Integrated ecologic trench waste water aerobic treatment method

Abstract

An integrated ecologic trench waste water aerobic treatment method comprises the steps of introducing waste water / sewage of a water body of which the nitrogen and phosphorous and organic pollutant is reduced by early pretreatment to a certain standard into an ecologic trench by building the ecologic trench; aerating by using a physical action of the waste water / sewage and the ecologic trench; discharging oxygen by using plant root systems; performing aerobic microorganism degradation by using microorganism of matrixes of the ecologic trench; using actions of the matrixes of different layers of the ecologic trench to perform absorption removal treatment; using an absorption action of plants with large biomass to realize further treatment of the waste water. Three layers of matrixes are paved on the surface of the ecologic trench; the lowermost layer, namely the third matrix layer (5) is cobble; the middle layer namely the second matrix layer (4) is zeolite; the uppermost layer, namely the first matrix layer (3) is of fine sand particles; herb of alligator alternanthera or watermifoil aquatic plants are planted in the surface layer (1) of the ecologic trench; perennial pennisetum hydridum and garden sorrel or aspen fast growing tree species are planted at trench edges (2) at two sides of the ecologic trench.

Description

technical field [0001] The present invention relates to an aerobic treatment method for integrated ecological canal wastewater, which belongs to the technical field of wastewater treatment. Background technique [0002] Waste / sewage pollution has a direct or indirect negative impact on people's life and production. With the continuous development of industry and agriculture, the degree of water pollution is becoming more and more serious, resulting in shortage of water resources and deterioration of water bodies. The research and development of waste / sewage treatment processes and methods has been in the process of continuous advancement. According to different types and properties of waste water, physical methods, chemical methods, and biological methods are generally used, or a combination of multiple processes. With the continuous research and development of waste / sewage treatment technology, the waste / sewage treatment technology of constructed wetlands is also c...
