In order to implement the Law of People's Republic of China (PRC) on the Prevention and Control of Air Pollution and prevent the pollution of cooking fume to the atmospheric environment and living environment, the State Environmental Protection Administration has formulated the emission standard of cooking fume. This standard has been implemented since 1 and 2002. The full text is as follows:
1 Subject content and scope of application
1. 1 subject content
This standard specifies the maximum allowable emission concentration of cooking fume in catering units and the minimum removal efficiency of cooking fume purification facilities.
1.2 Scope of application
1.2. 1 This standard is applicable to urban built-up areas.
1.2.2 this standard is applicable to the management of oil fume emission in existing catering units, as well as the design, environmental impact assessment, completion acceptance of environmental protection facilities and oil fume emission management in the operation process of new catering units; The internal staff canteens of food processing units and non-operating units that emit oil fume shall be implemented with reference to this standard.
1.2.3 This standard is not applicable to household oil fume emission.
2 reference standard
The clauses contained in the following standards constitute the clauses of this standard by reference in this standard:
GB 3095- 1996 ambient air quality standard
Gb/t16157-1996 sampling method for particulate matter and gaseous pollutants in exhaust gas from stationary pollution sources.
GB 14554- 1993 Emission Standard for Odor Pollutants
3 definition
This standard adopts the following definitions
3. 1 standard status
Refers to the state when the temperature is 273K and the pressure is 10 1325Pa. The concentration standard values specified in this standard are all dry flue gas values under standard conditions.
3.2 lampblack
Refers to oils, organic substances and their thermal decomposition or pyrolysis products volatilized in the process of cooking and processing food, collectively referred to as lampblack.
3.3 City
The definition of a city is the same as that in the Urban Planning Law of People's Republic of China (PRC), that is, municipalities, cities and towns established by the state in accordance with the administrative system.
3.4 catering units
All cooking stoves located in the same building and belonging to the same legal person are counted as a catering unit.
3.5 unorganized emissions
There is no oil fume emission from any oil fume purification facilities.
3.6 Oil fume removal efficiency
Refers to the percentage of oil fume removed after treatment by purification facilities and oil fume before purification.
P = (before C× before Q-after C× after Q)/(before C× before Q) × 100%
Where: p-oil fume removal efficiency,%;
C before-before the treatment facilities lampblack concentration, mg/m3;
Q—— Exhaust air volume before treatment facilities, m3/h;
C -- smoke concentration after treatment facilities, mg/m3;
