AI Technical Summary

Technical Problem

In the existing ecological sewage treatment equipment, the sludge stays in the anaerobic tank for a short time, which makes it difficult for microorganisms to act fully, the sludge utilization rate is not high, and the treatment effect is not good.

Method used

An ecological sewage treatment equipment based on gas lift and return is designed. The discharge head is moved circularly in the anaerobic tank through the driving mechanism to increase the range of sludge application, and the trajectory radius of the discharge head is changed through the orientation switching mechanism to improve the comprehensive spraying ability of sludge.

Benefits of technology

By increasing the range of sludge application and improving its distribution uniformity, the degradation and conversion effect of microorganisms on organic matter is improved, and the utilization rate of sludge and the sewage treatment effect are improved.

Abstract

The invention relates to the related technical field of sewage treatment, in particular to ecological sewage treatment equipment and an ecological sewage treatment system based on gas stripping reflux. The ecological sewage treatment equipment based on gas stripping reflux comprises a box body as well as a first partition plate, a second partition plate and a third partition plate which are arranged in the box body and divide the interior of the box body into an anaerobic tank, an anoxic tank, an aerobic tank and a separation tank, the membrane piece is arranged in the separation tank and divides the separation tank into a clear water cavity and a sludge cavity which are distributed up and down, and sludge in the sludge cavity can be circulated into the anaerobic tank by a backflow mechanism arranged on the box body; during working, the discharge head can do circular motion in the anaerobic tank, and the direction switching mechanism can change the track radius of the circular motion of the discharge head, so that sludge flows back into the anaerobic tank in a gradual diffusion manner, the comprehensiveness of sludge spraying is improved, and the effect that microorganisms degrade and convert organic matters under an anaerobic condition is ensured.
