The section of the tank body is in an inverted trapezoid shape.
The water outlet end of the pressure pump is provided with a water distributor for distributing water for the pool body.
The inner walls of the periphery of the tank body are provided with water distribution layers, and the bottom of the tank body is provided with a drain pipe; the water distribution layer is communicated with the water distributor; the water discharge pipe is communicated with the water outlet well.
The wetland plants are reeds or other aquatic plants.
Compared with the prior art, the beneficial effects of the utility model are that:
the application optimizes the traditional wetland treatment technology, develops the high-efficiency wetland purification treatment system, well solves the problems of dispersion of domestic sewage in villages and small towns, complex nutrient components and the like, and provides a feasible treatment scheme for the treatment of the domestic sewage in rural areas and other sewage which can not be merged into a municipal pipe network for treatment.
The high-efficiency wetland purification treatment system is developed on the basis of the traditional constructed wetland, and can purify sewage and produce an ecological technology of biomass energy; through the synergistic effect of floating plants such as reed and the like and microorganisms, the metabolic activity of the microorganisms at the roots of the plants is utilized to absorb, accumulate, degrade and convert pollutants in the sewage, thereby realizing the sewage purification function.
The high-efficiency wetland purification treatment system can effectively remove pollutants such as COD, BOD5, NH3-N, TP, SS and the like in sewage by adopting the mutual intersection and mutual assistance of the functions of rhizosphere filtration, root system fixation, root zone degradation, plant absorption, plant transformation, plant volatilization and the like according to different forms, characteristics and existing modes of the pollutants; the pollutant removal rate is high. The effluent quality can reach the first grade A standard of national regulation 'discharge Standard of pollutants for municipal wastewater treatment plants', meanwhile, the treatment effect is thorough, no secondary pollution is generated, and the removal rate of COD and ammonia nitrogen is up to more than 90%.
The construction scale is flexible and can be large or small. The centralized sewage plant in villages and towns can be built by using abandoned lands, river channels and the like, and facilities shared by single family or several families can be built by using the vacant lands in front of and behind the houses. Is suitable for use in: villages, towns and communities with the scale of tens of thousands of people; setting a family in a natural village with the scale of dozens of people; can realize zero discharge and treat sewage with high content of heavy metal and organic poison. The high-efficiency wetland purification treatment system can effectively treat pollution sources such as high-concentration percolate, realize the complete absorption of sewage and avoid the secondary pollution of the environment. Can produce a large amount of biomass as an alternative energy source. Other aquatic plants, reeds and other plants can be harvested regularly and used as alternative energy.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
Fig. 1 shows a high-efficiency wetland purification treatment system, which comprises a plurality of collecting wells 1 positioned at indoor underground positions, a sedimentation tank 2 communicated with the collecting wells, a pump well 3 communicated with the sedimentation tank, an ecological wetland 4 communicated with the pump well, and a water outlet well 5 communicated with the ecological wetland; the collecting well is connected with a domestic sewage generating facility (a toilet, a washroom and the like) for collecting pollutants;
the ecological wetland comprises a pool body 41 and wetland plants 42 arranged in the pool body; the wetland plants are reeds or other aquatic plants. The section of the tank body is in an inverted trapezoid shape. The inner walls of the periphery of the tank body are provided with water distribution layers 43, and the bottom of the tank body is provided with a drain pipe 44; the water outlet end of the pressure pump is provided with a water distributor for distributing water for the pool body. The water distributor can be selected from various specifications according to different water quantities; the water distribution layer is communicated with the water distributor; the water outlet pipe 44 is communicated with the water outlet well 5.
