An environmentally friendly biological turntable

Abstract

The invention discloses an environment-friendly biological rotating disk. The environment-friendly biological rotating disk comprises a fixing disk, wherein a biological rotating disk body is slidingly connected with the rear surface of the fixing disk through connection rods, water-absorbing sponges are fixedly installed on the inner wall of the biological rotating disk body, fixing rods are fixedly installed on the inner wall of the biological rotating disk, fixing boards are fixedly installed at the ends, away from the biological rotating disk body, of the fixing rods, and a reverse rotating cylinder is slidingly connected with the sides, away from the fixing rods, of the fixing boards. Through cooperative use of the water-absorbing sponges, the reverse rotating cylinder, a rotating shaft, movable grooves, connection columns and sliding rods, a water source can be effectively provided for microorganisms on the biological rotating disk body which rotates out of a water surface, the microorganisms on the biological rotating disk body do not die for lack of water even though the rotating speed of the biological rotating disk is very low, and the survival rate of microorganism colonies is improved, so that a sewage purifying effect is improved, national discharge standard can be conveniently reached by sewage, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of water pollution control, in particular to an environment-friendly biological turntable. Background technique [0002] The biological turntable process is a kind of biofilm sewage biological treatment technology. It mainly treats the sewage to meet the national water quality discharge standard. The filler carrier grows and breeds to form a film-like biological sludge that is a biofilm. When working, the biological turntable is driven by the drive device, so the biological turntable keeps rotating. After a period of time, because the biological turntable is constantly rotating, The part of the water surface where the biological turntable turns out of the sewage, the microorganisms on it alternately contact with the air, and the air continuously dissolves into the water film to increase its dissolved oxygen; the part where the biological turntable turns into the sewage, the biofilm absorbs the organic pollut...

AI Technical Summary

Problems solved by technology

[0003] In the sewage treatment process using the existing biological turntable, the rotation speed of the biological turntable is extremely slow in order to ensure that the microorganisms are not washed away by the sewage on the turntable, which will cause the biological The organisms on the turntable stay in the air for a long time without water supply, which may cause the microbial colony on the biological turntable above the water to dry up and die, which increases the mortality rate of the microbial colony on the biological turntable, thus making the purification of sewage ineffective. If the unqualified sewage enters the river and the farmland is used by people, it may also affect people's health
