Abstract

The application discloses a low-temperature operation treatment system for rural domestic sewage and a treatment method thereof. The low-temperature operation treatment system for rural domestic sewage comprises a solar heat collection and power generation system, a temperature control system, a biological treatment reactor, and a greenhouse insulation artificial wetland; the solar heat collection and power generation system comprises a photovoltaic panel, a charge-discharge controller, a battery, a solar heat collector, a heat exchanger, and an insulation water tank; the temperature control system comprises temperature sensor I, temperature sensor II, a temperature controller, a switch contactor, auxiliary heater I, and auxiliary heater II; the biological treatment reactor comprises an anaerobic pool, an anoxic pool, and a multilevel waterfall biological turnplate; the greenhouse insulation artificial wetland comprises an artificial wetland, LED plant growth lamps and a plastic greenhouse. The system provides thermal insulation for the treatment of biological-artificial wetland sewage by the combination of solar energy and greenhouse, the efficiency of sewage treatment at low temperature is improved, zero energy consumption is achieved, and economic value is created.

Description

technical field [0001] The invention belongs to the technical field of domestic sewage treatment, and in particular relates to a treatment system and a treatment method for rural domestic sewage operating at low temperature. Background technique [0002] With the maturity of urban sewage treatment technology, the main source of water environmental pollution in my country is not urban domestic sewage, but agricultural pollution sources, of which rural domestic sewage also accounts for a part, so it is increasingly necessary to study the process suitable for rural life. The quality and quantity of domestic sewage in rural areas vary greatly, and the area is wide and scattered. Combining the characteristics of rural areas and economic development, and comparing the characteristics of different treatment technologies, it can be seen that the biological-constructed wetland combination process is suitable for the treatment of rural domestic sewage, which can not only meet the sewa...
