With the development of the economy and the acceleration of urbanization, the urban population has proliferated and the city's pollutants are increasing. In fact, urban pollutants can be turned into organic fertilizer through treatment. Organic fertilizer is essential for organic agriculture and ecological agriculture. It can improve soil properties, improve soil fertility, increase the yield and quality of agricultural products, and curb environmental pollution. It is recommended that the government increase investment and design the classification and treatment of urban pollutants in the planning of urban construction, and use this as a new type of industry to treat urban pollutants into organic fertilizers with low prices and convenient transportation, turning waste into treasure for agricultural fertilizers.
Organic fertilizers are rich in organic matter and nutrients needed for crop growth. They not only provide the nutrients needed for crop growth, improve soil, but also improve crop quality, increase crop yield, promote high yield and stability of crops, maintain soil fertility, and increase fertilizer. Utilization, reducing production costs. The rational and rational use of organic fertilizer can increase crop yield, improve fertility, improve the quality of agricultural products, and improve the effectiveness of soil nutrients.
There are many raw materials for the production of organic fertilizers, which can be divided into the following categories:
1. Agricultural waste: such as straw, soybean meal, cotton aphid and so on.
2. Livestock and poultry manure: such as chicken manure, cattle and sheep horse dung, rabbit dung;
3. Industrial waste: such as distiller's grains, vinegar grains, cassava residue, sugar residue, furfural residue, etc.;
4. Domestic garbage: such as kitchen waste, etc.;
5. Urban sludge: such as river silt, sewer sludge and so on.
