Special excrement dry-wet separated wastewater irrigation system for pig farm

Abstract

The invention discloses a special excrement dry-wet separated wastewater irrigation system for a pig farm, and relates to the technical field of wastewater irrigation systems. A water pumping electricpump is arranged in a wastewater pool, one end of the water pumping electric pump is connected with a wastewater pump pipe, the wastewater pump pipe is connected with a centrifugal filter through a first connecting flange, a water inlet pressure gauge is arranged at the position, which is close to the centrifugal filter, of the wastewater pump pipe, the lower portion of the centrifugal filter isconnected with a discharging port, and a sand storage tank is arranged at the bottom of the discharging port. The system has the beneficial effects that the pig wastewater subjected to dry-wet separation is filtered through the device design of the system and then used for farmland irrigation, secondary filtration is adopted in the device to filter and clean impurities with large particles in thewastewater, the cleaned wastewater can be mixed with part of chemical fertilizers through a fertilization tank according to practical requirements of actual irrigation and is synchronously applied, sothat a better irrigation effect is achieved, the filtered wastewater can be directly irrigated and discharged, and the overall practicability is high.

Description

technical field [0001] The invention relates to the technical field of wastewater irrigation systems, in particular to a wastewater irrigation system specially used for pig farms after dry-wet separation of feces. Background technique [0002] With the vigorous development of the pig industry, how to deal with and comprehensively utilize pig manure has become a top priority in large-scale pig farms. If wet pig manure is not properly treated and comprehensively utilized, it will become a new environment. Pollution sources, feces and urine are directly discharged into rivers without treatment, and the pollution of land, air and water is becoming more and more serious. Liquid substances such as feces, urine and urine are good organic fertilizers after adding starters, bacteria agents, and fermentation. [0003] In real life, people have gradually begun to popularize the use of dry-wet separation device technology to process pig manure. The pig manure after dry-wet separation r...

AI Technical Summary

Problems solved by technology

[0003] In real life, people have gradually begun to popularize the use of dry-wet separation device technology to process pig manure. The pig manure after dry-wet separation reduces the content of COD and BOD in sewage, reduces the operating load of the biogas digester, and makes the biogas digester The active strains reproduce more vigorously, but the utilization rate of wastewater produced after dry-wet separation is poor. Generally, it is directly used for fertilizer irrigation without basic purification, which is easy to pollute the environment.
