Sewage treatment device

Abstract

The invention provides a sewage treatment device. The sewage treatment device comprises a filtering tank and a treatment tank, wherein a water inlet pipe is arranged at the upper part of the filtering tank, and the lower part of the filtering tank is connected with the treatment tank through a connecting pipe; a water outlet pipe is arranged on the treatment tank; a working surface layer is arranged on the inner wall of the filtering tank; a coarse filtering layer, a fine filtering layer and a deodorizing layer are sequentially arranged in the filtering tank from top to bottom; the treatment tank is sequentially divided into an anaerobic chamber, an aerobic chamber and a sterilization chamber by clapboards; the coarse filtering layer or / and the fine filtering layer is / are movably mounted on a supporting plate in the filtering tank after penetrating through mounting holes in the side wall of the filtering tank, grooves matching with bulges on the bottom surfaces of the coarse filtering layer and the fine filtering layer are formed in the supporting plate, and a sealing cover is arranged on each mounting hole.

Description

technical field [0001] The invention relates to sewage treatment equipment and belongs to the technical field of water purification. Background technique [0002] Water resources are the most critical resources for human production and life, but nowadays, the ecological environment has been severely damaged and water bodies are seriously polluted. The protection of water resources and the control of water pollution have become the most concerned issues in modern society. China is a country with severe drought and water shortage. The total amount of fresh water resources is 2,800 billion cubic meters, accounting for 6% of global water resources, ranking fourth in the world after Brazil, Russia and Canada, but the per capita is only 2,200 cubic meters, which is only 1 / 4 of the world's average level. One-fifth of that of the United States is one of the 13 countries with the poorest per capita water resources in the world. After deducting the difficult-to-use flood streams and...
