With the development of China's economy and the acceleration of urbanization, the living standards of rural residents in China have improved greatly. Due to the continuous development of rural water supply business, the popularization of toilet flushing, shower, washing machine and other sanitary facilities, resulting in more and more rural domestic sewage, sewage discharge is huge. According to a survey, 96% of villages do not have drains and sewage treatment systems, and domestic sewage is discharged untreated along roadside ditches or pavements into neighboring water bodies, which poses a serious danger to the rural ecological environment. Therefore, there is an urgent need to take measures to effectively manage rural sewage in China. For rural areas and some remote areas, the pipeline network coverage is usually low, if the construction of large-scale sewage treatment plants, usually need to support the construction of large-scale municipal pipelines, which costs a lot of money, but also not easy to manage. For the actual situation of rural sewage, as well as China's sewage treatment business there is a large funding gap, China's rural areas are more suitable for the use of integrated sewage treatment equipment.
The use of integrated sewage treatment equipment can relieve the pressure of municipal pipeline construction. In addition, for the diversion system drainage system, the integrated wastewater treatment equipment treated sewage can be discharged directly into the storm water pipe or discharged into the water body nearby, neither pollute the environment, nor increase the pressure of sewage pipes. Moreover, integrated wastewater treatment equipment has a low investment, low energy consumption, high processing efficiency, small footprint, convenient management and a series of advantages, in this situation, integrated wastewater treatment equipment should be promoted in the vast rural areas.
