Embodiment Construction

[0017]The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0018]A natural absorption and natural recycling sewage treatment method that allows domestic sewage to flow into the natural ecological area, allowing trees, grass, soil, ditches, animals, and microorganisms in the area to cooperate to absorb and digest organic pollutants in domestic sewage. The treated purified water is obtained, and this process is a natural absorption process; the elevation of the natural ecological area gradually decreases from the inlet end of the sanitary sewage to th...

Abstract

The invention provides a sewage treatment method capable of realizing natural absorption and natural circulation. According to the method, domestic sewage flows into a natural ecological area, trees,grass, soil, ditches, animals and microorganisms in the area cooperate with one another to absorb and digest organic pollutants in the domestic sewage so as to obtain treated purified water, and the process is a natural absorption process; and meanwhile, because pollutants in water can continuously provide nutrient substances for the animals and the plants, the plants in the area can rapidly grow,the animals can rapidly breed and are used in life and production of people, and the process is a natural circulation process. As the method is used for treating the domestic sewage, the method has the advantages of being low in resource consumption, safe to use and free of secondary pollution, ecological circulation and economic circulation can be achieved, and the ecological environment can beimproved fundamentally.

Description

Technical field[0001]The invention relates to the technical field of sewage treatment, in particular to a sewage treatment method with natural absorption and natural circulation.Background technique[0002]Domestic sewage comes from people's daily life. It is discarded into domestic sewage after use of tap water. Compared with other microorganisms, the pollutants in the water are nutritionally balanced for plants. The ratio of carbon, nitrogen, phosphorus and other trace elements Appropriately, it will be quickly transformed and absorbed when entering the natural world and will not pollute groundwater.[0003]The core theories of domestic sewage treatment are two kinds of biochemical treatment: one is the activated sludge method and the other is the biofilm method. Among them, the activated sludge method is widely used. The overall process of the activated sludge method includes the grid tank, the adjustment tank, the grit tank, the lifting pump room, the primary sedimentation tank, the...
