How to set up the sewage treatment discharge standards? Whether the higher the sewage treatment discharge standards are, the better environment quality will be? According to the theoretical study of the whole life cycle numerical simulation of sewage treatment and efficient utilization of water resources, it is suggested that the state shall establish different sewage treatment discharge standards for different functions of sewage, to avoid excessive sewage treatment and excessive waste and to fully understand the sewage as the concept of important water resources. How to solve the problem of urban water resources and water environment in China? What kind of the urban water system should be in the future? Fully consideration of seven units, i.e. water sources, water plants, production- and household-use, sewage treatment plants, urban rivers and artificial wetlands, rainwater collection systems and sponges, and receiving water bodies, of the urban water natural cycle and social cycle is recommended. The Chinese government shall take a leading role in the environmental pollution control, and the idea of system engineering shall be adopted in the comprehensive improvement. |
