Solar energy constructed wetland system

Abstract

The invention discloses a solar energy constructed wetland system. The system comprises a constructed wetland pond, a water inlet pipeline, an aerating device, a water outlet unit, immobilized microbe plates and a solar panel, wherein the constructed wetland pond comprises five layers from top to bottom, namely, a sand soil layer, a sand and rock layer, an immobilized microbe layer, an artificial mixed substrate layer and a gravel layer in sequence; the water inlet pipeline consisting of a water inlet pipe and a water distribution branch pipe is arranged on the gravel layer; the immobilized microbe plates are mounted on the immobilized microbe layer; the aerating device is mounted on the lower sides of the immobilized microbe plates; a steel mesh is arranged between the immobilized microbe layer and the sand and rock layer; the water outlet unit consists of a water outlet hole, a water collecting tank and a water collecting tank drainage pipe; the constructed wetland pond is constructed through adopting a steel-concrete structure; a thermal insulation layer is arranged at the inner part of the pool body of the constructed wetland pond. The system provided by the invention has the advantage that through combining a microbic method and the constructed wetland organically, the constructed wetland sewage treatment efficiency is improved effectively.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a solar artificial 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 effectively remove organic mat...

AI Technical Summary

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
