Abstract

The invention discloses a sewage treatment device, which comprises a tank body, an anaerobic groove, an aerobic groove and a backflow pipe, wherein the anaerobic groove is formed between a water inletand a water outlet of the tank body; the backflow pipe is communicated with the bottom of the anaerobic groove and the top of the anaerobic groove. The device is designed by aiming at the rural sewage and the small-scale urban sewage; the anti-shock loading capability of the tank body structure is high; the structure is simple; the installation cost is low; the building period is short; the operation automation degree is high; the dismounting and regulation can be performed at any time according to requirements in different terrains; the use is flexible and convenient; the phosphorus-containing total concentration of the treated outlet water is lower than 0.2mg/L; the water body eutrophication influence is avoided.

Description

Technical field [0001] This application relates to the field of water conservancy, and in particular to a sewage treatment device. Background technique [0002] There are more than 600,000 administrative villages and more than 2.5 million natural villages in China, with nearly 800 million people living in them and their residences are relatively scattered. Due to insufficient infrastructure construction in my country’s villages and towns, most of the rural sewage is directly discharged into the surrounding water bodies without treatment, which seriously pollutes the surface and ground water bodies. At the same time, it also has certain impacts on the soil and the atmosphere, potentially endangering human, animal and plant life, health and safety. . However, because rural sewage is generally discharged in a combined system, the discharge is scattered and the discharge volume is small, and the sewage flow and organic load fluctuate greatly. The centralized treatment of rural sewage...
