Problems solved by technology
The existing artificial wetland sewage treatment system is relatively popular in southern my country, but it occupies a large area and is prone to smell and affect the surrounding environment.
There are also examples of application in northern regions, but due to climatic factors such as cold winter, the operation is unstable and the treatment effect is poor, so it is limited

Abstract
The invention discloses a reinforced composite artificial wetland sewage treatment system which comprises a water distribution pond as well as a composite packing wetland zone, a water collecting pond and a landscape pond which are built beside the water distribution pond, wherein the composite packing wetland zone is internally provided with an upper wetland layer, an intermediate wetland layer and a lower wetland layer; the upper wetland layer and the intermediate wetland layer are isolated by geotechnical cloth and a storage and drain board; the intermediate wetland layer and the lower wetland layer are isolated by concrete; the upper wetland layer is a surface permeation flowing type wetland layer; the intermediate wetland layer is an undercurrent type wetland layer; the lower wetland layer is also an undercurrent type wetland layer; the upper wetland layer, the intermediate wetland layer and the lower wetland layer are all internally provided with water distribution systems uniformly. By adopting the system, the occupied area is reduced, the investment is reduced, and the purpose of flow stabilization is achieved as the three wetland layers are provided with independent water inlets which can be selectively opened and closed according to the sewage treatment amount.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an enhanced compound artificial wetland sewage treatment system. Background technique [0002] At present, the treatment rate of urban sewage in my country is only about 20%, and most of the sewage treatment plants use activated sludge method, oxidation ditch method, intermittent activated sludge method and other treatment processes. These treatment methods have high investment and energy consumption. High, high operational management requirements and other deficiencies. Compared with the traditional sewage treatment methods, the currently popular constructed wetland sewage treatment system is gradually popularized and applied to decentralized sewage treatment and terminal purification treatment of sewage treatment plants due to its advantages of low investment and simple operation. The existing constructed wetland sewage treatment system is relatively popular in souther...
