- Abstract:
- Shili River is an important inland river in downtown Jiujiang. Before remediation, the river was seriously polluted, and 7.20 km downstream river was determined as a black and odorous water body. The comprehensive treatment project of Shili River water environment mainly included source control, sewage interception, internal source control, ecological remediation and ecological water compensation. The black and odorous water was completely eliminated in Shili River through reconstruction of source community, construction and repair of the secondary pipe network and sewage interceptor sewer, construction of regulation and storage tank, construction of sewage treatment plant, ecological desilting, construction of water ecosystem, ecological water compensation and other engineering measures, and the main water quality indicators such as ammonia nitrogen, COD and DO all reached the class Ⅳ surface water standards. In addition, after the implementation of the project, COD at the outlet of the community sewage system increased significantly, the sewage treatment capacity increased greatly, the ecological benefits fully displayed, and good environmental and social benefits were achieved.
