Ecological integration system and domestic sewage treatment method

Abstract

The invention provides an ecological integration system and a domestic sewage treatment method. The ecological integration system includes a settling tank, an aerobic fermentation tank and an irrigation area, wherein a floating-body-type absorption system is set at the surface of the settling tank, scavenger fish are bred in the aerobic fermentation tank, the bottom of the aerobic fermentation tank communicates with the settling tank, and is provided with a switch, and the irrigation area is composed of cultivation substrates and plants; the floating-body-type absorption system includes fast-growing aquatic plants, adsorbent substrates, and floating bodies; the adsorbent substrates are used after being soaked with microbial bacterial fluid. Purifying rural sewage by using the ecological integration system of the invention is easy to operate, has high purifying efficiency, and has significant economic benefit, thus the ecological integration system is worthy for large-scale promotion.

Description

technical field [0001] The invention belongs to the technical field of sewage, and in particular relates to an ecological integration system and a domestic sewage treatment method. Background technique [0002] The random discharge of rural domestic sewage is an important factor that causes rural environmental pollution, endangers the physical and mental health of rural residents, and restricts the development of rural economy. With the development of society, although the treatment of rural domestic sewage has been gradually improved, there are still serious problems , such as weak rural economic foundation, lack of funds, lack of professional and technical personnel, and low management level. The rural domestic sewage treatment system in the prior art is mainly a device that uses biological digestion to treat sewage. For example, it mainly It consists of a water inlet well and a regulating tank. When the sewage enters the water inlet well, it will be transported to the reg...

[0002] The random discharge of rural domestic sewage is an important factor that causes rural environmental pollution, endangers the physical and mental health of rural residents, and restricts the development of rural economy. With the development of society, although the treatment of rural domestic sewage has been gradually improved, there are still serious problems , such as weak rural economic foundation, lack of funds, lack of professional and technical personnel, and low management level. The rural domestic sewage treatment system in the prior art is mainly a device that uses biological digestion to treat sewage. For example, it mainly It consists of a water inlet well and a regulating tank. When the sewage enters the water inlet well, it will be transported to the regulating tank through the grille and the lifting pump, and then the air will be introduced into the air through the aeration pipe for aerobic biological treatment. This device is in the process of A large amount of carbon sources are consumed during treatment, and a large amount of nutrients in domestic sewage are wasted
