1, small capital investment. Construction of large-scale sewage treatment plant investment pressure, and integrated equipment, the total investment is very small, the market price of tens of thousands to hundreds of thousands of different, suitable for real estate property, small factories and other social investment in small amounts. This is also more in line with China's "who pollutes, who governs" the principle of pollution control.
2, relieve the pressure of municipal network construction. Construction of large-scale sewage treatment plants often need to support the construction of large-scale municipal pipe network system. For small residential areas, scenic areas, factories and other underdeveloped pipe network construction of sewage treatment plants, both inconvenient management, but also uneconomical. In this case, the use of integrated equipment is more appropriate. In addition, for the diversion system drainage system, the smaller flow of sewage treatment using integrated equipment can be discharged directly into the storm drains or water bodies, without increasing the pressure of sewage pipes.
