. Because users mainly value the wireless network quality of major operators, the improvement of wireless network quality is also the main way to increase the user base; Finally, in the process of wireless network project construction, many reasons will interfere with wireless network communication, such as the quality of materials used in the project does not meet the requirements, and some operational details in the project construction do not meet the specifications and requirements. If these links are not handled properly, it will adversely affect the actual operation of wireless networks [3].

1.3 how to measure the signal quality of wireless network

There are different standards to measure the signal quality of wireless networks in different periods. In the process of wireless network engineering construction, whether the quality control is reasonable, whether the wireless network can run stably and the quality of the core network are all standards to measure the construction period of wireless network engineering. In the process of wireless network operation, the measurement standards will be different. In the process of operation, the main measurement standards are user satisfaction feedback and operators' own tests. Having a good quality measurement standard will have a very positive impact on the construction and development of wireless networks [4].

2 How to control the quality of wireless network engineering projects

2. 1 person as the main body in the process of controlling project quality.

Undoubtedly, talents are the main body and key to control the quality of wireless network engineering projects. To ensure the scientific and reasonable control of the quality of wireless network engineering, we must first ensure adequate and reasonable staffing, which is the basic premise to ensure the quality control of wireless network engineering reaches the standard. On the other hand, the relevant personnel of the wireless network engineering project should formulate specific engineering quality control requirements according to the local specific conditions of the project site, so that the wireless network engineering has rules to follow in quality control; Secondly, the quality of related equipment and equipment for quality control should also be strictly checked and controlled; Thirdly, before the construction of the wireless network project, we should fully investigate the local geographical conditions and other factors, formulate a construction plan that conforms to the local conditions, and ensure the smooth construction of the wireless network project; Finally, because the construction of wireless network project takes a long time, the price of materials needed for the project will change constantly. Procurement personnel related to the project must keep abreast of the changes in material prices to ensure that the quality of materials meets the standards. In view of the above aspects, we need to pay extra attention to the following aspects in the process of quality control of wireless network engineering: firstly, we need to ensure that the general person in charge of wireless network engineering projects has enough experience and technology, and at the same time, we need to be able to train and inspect subordinate employees to ensure that their technical level meets the requirements; Secondly, when selecting design companies and supervision companies, we should carefully inspect and select them to ensure that the company's capabilities and qualifications meet the requirements of network engineering projects; Finally, before the implementation of the wireless network project, it is necessary to formulate specific related contracts, determine the specific requirements of quality, and clarify the responsibilities of all parties [5].

2.2 Strengthen the supervision of network engineering.

(1) regularly supervise and detect network engineering projects. For the quality control of wireless network engineering projects, detection is an effective means and method. Using computer to test various parameters through specific software can fully understand the progress of network engineering projects. In order to ensure that the progress of the project meets the relevant quality requirements, it is necessary to carry out periodic cyclic testing to ensure that the parameters meet the standards. Relevant supervisors should supervise and test in strict accordance with the plan and quality requirements formulated by Party A, and through scientific and reasonable supervision and testing, some possible problems will be contained in the bud to ensure the quality of wireless network engineering projects meet the expected standards.

(2) Ensure the supervision authority of supervisors. If project supervision wants to play its due role and effect, it must be given the necessary supervision and management authority. In the process of wireless network engineering construction, related quality problems and technical requirements must be checked by the supervisor before they can continue. Review the relevant documents of each link of the project quality, and then review by the supervisor. The payment link related to the project should also be certified by the supervisor. Ensure the quality control requirements in detail [6].

3 Conclusion

Wireless network engineering projects are very strict in all aspects. Only by effectively grasping the engineering quality of each project link in network engineering construction can the overall quality of wireless network engineering be fundamentally improved. Therefore, it is particularly important to control the quality of wireless network engineering. This paper analyzes and studies the quality requirements of wireless network engineering project and the ways and methods of quality control, hoping to help wireless network engineering project improve the quality control effect, reduce the control cost and improve the quality of the whole wireless network engineering construction.
