Rural domestic sewage treatment system

Abstract

The invention relates to the field of sewage treatment, and discloses a rural domestic sewage treatment system, the rural domestic sewage treatment system comprises a liquid storage tank and a sewagedischarge pipe, wherein the liquid storage tank is an opening, a tank cover is opened at the opening of the liquid storage tank from the center to the two sides, the center of the tank cover is provided with a first sewage outlet, and the bottom center of the liquid storage tank is provided with a through hole; the liquid storage tank is provided with a centrifugal tank which is coaxial with a central axis, taper covers capable of being opened to two sides are arranged the opening of the centrifugal tank, the center of the taper cover is provided with a second sewage outlet, the centrifugal tank is introduced into the sewage discharge pipe through the first sewage outlet and the second sewage outlet, the centrifugal tank wall is provided with a centrifugal hole, the lower part of the through hole is provided with an electric motor, and the center of the bottom of the centrifugal tank is provided with a rotating mechanism. The rural domestic sewage treatment system can realize the purpose of solid-liquid separation of rural domestic sewage, the domestic sewage is subjected to solid-liquid separation and then treatment, the treated domestic sewage can be used for rural production demand, and the method effectively utilizes the products produced after domestic sewage treatment, and can be more useful for treating domestic sewage.

Description

Technical field [0001] The invention relates to the field of sewage treatment, in particular to a rural domestic sewage treatment system. Background technique [0002] At present, most rural areas do not have drainage channels and sewage treatment systems, and the sewage treatment rate is low. Most of the domestic sewage is discharged directly into the river or discharged into the outdoor open space and then arbitrarily infiltrates into the ground. A small part of it is simply treated in septic tanks and then infiltrates underground to seriously pollute the river water. , Affecting the living environment of villagers and potentially endangering the health of farmers. [0003] The sewage treatment system helps to purify rural domestic sewage and reduce the pollution of domestic sewage to rivers, lakes and groundwater. However, the existing rural domestic sewage treatment system cannot effectively separate and treat solid and liquid pollutants, causing both liquid and solid pollutan...

AI Technical Summary

Problems solved by technology

However, the existing rural domestic sewage treatment system cannot effectively separate and treat solid pollutants and liquid pollutants, causing both liquid pollutants and solid pollutants to flow into rivers and lakes, making rivers and lakes contain more silt and eutrophication Substances that pollute rivers are treated through solid-liquid separation, so that pollutants in solid and liquid states have appropriate places to go when they are discharged. The separated solid substances are treated and used to fertilize barren land, and the treated liquid substances are Used to irrigate the land and effectively recycle domestic sewage
