【摘要】 黑臭水体在我国水环境中非常普遍,且呈增多态势。黑臭水体导致河流生态系统破坏,严重影响了人们的生活及周围居民的健康。因此,黑臭水体的治理刻不容缓。以龙潭川为调查对象,检测了水体及底泥中重金属、COD、氨氮等主要指标,重点分析其黑臭水体的成因和机理,并根据龙潭川的实际情况提出了川内环保清淤,沿川雨、污水管线重新规划,水生植物修复川内黑臭水体,建设川内水生态、长效修复工程,建设河道补水工程,建设沿川两岸生态修复工程,建设水质保障的长效机制等治理方案。更多还原

【Abstract】 Black and odorous water body is very common in water environment in China,and has a developing trend. Black and odorous water body causes river ecosystem to be destroyed,seriously affecting people’ s lives and even endangering the health of the surrounding residents. Therefore,the treatment of black and odorous water body pollution is imperative and urgent. In this paper,the main targets of heavy metals,COD and ammonia nitrogen in water and sediment in Longtan River are examined. The causes and mechanism of black and odorous water body are analyzed,and some treatment schemes are put forward according to the actual conditions of Longtan River,such as environmental conservation clearing silt,replanning of rainwater and sewage pipelines along the river,black and odorous water body remediation by aquatic plants,construction of long-term water ecological rehabilitation projects,riverway water supplement projects,ecological rehabilitation projects on both sides along the river,and long-term mechanism of water quality safeguard.更多还原
