[0002] The problem of environmental pollution caused by my country's pig industry is still serious. Many pig farms produce a large amount of sewage every day. The sewage from pig farms mainly includes pig urine, some pig manure, and pig house flushing water. It is a high-concentration organic wastewater and is suspended If this kind of sewage without any treatment enters the natural water...

Embodiment 1
[0028] figure 1 Schematically shows the flow of the farm manure treatment method according to one embodiment of the present invention.
[0029] refer to figure 1 , the farm manure treatment method, comprises the following steps:
[0030] 101: The manure enters the collection tank, and the manure in the collection tank is stirred and mixed.
[0031] Many farms produce a large amount of feces every day. The feces of the farms mainly include the urine of farmed animals, some feces and flushing water, etc., which belong to high-concentration organic wastewater, and are treated for the feces of the farms;
[0032] The collection tank has the functions of adjusting water volume and water quality to ensure the stable and continuous operation of subsequent facilities. At the same time, a stirring device is installed in the collection tank. Through stirring and mixing, the excrement in the collection tank can be adjusted and pre-reacted to increase the content of organic matter in th...

Abstract
The invention discloses a livestock farm excrement treatment method which comprises the following steps: conducting stirring and mixing in a collection tank, removing excrement and other suspended solids by a solid-liquid separator, feeding effluent of the solid-liquid separator into a black film biogas digester for anaerobic fermentation, feeding effluent of the black film biogas digester into amicroorganism selection pond for pretreatment, feeding effluent of the microorganism selection pond to a biochemical treatment pond for biochemical treatment, feeding effluent of the biochemical treatment pond to a biochemical sedimentation pond for mud-water separation, and feeding effluent of the biochemical sedimentation pond to a physicochemical reaction pond to enable suspended particles to form flocs, then conducting solid-liquid separation in an inclined tube sedimentation pond, conducting overoxidation disinfection on water obtained after solid-liquid separation, enabling the disinfected water to flow into a reuse water pond, and conduct direct discharge or further deep treatment on the water in the reuse water pond according to requirements. According to the present invention, thetreatment method has characteristics of reasonable design, effective treatment on degradation-resistant organic matter, high ammonia nitrogen and manure with severely-imbalanced C/N ratio can be achieved, the removal rate of organic matter and ammonia nitrogen can reach 90% or above, and environmental pollution can be effectively treated.
Description
technical field [0001] The invention relates to a method for treating farm manure. Background technique [0002] The problem of environmental pollution caused by my country's pig industry is still serious. Many pig farms produce a large amount of sewage every day. The sewage from pig farms mainly includes pig urine, some pig manure, and pig house flushing water. It is a high-concentration organic wastewater and is suspended If this kind of sewage without any treatment enters the natural water body, it will increase the content of suspended solids, organic matter and microorganisms in the natural water body, and change the physical characteristics, chemical characteristics and biological characteristics of the natural water body. If the sewage in the pig farm is not treated in time, it will cause great pollution to the environment. Contents of the invention [0003] The purpose of the invention is to provide a method for treating manure in farms. [0004] According to one a...
