- Abstract:
- Xiaoyuniao River is located in the suburb of Yantai City, covering rural areas, industrial areas and old urban areas. The pollution sources of the river are complex, and the overall environmental quality is poor. Some measures such as improving the sewage interception pipe network, dredging the river and repairing the river channel base were taken to systematically regulate the pollution of Xiaoyuniao River. Through comprehensive treatment, the black and smelly conditions of the river were basically eliminated, and the water quality was fundamentally improved. Because Xiaoyuniao River was the rain source type seasonal river, after the regulation the situation of the river current breaking came to be more and more prominent, the water body fluidity dropped, and the water quality rebounded in a short time. Through the analysis of the regulation effect and long-term management of Xiaoyuniao River, this paper suggested that measures should be taken to strengthen the separation of rainwater and sewage, control the rainwater overflow pollution, and replenish the source of the river, so as to ensure the regulation effect of the black and smelly water body and realize the long-term clearing of river channel after regulation.
