Pig house capable of respectively collecting pig manure and pig urine and wash water

Abstract

The invention relates to a pig house capable of respectively collecting pig manure, pig urine and wash water. The pig house capable of respectively collecting the pig manure, the pig urine and the wash water comprises a pig house body, an automatic feeding device and a drinker, and is characterized in that a urine drainage ditch and a sewage drainage ditch are arranged on an outer side of the pig house body, wherein the sewage drainage ditch is arranged on an outer side of the urine drainage ditch. An excrement drainage platform is arranged on a corner of the pig house body, and an excrement accumulation pool is arranged outside a wall opposite to a side of the excrement drain platform. A urine drainage shallow ditch is arranged around the excrement drain platform, and the urine drainage shallow ditch is directly drained to the urine drainage ditch by a urine drainage guide pipe penetrating the wall or drained to the sewage drainage ditch by the urine drainage guide pipe penetrating the wall through see-saw type transfer bridge groove after the urine drainage shallow ditch is connected with a urine discharge ditch in abutted mode along the direction of the wall or a fence. A water drainage shallow ditch is arranged around the drinker and drained to the sewage drainage ditch by a water drainage guide pipe penetrating the wall and crossing the urine discharge ditch after the water drainage shallow ditch is connected with a water drainage ditch in abutted mode along the wall or the fence.

Description

technical field [0001] The invention relates to a pig house capable of separately collecting pig manure, pig urine and flushing water, which is a new approach for reducing pollutants in pig farms and belongs to the field of agricultural environmental protection. Background technique [0002] In recent years, large-scale centralized breeding of livestock and poultry has developed rapidly. At the same time, it has also brought about excessive concentration of livestock and poultry manure and a large increase in flushing sewage. Since most farms have failed to effectively treat and utilize livestock and poultry manure, The problem of livestock and poultry manure pollution has become increasingly prominent. According to the announcement of the first national survey of pollution sources, the national livestock and poultry breeding industry produced 243 million tons of feces and 163 million tons of urine. The discharge of major water pollutants: chemical oxygen demand 12.6826 mill...

AI Technical Summary

Problems solved by technology

[0010] The above patents all provide different technical means for reducing the discharge of excrement in farms. Among them, the method of leaking manure board can reduce the flushing water, but due to the need to increase the building height of the pig house and install the leaky manure board, it will increase the pig house. Construction costs, and the water content of the collected manure brings difficulties to the subsequent treatment; the use of fermentation bed pig raising technology can achieve the goal of emission reduction or even zero emission, but the high cost of litter also hinders the fermentation bed technology Further promotion and application of

In addition, none of the patented technologies mentioned methods and means for separating pig manure, urine and flushing water
