[Application of wastewater treatment and reuse techniques: related problems and perspectives in Shenyang].
To resolve the severe scarcity of water resources and to alleviate the pollution of wastewater disposal, the comprehensive urban wastewater reclamation and reuse projects will be launched in Shenyang in the next 5 - 10 years, and the wastewater reclamation and reuse rate will reach 50%. This paper summarized the routine technologies and new treatment processes of wastewater treatment, such as soil-aquifer treatment (SAT) , membrane biological reactor (MBR), and cyclic active sludge system (CASS), and pointed out that owing their unique advantages, SAT and MBR were regarded as the promising techniques in this field. A short list of examples in wastewater treatment and reuse was presented, and the societal, environmental, and economical benefits of wastewater reuse were analyzed. The existing problems of wastewater reuse were also discussed.
