Main Constraints and Solutions for Urban Sewage Reclamation
Urban sewage recycling is one of the effective ways to improve ecological environment and to alleviate water supply and demand contradiction in urban areas. This paper analyzes the utilization condition and main constraints of recycling water in China, and believes that too many quality standards for recycling water lead to complex pipe network, and another main factor restraining sewage reclamation is the shortage of buffer storage link of recycling water. The author suggests incorporating the types and standards of recycling water to simplify pipe network, decentralize the reuse and use landscape water surface as a solution for buffer storage, and combining the four feasible recycling water modes being brought forward in the practices in China.
