Abstract:
The present invention provides a sewage treatment system, a construction method for a sewage treatment system, and a sewage treatment cylinder. The sewage treatment system comprises a foundation layer and a cylindrical sewage treatment tank arranged on the foundation layer, wherein the sewage treatment tank comprises a first treatment space enclosed by side walls, the first treatment space is divided into three sub-areas which are sequentially adjacent, namely, an anaerobic sub-area, an anoxic subarea and an aerobic sub-area, each sub-area respectively runs vertically from the top to the bottom of the sewage treatment tank, and two adjacent subareas are sequentially in communication, such that sewage in the sewage treatment tank sequentially flows through the anaerobic sub-area, the anoxic sub-area and the aerobic sub-area along a vertical serpentine path; and a plurality of layers of process platforms which are sequentially arranged from top to bottom are built around the sewage treatment tank above the foundation layer, and the process platforms are configured for carrying a secondary sedimentation apparatus and an advanced treatment apparatus that treat the sewage discharged from the sewage treatment tank, and carrying a power distribution apparatus that sustains operations of the sewage treatment tank. Construction land is reduced, and the space utilization in a horizontal plane is improved.
