Underground rural sewage treatment device

Abstract

The invention relates to the technical field of rural sewage treatment, and discloses an underground rural sewage treatment device. The underground rural sewage treatment device comprises an enclosure, wherein the enclosure is embedded under the ground; a hydrolysis acidification tank is fixedly mounted at the bottom of an inner cavity of the enclosure; a reaction tank, an anaerobic tank, an anoxic tank, an aerobic tank, a precipitation tank and a disinfection tank are successively arranged on the right side of the hydrolytic acidification tank; the bottoms of the reaction tank, the anaerobictank, the anoxic tank, the aerobic tank, the precipitation tank and the disinfection tank are all fixedly connected with the bottom of the inner cavity of the enclosure. According to the underground rural sewage treatment device, a floor drain, a water collection box and a flow guide pipe are used for collecting rural ground surface sewage; a filtering pipe is used for conveying the ground surfacesewage into the hydrolysis acidification tank, so that the rural ground surface sewage can be conveniently collected and treated, and the pollution to the environment caused by free flowing of the ground surface sewage is avoided; the reaction tank, the anaerobic tank, the anoxic tank, the aerobic tank, the precipitation tank and the disinfection tank are used for jointly treating the sewage, andthe rural sewage treatment efficiency of the device can be favorably improved.

Description

technical field [0001] The invention relates to the technical field of rural sewage treatment, in particular to a buried rural sewage treatment equipment. Background technique [0002] Sewage, usually refers to polluted water from domestic and production discharges. Sewage mainly includes domestic sewage and industrial wastewater. The main pollutants of sewage include pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants, etc. . [0003] Domestic sewage is divided into urban sewage and rural sewage. The city has a high degree of automation and the sewage treatment effect is better, while the rural development is relatively slow. Most of the sewage is directly discharged into rivers and other waters. Rural sewage contains a large amount of pesticide residues, poultry and livestock manure etc. These pollutants lead to the existence of a large number of pathogens and toxic substances in the sewage. After flowing into the water area, it will cau...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an underground rural sewage treatment equipment, which has the advantages of efficient treatment of sewage, unique installation, and easy maintenance, and solves the problem of direct discharge of sewage into waters, causing large-scale water pollution , which seriously damages the natural environment. Ordinary buried sewage treatment devices generally adopt a fixed installation method, which is inconvenient to maintain and cannot effectively treat surface sewage.
