High-efficiency compound biological pond and sewage treatment method

Abstract

The invention discloses a high-efficiency compound biological pond and a sewage treatment method. The high-efficiency compound biological pond is used for the advanced treatment of sewage, wherein the high-efficiency compound biological pond comprises a high-efficiency compound biological pond body, and a water inlet and a water outlet are arranged on the high-efficiency compound biological pond body; at least one flow guide wall used for proofing water and guiding flows is arranged between the water inlet and the water outlet to form at least two galleries in the high-efficiency compound biological pond body; and compound biological zones used for purifying sewage, an anoxic zone and a filler box are arranged in the high-efficiency compound biological pond body. According to the high-efficiency compound biological pond in the invention, aquatic plants are used as a main body, and different kinds of aquatic plants can be collocated in different zone and can adapt to the water quality and the climatic changes; meanwhile, fishes which have strong pollution resistibility and mainly take plankton, algas and organic matter particles as food are input into the pond; and a complete ecological system is formed by the aquatic plants, the aquatic animals and microorganisms in water so as to guarantee the high efficiency of the high-efficiency compound biological pond.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a high-efficiency composite biological pond and a sewage treatment method. Background technique [0002] Water is the basis for the survival of various living organisms. At present, water pollution and shortage of water resources have become common problems restricting the development of the world. In recent years, my country's society and economy have developed rapidly, but it has brought about a series of problems such as water pollution and overexploitation of water resources. [0003] At present, in view of the current situation of my country's water resources, various sewage treatment processes have been continuously applied and developed in my country's sewage treatment. Among them, the traditional activated sludge process is relatively mature and stable in operation. For the sewage treated by the traditional process, generally there are still a considerable amount of pol...
