Research on Suzhou river sullage treatment and energy resource utility

Urban sullage is city garbage´ main source, which include city sewage factory and water supply factory´sullage,drain pipe sullage,water dredge up sullage,and so on. It is still our attention matter that sullgage is deposited of being avoided pollution again at present.
