2. All kinds of waste paper, such as various packaging boxes, papers, manuals, books, magazines, newspapers, etc. (Of course, you can also take it to the paper mill for recycling.)
3. Various fabrics, such as old clothes, towels, sheets, rags, etc. (Big enough to crush)
These can be sent to rural areas to allow farmers to accumulate fertilizer (you can organize village committees to build a big pit in a village, but pay attention to prevent leakage to avoid polluting underground water sources, and then spread this kind of thing layer by layer in the pit, which will become good fertilizer after three to five months, and then the villagers in each village will pull it to the ground to fertilize the crops themselves). There are several advantages: A, it relieves the pressure of urban garbage landfill at present, saves land B, improves the garbage recovery rate C, and reduces the money for farmers to buy chemical fertilizers (one reason for buying chemical fertilizers is that the accumulated chemical fertilizers are not enough for abel tamata, and the crops will grow faster); D, it helps to improve the soil structure and adjust the soil acid-base balance, so as to make crops yield high and farmers increase their income; E, it lays a good foundation for the promotion of green pollution-free food.
4. After the toilet sewage is physically filtered, the cleaner sewage can be discharged to the countryside to irrigate crops, and the thicker sewage can be sent to the countryside to accumulate fertilizer together with the kitchen waste mentioned above (farmers call human excrement the best fertilizer for crops).
5. Kitchen sewage and clean sewage (including washing, bathing, mopping the floor, etc. ) can be used directly (or filtered) to flush the toilet through the turnover station. Advantages: a, increased water utilization times and greatly saved drinking water resources; B, it is beneficial to improve soil structure and adjust soil acid-base balance; C, reduce farmers' money to buy chemical fertilizers, reduce farmers' money for irrigation, and save money for farmers; D, it is beneficial to crop growth and increase farmers' income; E, save groundwater, river water and other drinking water resources (because farmers use groundwater or river water to irrigate crops. Methods: A, every household, every street and every city should be equipped with two main drainage pipes, one for draining stool and flushing toilet water, and the other for draining kitchen and cleaning water. B, urban road rainwater can be discharged into rural irrigation through sewers. According to my preliminary calculation, urban kitchen sewage and clean sewage are enough to flush toilets. This method may need to transform the existing drainage system, but if there is no condition to transform it, all domestic sewage can be discharged to the countryside for irrigation, but we must observe the digestion situation in the countryside and not cause pollution in the countryside.
6. Industrial water is resolutely opposed to being discharged into rural areas, and relevant departments must manage it well. If the countryside is polluted, the consequences will be very serious!
