Description

A disinfection device for sewage treatment

Technical Field

The utility model belongs to the technical field of sewage treatment, and particularly relates to a disinfection device for sewage treatment.

Background Art

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 and catering, and is increasingly entering the daily lives of ordinary people.

The existing sewage treatment will first filter the sewage to filter out impurities in the sewage to prevent the impurities from affecting the subsequent sewage disinfection treatment. The filtration of sewage impurities is mostly achieved through a filter screen, but in order to avoid clogging, the existing filter screen is mostly set to a structure with a certain angle tilted. Therefore, impurities accumulate in the low-lying areas of the filter screen, which puts pressure on the filter screen. In the long run, it is easy to cause the filter screen to deform and the filtration quality to decline. It needs to be replaced before it can continue to be used. Moreover, the filter screen is an integral structure and the replacement cost is relatively high. Therefore, a disinfection device for sewage treatment is proposed.
