Embodiment Construction

[0014] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings. The invention discloses a domestic sewage treatment system. The treatment system comprises a water inlet 3 connected to an external domestic sewage pipe and a water outlet 11 connected to an outward output pipeline of purified water after treatment. The water inlet 3 and the water outlet 11 are both Set on the same tank 14, the tank 14 is divided into two areas, the biological reaction area and the sedimentation area. At the bottom of the biological reaction area are the aerator 1 and the biological filler 2, which are transported into the tank 14 from the water inlet 3 After the domestic sewage is treated in the biological reaction area, it is transported to the sedimentation area, and the purified water after the sedimentation treatment is output from the water outlet 11. Regardless of whether there is at least one bioreaction area or pre...

Abstract

The invention relates to a domestic sewage treatment system which comprises a water inlet connected with a domestic sewage pipeline and a water outlet connected to a treated purified water delivery pipeline, wherein the water inlet and water outlet are respectively arranged on one tank body; the tank body is divided into a biological reaction region and a precipitation region; the bottom of the biological reaction region is provided with an aerator and a biological filler; domestic sewage fed into the tank body from the water inlet is treated by the biological reaction region and delivered into the precipitation region; and the purified water subjected to precipitation treatment is output outwards from the water outlet. The system well solves the problem of flowing of the sewage in one tank body, effectively saves the cost and reduces the occupied area.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated domestic sewage treatment system which can use microorganisms in water to purify water. Background technique [0002] In the prior art, the small-scale bioreactor adopts the multi-stage biological contact oxidation method, usually in multiple large independent glass fiber reinforced plastic tanks, and the sewage discharged into it is treated through the process of aerobic-clarification. The above-mentioned technology has the following defects: 1) The production investment of independent tanks connected by multiple pipelines is large. If one tank is used, the connection between different reaction areas becomes a difficult problem; 2) The application of a single filler is difficult to meet the requirements of modernization The need for biological sewage treatment. Contents of the invention [0003] The purpose of the present invention is to overcome the sh...
