To accelerate the progress of urban wastewater resource utilization and solve the problem of severe deficiency of water resources and to guarantee the sustainable exploitation and utilization of urban water resource,the following problem must be solved through the study.

Study on the Application of BOT in China s Urban Sewage Reclamation Infrastructure;

The scale-up continuous test of magnetic flocculation and high gradient magnetic separation of municipal sewage was carried out on the basis of lab experiment.

Objective To observe the change of microbial indexes caused by the treatment of municipal sewage treatment plant.

The composite process of contact oxidation and enhanced coagulation treating municipal sewage was investigated on the condition of low carbon source.

An experimental research was carried out to simulate the operating condition of low,middle and high concentration town sewage treatment by activated sludge system in sewer lines and ditches.

It is urgently to built town sewage treatment plant and increase sewage water treatment ratio for improving water environment quality.

A Pilot Study of Anaerobic-Aerobic Highrate Trickling Filter Process in Sewage Treatment;

Removal of ammonia nitrogen in sewage by bio-eco-filtrat ion is a new sewage treatment process, which is a combined biological and ecolog ical treatment using their synergy for the conversion.
