The invention discloses an artificial wetland system which comprises a grid tank, a hydrolysis acidification tank and an artificial wetland tank which are sequentially connected, wherein grids are arranged inside the grid tank; the bottom of the grid tank is provided with a sludge discharge hopper; and the tank wall of the grid tank is provided with a sludge discharge pipe for discharging sludge. The artificial wetland system is provided with the grid tank, so polluted water firstly enters the grid tank to filter out massive pollutants, thereby preventing some larger impurities from blocking the artificial wetland tank. The hydrolysis acidification tank can eliminate small inorganic granules and organic matters in the water body. The artificial wetland tank is provided with five layers, thereby enhancing the filtration effect. The microbe layer can well enhance the actions of microbes in the water body and enhance the sewage treatment efficiency. The back flush pipeline arranged in the artificial wetland tank can effectively remove blockage.
Description
technical field [0001] The invention relates to an artificial wetland system, which belongs to the technical field of micro-polluted water body treatment. Background technique [0002] Constructed wetland is a ground similar to swampland that is artificially constructed and operated under control. Sewage and sludge are distributed to the artificially constructed wetland in a controlled manner. When sewage and sludge flow in a certain direction, they are mainly used It is a technology for treating sewage and sludge through the triple synergy of physics, chemistry and biology of soil, artificial medium, plants and microorganisms. [0003] Constructed wetland is a new type of sewage treatment technology that emerged in the 1970s. It is widely used in small towns and rural areas because of its large buffer capacity, convenient management, simple process, low investment, low operating costs, and high environmental benefits. in sewage treatment. [0004] However, existing constr...
