Description

A sewage treatment and discharge device for animal husbandry

technical field

The invention belongs to the technical field of sewage treatment equipment for animal husbandry, in particular to a sewage treatment and discharge device for animal husbandry.

Background technique

At present, the livestock and poultry breeding wastewater produced by most domestic farms is mostly wastewater such as washing pens. If the wastewater is directly discharged or washed into rivers, lakes and reservoirs with rainwater, it is easy to cause the water to turn black and smelly, and it will seep into the ground for a long time. As a result, the nitrate content in the groundwater increased, the water quality deteriorated, and the surrounding environment and groundwater of the farm were seriously polluted, threatening the health of residents near the farm. Therefore, it is necessary to use sewage treatment and discharge devices to purify the wastewater generated in the process of animal husbandry.

Although the existing sewage treatment and discharge device for livestock breeding can filter the sewage, the intercepted solids are discharged out of the discharge device, and the sieved sewage is sterilized by drugs and then discharged out of the discharge device, thereby realizing the treatment of sewage and emissions. However, in the existing sewage treatment and discharge devices, after the screening structure is easy to trap more solids, the solids intercepted by the screening structure are often cleaned through the flat push cleaning structure. Although the above flat push cleaning structure can Realize the cleaning of most of the solids retained by the sieve structure, but it is often impossible to effectively clean up some of the solid debris stuck in the sieve holes of the sieve structure, and it is easy to cause some solids to be pushed During the process, the sieve holes passing through the sieve structure fall into the sewage treatment chamber; in addition, with the prolongation of the working time, the solid matter clamped on the sieve mechanism will continue to increase, resulting in most of the sieve structure The sieve hole is blocked, which seriously affects the efficiency and effect of the device for subsequent sieve treatment of sewage.

For example, the invention with the authorized announcement number CN 209702450 U discloses a sewage discharge treatment device for livestock farms. If the solids are discharged through the discharge door and the waste slag discharge pipe, it is difficult to effectively clean the solids stuck on the filter layer during the discharge process, and it is easy to cause some solids to pass through. The sieve holes enter into the mixing chamber; and as time goes on, it is easy to affect the subsequent filtration effect and filtration efficiency of sewage, thereby affecting the treatment efficiency and treatment effect of sewage.
