Abstract

The invention discloses a pig farm excrement treatment method and an additive. The method comprises the following steps of carrying out solid-liquid separation on pig farm excrement to obtain solid excrement and liquid excrement, adding calcium superphosphate or dicyandiamide into the solid excrement, and composting, adding dicyandiamide into the liquid excrement, and conducting then standing treatment, wherein the additive comprises calcium superphosphate and dicyandiamide, and the calcium superphosphate and the dicyandiamide are independently packaged. SSP or DCD is added into pigexcrement compost, degradation of organic matter can be accelerated, the content of total nitrogen and total phosphorus in a compost product is increased, the composting effect of SSP is good, and SSP can be used as nitrogen fertilizer organic fertilizer to be applied after composting; and dicyandiamide also has a good effect on resource utilization pretreatment of the liquid excrement.

Description

technical field [0001] The invention designs a farm manure treatment technology, and in particular relates to a pig farm manure treatment method and corresponding additives. Background technique [0002] In recent years, with the continuous development of the national economy and the increasing standardization and scale of the breeding industry, the feces of breeding enterprises have become an important source of environmental pollution in my country, causing a certain degree of damage to the surrounding environment and human health. influences. Due to the high cost of manure treatment, the lack of supporting land for breeding manure, and the imperfect environmental protection facilities, some farms often discharge part of the manure to the surface and water bodies without harmless treatment, which is harmful to the surrounding environment and soil. create pollution. Therefore, accelerating the harmless treatment and resource utilization of feces is of great significance to...
