| description | The invention provides a construction method of a root hole wetland. The construction method comprises the following steps: S1, mixing aluminum sludge and sandy soil according to a certain weight ratio to form aluminum sludge sandy loam soil; s2, in the initial stage of wetland construction, aluminum sludge sandy loam and plant straw are buried in a layered mode, and an artificial wetland bed is constructed; the water content of the plant straws is lower than 20%, and the main axis direction of the plant straws is parallel to the subsurface layer flow direction of the wetland inlet water passing through the wetland bed; s3, aquatic and/or hygrophyte capable of forming natural root holes is planted on the artificial wetland bed. According to the invention, the capability of removing phosphorus and nitrogen in sewage of the root hole wetland can be effectively improved, the problem that the conventional root hole wetland is easy to block is solved, the operation effect of the root hole wetland can be improved i |
