Problems solved by technology
The traditional sewage treatment system is clogged, partial uneven water flow leads to dead zones and cut-offs, occupies a large area, it is difficult to maintain long-term activity, and it is difficult to operate all year round at low temperatures.
The sundries generated during the operation of sewage treatment cannot be treated, which is easy to cause blockage, and the structure is very complicated

The invention discloses a stepped wetland water treatment system which comprises a sewage tank, a primary filter tank, a secondary filter tank and a plurality of horizontal subsurface wetlands, the sewage tank, the primary filter tank and the secondary filter tank are sequentially connected through a slow flow belt I, and a porous pipe is arranged above the secondary filter tank; the secondary filter tank is sequentially connected with the plurality of horizontal subsurface wetlands through a slow flow belt II, and porous filter baffles are arranged on the plurality of horizontal subsurface wetlands. The system is simple in structure, the sewage treatment effect can be effectively improved through filtering of the thick and thin grids and the porous pipe, each layer of horizontal subsurface wetland is provided with the porous filtering baffle, large-particle impurities in the wetland can be effectively filtered out, cleaning is convenient, and the service life of the horizontal subsurface wetland can be prolonged through the waterproof coating.
Description
technical field [0001] The invention relates to a stepped wetland water treatment system. Background technique [0002] Constructed wetlands are man-made ecosystems of soil, plants, and microorganisms. They are often used to purify sewage. They have the characteristics of low investment and operating costs and stable treatment effects. They are common treatment processes for small-scale sewage treatment. The traditional sewage treatment system has problems such as blockage, partial uneven water flow leading to dead zones and cut-offs, large footprint, difficulty in maintaining long-term activity, and difficulty in operating all year round at low temperatures. The sundries generated during the operation of sewage treatment cannot be treated, which is easy to cause blockage, and the structure is very complicated. Contents of the invention [0003] The object of the present invention is to provide a stepped wetland water treatment system with convenient connection in order t...
