Intensive ecological treatment equipment for village and town sewage

Abstract

The invention discloses intensive ecological treatment equipment for village and town sewage. The equipment structurally comprises an aeration tank, a supporting plate, four aerators and a water outlet, wherein the supporting plate is transversely mounted at the inner center of the aeration tank; the four aerators are transversely arranged at the upper end of the supporting plate; the water outlet is located at the rear end of the aeration tank; the aeration tank comprises a water inlet, a dirt baffle, a filter screen, material collecting devices and a smashing device; each material collecting device comprises a filter material screen, a partition plate, a backflow preventing hole, a material separating block and a water through hole; the material separating block comprises a material clamping block, a material clamping groove, a guide plate and a rewinding spring; and the guide plate comprises a rotating hole, a downward flowing plate, a through hole and a clamping block. The two material collecting devices are arranged at the front end of the aeration tank to collect excrement mixed in water; and then the two partition plates are arranged in the material collecting devices, water flow gradually shrinks from upper end to lower end and flows downwards through the backflow preventing holes, so the situation that excrement at the lower ends of the partition plates flows back can be avoided.

Description

technical field [0001] The invention relates to the field of sewage ecology, in particular to an intensive village and town sewage ecological treatment equipment. Background technique [0002] Animal husbandry and agriculture are more common in villages and towns. The sewage discharged from animal husbandry and agriculture flows into the river, and follows the river to the nearby towns, which will affect the water safety of the towns. Therefore, it is necessary to use a Intensive village and town sewage ecological treatment equipment is used to treat the sewage flowing from villages and towns to cities, so as to ensure the safety of water for residents in cities and towns. During the purification process, sewage needs to enter the regulating tank, sedimentation tank, aeration tank, and disinfection tank. Only after treatment can the water source be used by residents. The sewage in villages and towns contains some poultry manure, and the manure will form biogas and diffuse in...

AI Technical Summary

Problems solved by technology

[0003] Based on the inventor's discovery above, the existing intensive village and town sewage ecological treatment equipment mainly has the following shortcomings, such as: when the sewage mixed with biogas passes through the aeration tank, because the sewage also contains part of the dissolved excrement , so that the feces debris enters the aerator following the flow of the water, and the water hole of the aerator is plugged, which shortens the distance of the water jet and makes the biogas in the sewage not in sufficient contact with the air, resulting in the waste mixed in the sewage Incomplete volatilization of biogas
