Abstract

The invention specifically relates to a treating method for excrement in a poultry culturing farm, which belongs to the technical field of treatment of excrement in the poultry culturing farm. The objective of the invention is to provide a simple treating method for excrement in the poultry culturing farm. According to the method, excrement is directly subjected to fermentation and deodorization at a collecting place and then to drying to prepare organic fertilizer, and sewage is purified and then cyclically used; excrement, urine and other biological padding in a culturing room are collected together, and a decomposition additive and a deodorizing agent are added for treatment; and sewage obtained after flushing is purified and then cyclically used. The method provided by the invention is simple, does not need too many machines, saves cost and increases economic benefits; and resources are recycled, which meets requirements on current market and social development.

Description

technical field [0001] The invention relates to the technical field of manure treatment in farms, in particular to a method for treating manure in poultry farms. Background technique [0002] Farm wastewater contains poultry manure, residual feed, residual veterinary drugs, heavy metal ions, and pathogenic bacteria. The groundwater environment will destroy the sanitation of the rural environment. At present, the COD of aquaculture wastewater in my country has far exceeded the sum of the COD of industrial wastewater and domestic sewage discharge. In more than 14,000 large-scale farms across the country, 80% of the waste water is directly discharged into water bodies, while most of the waste water and feces of scattered farms (households) are directly discharged or piled up without any harmless treatment. Since most of the intensive farms are distributed in the densely populated eastern regions of my country and the rural areas near big cities, the harm is even more serious....
