How to deal with domestic garbage? Here, I would like to put forward my own shallow views:
75-80% of domestic garbage is organic matter. They are roots, leaves, stems and skins of vegetables, spoiled leftovers, leaves, waste paper, skins, dust, flowers and animals. Let's give these vegetables and grasses a name first. The remaining 20-25% are inorganic substances, including scrap iron, plastics, foam, glass bottles, and a small amount of wood, coal ash and broken electrical appliances.
Knowing the above ingredients, we can set up more trash cans (big mouth noodles) in the place where garbage is dumped now, and people can divide the above materials into several trash cans. Because garbage is a fresh commodity, it can only be treated by classification at that time. This is one of the key links, which can't be replaced by any machine. People have taken out the garbage like this since then, thus changing the habit of taking out the garbage. Only vegetables and grass are allowed to pour in the garbage passage on the high floors of the city. Other substances are much more concentrated and can be taken to the trash can below. Most of the inorganic substances in the trash can are only collected by the garbage collection station, and naturally someone picks them up, so the total amount of garbage is reduced by 15-20%. Most of the inorganic substances have been picked up. Therefore, a large number of vegetables and grass, which contain a lot of water, are transported by sanitation workers to factories with drying workshops, dried and then crushed in crushing workshops. This is farmyard manure (residue manure). This kind of fertilizer can be preserved for a long time, can be transported over a long distance, and can be compared with chemical fertilizer anytime and anywhere, which is very popular with farmers. The above drying and crushing process will form a waste treatment plant and a new industrial unit. Provide employment opportunities for laid-off workers. This kind of factory is required to be built around the city to reduce new environmental pollution.

With the development of urbanization, a large number of domestic wastes are concentrated, and the traditional treatment method of domestic wastes is direct landfill. Because the composition of domestic waste is uncertain and complex, and it contains a lot of organic matter and heavy metal substances, many non-degradable organic toxic substances will be synthesized when it is piled up for a long time, especially the content of dioxin is as high as 470~260ng/Nm3, equivalent to 9.4~5.2ngTEQ/Nm3. These non-degradable toxic substances will directly enter the atmosphere, penetrate into the ground through rain and snow, pollute the groundwater system, and cause serious pollution to the environment for a long time (100 will not degrade naturally), threatening human survival.
In view of the defects and existing problems in the current domestic waste landfill and incineration power generation technology, following the principle of circular economy and maximum utilization of energy, the technology and method with all independent intellectual property rights and national invention patents are adopted, which integrates bio-fertilizer separation and pretreatment, high-temperature secondary incineration power generation (complete decomposition and combustion of dioxins), brick slag production for building, and alkaline wet deacidification and dust removal, and realizes one-time comprehensive treatment of domestic waste and zero emission.
