Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment device. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people. According to the source of sewage, sewage treatment is generally divided into industrial sewage treatment and domestic sewage treatment.

[0003] Sewage treatment is usually divided into several steps. One of the steps is to concentrate the sewage inside a tank, and then add flocculants to better gather the microorganisms and other impurities in the sewage for the next step of filtration treatment. In this step, the reaction rate is usually accelerated by standing or mechanical stirring. The traditional stirring method is relatively simple, which makes the mixing reaction inefficient. In view of the above problems, a sewage treatment device is proposed to solve the above problems. Utility Model Content
