- 摘要:
- 烟台市小鱼鸟河位于烟台市郊区，流域范围涵盖农村、工业区和老城区，河流污染源复杂，整体环境质量较差。采取完善截污管网、河道清淤、河道基底修复等措施，对小鱼鸟河进行了系统性整治。综合治理后河道黑臭基本消除，水质得到根本性改善。因小鱼鸟河属于雨源型季节性河流，整治后河道断流情况较为突出，水体流动性下降，短期出现了水质反弹情况。通过对小鱼鸟河整治效果及长效管控情况分析，建议采取加强雨污分流、控制溢流污染、河道补源等措施，保障黑臭水体整治效果，实现整治后河道长制久清。
- 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.
