A domestic sewage treatment system utilizing solar energy and its treatment method

Abstract

The invention provides a domestic sewage treatment system utilizing the solar energy and a treatment method of the same. The system comprises a solar system, an adjustment pool, a tower-type biofilter and a land treatment system. The method comprises the steps of utilizing the solar energy as a power for sewage circulation, sequentially treating the domestic sewage by the three phases of the adjustment pool, the tower-type biofilter and the land treatment system, and then draining water which reaches the standards. According to the system and the method provided by the invention, compared with the traditional biotreatment technology, microorganisms are fixed on carriers, thus preventing the loss of the microorganisms and reducing the dosage of the microorganisms; the microorganisms are high in activity, fast in reproduction, wide in adaptability and high in degradation capacity, thus increasing the biotreatment efficiency; meanwhile, the circulation of the sewage in the tower-type biofilter is carried out by utilizing the solar energy, thus reducing the running cost.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment, in particular to a domestic sewage treatment system using solar energy and a method for treating sewage in the domestic sewage treatment system using solar energy. Background technique [0002] With the deepening of our country's environmental protection work, the treatment of scattered domestic sewage in vast rural areas and troops has increasingly become the focus of environmental protection work. Domestic sewage contains a large amount of organic matter, nitrogen and phosphorus and other nutritional pollutants. When the most economical biochemical method is used for treatment, the bacteria that degrade organic matter, nitrogen, and phosphorus are different, and the optimal reaction conditions for each other are different. As a result, the treatment process is complicated, the reaction process is long, and the operation is complicated, which is not suitable for decentralized s...

Domestic sewage contains a large amount of organic matter, nitrogen and phosphorus and other nutritional pollutants. When the most economical biochemical method is used for treatment, the bacteria that degrade organic matter, nitrogen, and phosphorus are different, and the optimal reaction conditions for each other are different. As a result, the treatment process is complicated, the reaction process is long, and the operation is complicated, which is not suitable for decentralized small-scale sewage treatment in rural areas.
