- Abstract:
- The treatment of black and odorous water body is a long-term and arduous task, and the treatment of black and odorous water in old urban areas is particularly difficult due to incomplete drainage systems, complex water pollution causes, and inadequate supervision mechanisms and other reasons. Combined with the characteristics of old urban areas and the current requirements of the black and odorous water treatment as well as the sewage system quality and efficiency improvement, this paper systematically recommends the idea of treating the black and odorous water body and the method of establishing long-term treatment system. Taking an inland river of a coastal city in South China as an example, this paper introduces the pollution causes of black and odorous water body in details, and the treatment scheme of sources controlling and pollution interception, control of endogenous pollutants, watershed ecosystem conservation and rehabilitation, and flowing water replenishment. This study may provide a reference for the treatment of black and odorous water body in other old urban areas.
