Embodiment 1

[0037] Landscape multivariate rural wastewater treatment systems such as figure 1 As shown, it includes inflow wells, anaerobic ponds, anoxic ponds, contact oxidation ponds and constructed wetlands connected in sequence. The constructed wetlands are vertical subsurface flow constructed wetlands, and a return flow system is set in the vertical subsurface flow constructed wetlands.

[0038] The anaerobic tank includes at least two first anaerobic tanks and second anaerobic tanks connected in series.

[0039] Such as figure 2 As shown, the anaerobic tank is provided with a water inlet 1 and a water outlet 2, and the side near the water inlet 1 is provided with a deflector 3 parallel to the wall of the anaerobic tank, and the deflector 3 will The pool body of the anaerobic tank is divided into a water inlet area 4 and a treatment area, the lower end of the deflector 3 is provided with an opening connecting the water inlet area 4 and the treatment area, and the treatment area is ...

Abstract

The invention provides a landscape-diversified countryside sewage treatment system. The landscape-diversified countryside sewage treatment system comprises a water inlet well, an anaerobic tank, an anoxic tank, a contact oxidation tank and an artificial wetland. The landscape-diversified countryside sewage treatment system provided by the invention is used as an effective manner of solving the current countryside sewage treatment difficulty in terms of economy and reliability; vegetations in a filtering tank of the wetland have ornamental values and are especially applied to villages with shortage of land resources, higher agglomeration degree and rural tourism industry basis. Compared with a trickling filtration technology, the landscape-diversified countryside sewage treatment system provided by the invention is free of electricity fee and professional operation and maintenance personnel; compared with an ecological combined pond treatment system, the defects of large occupied area,strong seasonality and high vegetation maintenance input are solved; compared with a contact oxidation treatment system, the defects of poor quality of effluent water, low removal of nitrogen and phosphorus and odor of the effluent water are solved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a multi-landscape rural sewage treatment system. Background technique [0002] With the rapid economic development in rural areas, the discharge of rural sewage continues to increase, becoming the main source of nitrogen and phosphorus pollution in many watersheds, resulting in water pollution and eutrophication of receiving water bodies and downstream estuaries and lakes, and destroying the water ecological environment. . The content of nitrogen and phosphorus nutrients in rural sewage is high, the coefficient of variation of water quality and water quantity is large, and because people live relatively scattered, the drainage pipe network is not perfect, and it is difficult to collect. However, the technical means of urban sewage treatment have complicated procedures and high operation and management costs, which are not suitable for popularization and appl...
