Integrated sewage treatment equipment

There are many sewage treatment processes used both domestically and internationally, which are mainly divided into two types: activated sludge method and biofilm method. The common aeration method, oxidation ditch method, A/B method, and A2/O method belong to the former, while the biological rotary disc and contact oxidation method belong to the latter. Integrated sewage treatment equipment is a device that integrates a primary sedimentation tank, I and II level contact oxidation tanks, a secondary sedimentation tank, and a sludge tank, and performs air blowing aeration in the I and II level contact oxidation tanks to effectively combine the contact oxidation method and activated sludge method, while possessing the advantages of both and overcoming their disadvantages, thereby further improving the level of sewage treatment.
