Description

A micro-power integrated equipment of A²O

technical field

The utility model relates to the field of water treatment, and relates to a purification tank for sewage treatment in new rural areas, in particular to an A²O micro-power integrated equipment.

Background technique

Septic tanks are an important part of the rural sewage treatment process. The septic tanks under the existing technology have a single function, and only have the function of preliminary treatment of sediments, suspended solids, and floating solids in rural sewage, and do not have advanced treatment. process, so the effect of sewage treatment is not good. Moreover, the volume of the upper and lower shells of a conventional septic tank accounts for about 50% of the total volume of the septic tank. The assembly connection method is generally sealed by glue on site, and then connected with bolts. The workload is large and the sealing effect is poor.
