Abstract

The invention provides a multi-stage combined packing artificial wetland for sewage treatment, which belongs to the technical field of sewage treatment. The multi-stage combined packing artificial wetland used for sewage treatment includes artificial wetland. The artificial wetland includes a pretreatment pool, an inner pool and an outer pool. The pretreatment pool has a pretreatment tank. Stirring blades; the outer pool has a filter tank, and a partition plate 1 is vertically fixed in the filter tank of the outer pool. The partition plate 1 separates the filter tank into a first filter tank and a second filter tank, and The space is connected through the water inlet pipe; the inner pool has a purification tank, and a partition plate 2 is vertically fixed in the purification tank of the inner pool, and the partition plate 2 divides the filter tank into a first purification tank and a second purification tank. The invention has the advantage of being able to perform multiple cycle purification treatments on the sewage.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to a multi-stage combined packing artificial wetland for sewage treatment. Background technique [0002] At present, the method of artificial wetland is widely used in sewage treatment. The existing method of artificial wetland to treat sewage still stays in the treatment of small-scale sewage, but for the large amount of pollution and complex components, the wastewater contains deadly Heavy metals, industrial wastewater that seriously endangers human life and safety, especially some industrial wastewater from isolated point sources, have no feasible treatment process. Constructed wetlands can be divided into surface flow constructed wetlands, horizontal subsurface flow constructed wetlands and vertical flow constructed wetlands according to the system water distribution method and water flow in the wetland system. The existing constructed wetlands in use have a large area an...
