城市黑臭水体治理进展及水利措施研究

Research on the Progress of Urban Black-odorous Water Governance and Water Conservancy Measures

水体黑臭是经济社会快速发展和城镇化进程不断快速的产物,且部分城市仍遭遇黑臭水体“治理反复、反复治理”的困境。目前,城市黑臭水体治理大多从生态学、水污染治理等角度来开展,忽视了水利措施的重要作用。系统地梳理城市黑臭水体成因、治理进展及其常见的治理措施,并结合黑臭水体治理中存在的水利技术需求,研究提出城市黑臭水体治理过程中所需的水利措施,包括生态流量保障、河道整治、河湖水系连通、岸坡修复等水利措施与技术,以期为城市黑臭水体治理脱困提供技术参考。

Black-odorous water can be said to be one product happening in the course of increasing economic and social development and accelerating urbanization process.Therefore,some cities have still been suffering from the dilemma of“Governance Repetition and Repetitive Governance”of black-odorous water.Nowadays,most of the current cases of governance for black-odorous water have been carried out from the following angles,inclusive of ecology and water-pollution control,without putting more eyes on the important role of various water-conservancy measures.Systematically sort out actual causes and progresses of urban black-odorous water,as well as actually-adopted governance measures therein,with combination of specific water-conservancy technical requirements existing in the course of governing blackodorous water,this paper makes a series of researches and finally proposes specific water-conservancy measures required in the practical governance of urban black-odorous water,including ensuring ecological flows,river regulation,inter-connecting river-system networks,restoring bank slopes and other water conservancy measures and technologies for the purpose of providing certain technical references for the subsequent governance of urban black-odorous water.
