Abstract

The invention relates to an organic composite fertilizer produced from house refuse and a production method thereof. The organic composite fertilizer is characterized by being prepared by using house refuse, pig excrement, chicken manure, fecal mud in a digestion tank, ground quick lime, calcium hydrophosphate, ammonium nitrate, potassium sulfate, sodium tetraborate, ferrous sulfate, magnesium sulfate and the like as raw materials and adopting the steps of mixing and stirring uniformly by adopting a double-shaft blade mixing and stirring machine and packaging. The organic composite fertilizer has various nutrients of nitrogen, phosphorus, potassium, trace elements and organic acids which can meet the growth requirement on the crops, has the advantages of no pollution, low cost and better benefit, prevents secondary pollution of the house refuse, protects the environment, saves the soil, and accords with the requirements for saving energy, reducing emission, protecting the environment and developing circular economy in China.

Description

technical field [0001] The present invention relates to an organic compound fertilizer produced from domestic garbage. Specifically, it is produced from domestic garbage through mechanical sorting, crushing, magnetic separation, high-temperature fermentation, disinfection and sterilization, and then drying, grinding and sorting. The organic compound fertilizer produced with powder, pig manure, chicken manure and septic tank sludge as the main raw materials belongs to the field of waste treatment. [0002] The invention also relates to a method for manufacturing the domestic garbage organic compound fertilizer. Background technique [0003] With the rapid development of my country's economy, the scale of cities continues to expand and the urban population is highly concentrated, people's consumption levels continue to increase, the amount of urban garbage generated is increasing, and the environmental pollution caused by domestic garbage is becoming more and more serious. Ur...
