厦门埭头溪河道水质调查及生态对策

Investigation of Water Quality and Countermeasures of Ecological Protection for Daitou Creek in Xiamen

针对厦门埭头溪的生态环境问题现状,进行了深入调查研究,分析了埭头溪河道监控断面主要水质指标溶解氧(DO)、高锰酸盐指数(CODMn)、化学需氧量(CODCr)、五日生化需氧量(BOD5)、氨氮(NH3-N)、总磷(TP)和总氮(TN)的超标率,计算了主要污染源的CODCr、NH3-N和TP排放量,剖析其产生的主要原因和治理难点。从政府管理和工程措施两个方面对河道生态环境治理提出了有针对性的对策与建议,可为河道生态环境治理工作提供技术支撑和应用借鉴。

Ecological environment problems of Daitou Creek were deeply investigated and studied.The over-limit rate of key water quality indicators were analyzed,such as dissolved oxygen(DO),potassium permanganate index(CODMn),chemical oxygen demand(CODCr),five-day biochemical oxygen demand(BOD5),ammonia(NH3-N),total phosphorus(TP)and total nitrogen(TN).Primary pollution sources of CODCr,NH3-N and TP emission were determined,and the cause of ecological environment problems and their management difficulties were analyzed synthetically.Specific government management policy and engineering treatment measures were put forward for comprehensive improvement ecosystem environment in Daitou Creek,which could provide technical support and application reference for the ecological environment management of creek.
