Problems solved by technology

The reuse of rural sewage can effectively alleviate part of the problem of scarcity of irrigation water resources, but its ammonia nitrogen, total phosphorus and other toxic and harmful substances often seriously exceed the standard, and the water volume is unstable and small
[0003] On the other hand, as an important water resource for irrigation, rainwater is often discharged directly due to the lack of regulation and storage facilities in the vast rural areas, which is likely to cause loss and waste of water resources and seasonal water shortages.
Another important reason why rainwater is not widely used for reuse irrigation is that the initial rainwater is highly polluted and needs to be treated before it can be used.
However, the establishment of the initial rainwater system alone is not compatible with the level of economic and social development in my country's rural areas, and inevitably faces the problems of land use and cost

Abstract

The invention discloses a new rural sewage treatment irrigation system and treatment method. The system comprises a sewage collection unit, a rainwater collection unit, a sand settling unit, an ecological retention pond unit and an artificial wetland unit. The treatment system provided by the invention skillfully combines the regulation and storage of rainwater with the treatment of domestic sewage, and uses the unpowered ecological retention pond combined with the artificial wetland to remove toxic and harmful pollutants in rural sewage, which is effective for COD, TN, TP and The highest TSS removal rate can reach 65.3%, 85.0%, 88.7% and 35.6%. The treated water can be directly used for garden irrigation, which realizes the resource utilization of water, and the system occupies a small area and has low operating costs. It is suitable for the treatment of dispersed sewage.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a new rural sewage treatment irrigation system and treatment method. Background technique [0002] Rural domestic sewage refers to the sewage discharged from bathing, washing clothes, toilets and kitchens during residents' daily life. At present, the treatment rate of domestic sewage in rural areas of our country is low, and most of the domestic sewage is directly discharged without treatment, or cannot be discharged in a centralized manner, which seriously affects and threatens the living environment and health of the rural masses. The traditional rural sewage treatment method is to discharge the sewage directly to the receiving water body or nearby farmland after being treated in a septic tank. The reuse of rural sewage can effectively alleviate part of the problem of scarcity of irrigation water resources, but its ammonia nitrogen, total phosphorus and ot...
