煙臺市小魚鳥河整治效果及長效管控分析與對策
- Title:
- Regulation Effect and Countermeasures of Longterm Management of Xiaoyuniao River in Yantai City
- 摘要:
- 煙臺市小魚鳥河位于煙臺市郊區(qū),流域范圍涵蓋農(nóng)村、工業(yè)區(qū)和老城區(qū),河流污染源復(fù)雜,整體環(huán)境質(zhì)量較差。采取完善截污管網(wǎng)、河道清淤、河道基底修復(fù)等措施,對小魚鳥河進行了系統(tǒng)性整治。綜合治理后河道黑臭基本消除,水質(zhì)得到根本性改善。因小魚鳥河屬于雨源型季節(jié)性河流,整治后河道斷流情況較為突出,水體流動性下降,短期出現(xiàn)了水質(zhì)反彈情況。通過對小魚鳥河整治效果及長效管控情況分析,建議采取加強雨污分流、控制溢流污染、河道補源等措施,保障黑臭水體整治效果,實現(xiàn)整治后河道長制久清。
- 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.
