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 a wastewater treatment process with solar energy heat preservation effect. The wastewater treatment process with the solar energy heat preservation effect comprises an artificial wetland tank, a water inlet pipeline, an aeration device, a water outlet unit, immobilized microorganism boards and a solar panel, wherein the artificial wetland tank sequentially comprises five layers, namely a gravel layer, an aerobic immobilized microorganism layer, an anaerobic immobilized microorganism layer, a steel slag layer and a sand-stone layer, from top to bottom; a water inlet pipeline is arranged in the gravel layer, the immobilized microorganism board is respectively arranged in each of the aerobic immobilized microorganism layer and the anaerobic immobilized microorganism layer, the aeration device is arranged between the aerobic immobilized microorganism layer and the anaerobic immobilized microorganism layer, and a steel wire mesh is arranged between the aerobic immobilized microorganism layer and the gravel layer; the water outlet unit is composed of a water outlet hole, a water collecting tank and a water collecting tank drainage pipe; the artificial wetland tank adopts a reinforced concrete structure and is provided with a heat preservation layer.
Description
technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment process with solar heat preservation effect. 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 e...
