Abstract

The invention discloses a sealed type sewage treatment device. The sealed type sewage treatment device comprises a treatment tank, wherein the upper end of the treatment tank is equipped with a sealing cover; the upper end of the sealing cover is equipped with a water inlet tube; the water inlet tube is communicated with the treatment tank; a water collecting slot is formed in the middle part of the treatment tank; a water outlet is formed in the upper part of the water collecting slot; a U-shaped water seal is arranged on the water outlet; the front end of the U-shaped water seal is communicated with the treatment tank through the water outlet; the tail end of the U-shaped water seal is communicated with the water collecting slot; a propeller is arranged on the middle part of the treatment tank; a filler hole is formed in the upper end of the sealing cover; a filler device is arranged in the filler hole; the filler device comprises a filler cover and inclined tubes; and the inclined tubes are mounted at the lower end of the filler cover; biological fillers are bundled on the inclined tubes, so that the problem that COD removal efficiency of the anaerobic bacteria is reduced as oxygen molecules in air are soaked into sewage in a continuous sewage treatment process is solved.

Description

technical field [0001] The invention relates to sewage treatment, in particular to a closed sewage treatment device. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. The treated sewage can effectively remove the harmful components in the water and make the molecules harmless. Usually, the sewage is poured into the anaerobic tank for anaerobic treatment. After anaerobic treatment for a period of time, then New sewage is injected, and the raw sewage is discharged to the primary sedimentation tank for further treatment; [0003] During continuous anaerobic treatment, since the water flow is circulating, it is easy to cause oxygen molecules in the air to immerse in the sewage, which reduces the efficiency of anaerobic bacteria in removing COD. Contents of the invention [0004] The purpose of the present invention is to provide a closed sewage trea...
