Abstract

The invention discloses a subsurface flow type constructed wetland sewage treatment system, which is suitable for the field of urban domestic sewage treatment. The subsurface flow type constructed wetland sewage treatment system comprises a pool body, a water inlet groove, a water guide groove, a water distribution groove, a water collecting component, a filler and plants, wherein the pool body is a soil dam base body, and an anti-seepage geomembrane is laid on the inner side of the pool body; the water inlet groove, the water guide groove and the water distribution groove, which are connected side by side and communicated with an inner cavity are arranged at one end of the pool body, the water distribution groove is communicated with the filler in the pool body, the water collecting component is arranged at the other end of the pool body, the water collecting component is connected with a drainage pipe, an end of the water inlet groove is connected with a water inlet pipe, and the plants are placed on the ground of the pool body. The subsurface flow type constructed wetland sewage treatment system disclosed by the invention has the advantages of low investment and operation cost, capability of taking materials locally, short construction period, on-site assembly and combined installation, convenience, fastness, stable and reliable operation, standardized parts are produced in factories, the water guide groove and the water distribution groove can be randomly disassembled, assembled, expanded or moved according to actual situations of engineering, the flexibility in construction of constructed wetland is greatly improved and the application range is expanded.

Description

technical field [0001] The invention relates to an underflow artificial wetland sewage treatment system, which is suitable for the field of urban domestic sewage treatment. Background technique [0002] Constructed wetland sewage treatment system has the advantages of low investment, good effluent quality, strong impact resistance, increased green area, improved and beautified ecological environment, simple operation, low maintenance and operation costs, etc. This technology is suitable for my country's national conditions, especially for the vast rural areas , Sewage treatment in small and medium-sized cities has extremely broad application prospects. [0003] The sewage in the submerged constructed wetland sewage treatment system flows in the filler layer below the planting soil layer. The sewage is purified through the comprehensive effects of plant root absorption, biofilm degradation on the surface of the filler, and filler adsorption. The sanitary conditions are good an...
