Problems solved by technology

[0002] At present, with the development of industry and the improvement of living standards, domestic waste and industrial waste are increasing. Even after treatment, a large amount of sludge is still formed, causing great pollution to the environment.
A better way to deal with it is to process the sludge into fertilizer. However, in the process of use, due to the large amount of metal ions remaining in the garbage, it is easy to be absorbed by crops. When people eat it, it will affect human health.

Abstract

The invention relates to a fertilizer using sludge as a main raw material, wherein the fertilizer comprises, by mass, 32-51% of a sludge fertilizer, 25-48% of sodium polyaspartate, and 2-8% of 40% pentachloronitrobenzene, wherein the sludge fertilizer is a sludge bio-organic fertilizer, can improve and promote the absorption of N, P and K by crops, the preparation method of the sludge fertilizer generally comprises: carrying out harmless treatment on domestic garbage in a sludge treatment plant, adding an additive and aerobic bacteria, and adding straw, corn cob and other crushed materials toprepare the sludge fertilizer, and the prepared sludge fertilizer has high organic matter content, and can improve soil.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a fertilizer with sludge as the main raw material. Background technique [0002] At present, with the development of industry and the improvement of living standards, domestic waste and industrial waste are increasing. Even after treatment, a large amount of sludge is still formed, causing great pollution to the environment. The better way to deal with it is to process the sludge into fertilizer. However, in the process of use, because there are many metal ions left in the garbage, it is easy to be absorbed by crops. When people eat it, it will affect people's health. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the invention provides a kind of fertilizer that takes sludge as main raw material, comprises sludge fertilizer, sodium polyaspartate and 40% pentachloronitrobenzene, by mass percentage, the amount of sludge fertiliz...
