Problems solved by technology

[0008] At present, most rural areas in my country do not have complete sewage collection and treatment facilities. At present, most villages in my country do not have drainage channels and sewage treatment systems. A large amount of untreated sewage is directly discharged, causing great pollution to sewage and soil. , and will seriously threaten the safety of groundwater and the health of rural residents

Abstract

The invention discloses a biotechnology-based simple treatment device for rural sewage. The device comprises a treatment tank, a first partition wall is arranged at the rear side of the inner cavity of the treatment tank, the first partition wall divides the inner cavity of the treatment tank into a front cavity pool and a rear cavity pool, a second partition wall is arranged at the left side of the inner cavity of the front cavity pool, the second partition wall is uniformly provided with a plurality of buffer holes, the second partition wall divides the front cavity pool into a water inlet pool and a settling pool, a third partition wall and a fourth partition wall are arranged in the inner cavity of the rear cavity pool, and sequentially divide the rear cavity pool into an adsorption pool, a biological pool and a water outlet pool from the right to the left, and a three-layer terraced field is arranged in the biological pool. The layered progressive treatment of the sewage is achieved by arranging the settling pool, the adsorption pool and the biological pool, so the treatment effect of the sewage is greatly improved; the three-layer terraced field is arranged, and Iris pseudacorus L., Iris tectorum Maxim. and Acorus calamus L are used to biologically absorb the sewage, so the purpose of purifying the sewage is achieved; and the device has the advantages of utilization of rural characteristics, low input cost, and easiness in promotion.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a simple treatment device for rural sewage based on biotechnology. Background technique [0002] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage are pathogenic pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. [0003] From the viewpoint of the source of sewage, sewage can be defined as waste-carrying liquid or water discharged from residential, institutional, commercial or industrial areas mixed with groundwater, surface water, snowstorms, etc. There are many types of sewage, and correspondingly there are many technologies and processes to reduce the impact of sewage on the environment. According to the source of sewage, sewage can be divided into these four categories. [0004] The f...
