Problems solved by technology
[0004] Compared with other traditional sewage treatment processes, the constructed wetland has a longer hydraulic retention time in the sewage treatment process. The organic matter, nitrogen, phosphorus and other harmful substances in the sewage of the constructed wetland are mainly removed by the adsorption of the filter material, and the gaps of the filter material will be absorbed. A small amount of microorganisms, microorganisms can remove organic matter and nitrogen and phosphorus in sewage by their own action, but the microbial content in the filter material is small, so the microbial action is limited, and excessive free microorganisms can easily lead to filter material blockage

Abstract
The invention discloses an assembled aerobic-anaerobic constructed wetland system, which includes a constructed wetland pool, a water inlet pipeline, an aeration device, a water outlet unit, and an immobilized microbial plate. The constructed wetland pool has five layers from top to bottom, in order of : Gravel layer, first immobilized microorganism layer, artificial mixed matrix layer, second immobilized microorganism layer and coarse stone layer; gravel layer is provided with water inlet pipe; first immobilized microorganism layer and second immobilized microorganism layer There are immobilized microbial plates, and an aeration device is installed at the bottom of the first immobilized microbial layer; the water outlet unit is composed of a water outlet hole, a sump and a sump drain; the constructed wetland pool is mainly composed of an upper pool body, a middle pool body and a bottom pool body. In part, the artificial wetland pool is constructed of steel plate materials. The invention has the following advantages: the organic combination of immobilized microorganisms, microorganism aerobic anaerobic treatment and artificial wetland strengthens the function of microorganisms in the artificial wetland.
Description
technical field [0001] The invention relates to the field of sewage treatment, in particular to an assembled aerobic-anaerobic constructed wetland system. Background technique [0002] Constructed wetland is a new type of sewage treatment process developed in the 1970s. It utilizes the triple synergy of physics, chemistry and biology in the natural system to purify sewage. Constructed wetland sewage treatment technology has the advantages of good treatment effect, high nitrogen and phosphorus removal rate, convenient operation and maintenance, low engineering infrastructure and operation costs, so it is widely used in domestic sewage treatment, industrial sewage treatment, mining and oil exploration, agricultural sites source and non-point source pollution and water eutrophication. [0003] The traditional activated sludge method is widely used in sewage treatment, mainly because activated sludge contains a large number of active microorganisms, which can quickly and effect...
