Rural domestic sewage treatment device, treatment system and treatment method

Abstract

The invention relates to the technical field of sewage treatment, in particular to a rural domestic sewage treatment device, treatment system and treatment method. The rural domestic sewage treatment device of the present invention adopts inner and outer tanks arranged at intervals, and the inner tank is filled with suspended fillers, which are used as anaerobic biological pools. After anaerobic treatment, the pretreated sewage is discharged into the gap between the inner and outer tanks. Reasonable, easy to use, and high treatment efficiency; the rural domestic sewage treatment system of the present invention is designed according to the characteristics of rural domestic sewage, and adopts grid pools, rural domestic sewage treatment devices, falling water-type constructed wetland units and ecological ponds in series, In order to remove inorganic matter, organic matter (organic carbon), nitrogen and phosphorus in rural domestic sewage in turn, and finally purify the sewage, the removal efficiency is high and the cost is low.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a rural domestic sewage treatment device, a treatment system and a 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 ...

[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
