China is a country with a shortage of fresh water resources, and the occupation amount of per-capita fresh water resources is only one fourth of the average level of the world. For many years, according to estimation, nearly 2 hundred million tons of industrial sewage and domestic sewage are discharged to rivers and lakes every day in China, wherein nearly 70 percent of the sewage does not reach the discharge standard, so that the water pollution is serious, the water environment is continuously deteriorated, water shortage accidents caused by pollution are continuously generated, not only is the factory stopped, the agricultural production reduced, but also even the factory stopped, the agricultural production is even absolutely harvested, adverse social influence and great economic loss are caused, the sustainable development of the society is seriously threatened, and the survival of human beings is threatened.
The existing sewage treatment methods mainly comprise the following steps: a physical treatment method, namely a wastewater treatment method for separating and recovering insoluble pollutants (including oil films and oil droplets) in a suspended state in wastewater through physical action. Generally, the method of precipitation, filtration, centrifugal separation, air flotation, evaporative crystallization, reverse osmosis and the like is adopted to separate pollutants such as suspended matters, colloidal matters, oils and the like in the wastewater, so that the wastewater is primarily purified. And the chemical treatment method is a method for removing pollutants by adding a chemical reagent into the sewage to enable the chemical reagent to perform chemical reaction with pollutants in the sewage so as to enable the sewage to meet the water quality requirement of discharged water. The methods generally used are: neutralization, coagulation, oxidation reduction, extraction, steam stripping, air stripping, adsorption ion exchange, electroosmosis and the like.
Although the two methods have obvious effects, the management difficulty is high due to strong operation management speciality of the wastewater treatment facility and high technical requirements. Moreover, the sewage treatment facility is overloaded for a long time, so that the sewage treatment efficiency and effect are greatly reduced. And another biological treatment method: mainly adopts certain artificial measures on the basis of utilizing the metabolism of microorganisms to create a good environment which is beneficial to the growth and the propagation of the microorganisms and accelerate the proliferation and the metabolism of the microorganisms, thereby degrading pollutants. But the prior art for purifying sewage is still immature, and the application range is not wide. The existing sewage treatment process and the technology thereof have high investment and operation cost, need specialized management and are suitable for large-scale urban pipe networks; however, since the infrastructure of rural areas falls behind, these methods are difficult to implement in terms of technology, investment and operating costs for the purification and treatment of domestic sewage in villages and small towns. Therefore, all of these methods and processes are not suitable for treatment of domestic sewage in villages and towns and at home.
