摘要
崂山水库是青岛的重要饮用水源地之一,通过调查和分析崂山水库的富营养化状况,发现高锰酸指数较稳定,浓度低于3.5mg/L;氮、磷是主要污染因子。其中,氮浓度连续10年超过国家《地表水环境质量标准》Ⅱ类标准,磷可能是崂山水库初级生产力的限制因子。针对这些问题,提出应把控制入库污染物排放源及在水库水源保护区内的综合治理放在首位。
Laoshan reservoir is one of the major drinking water sources in Qingdao.This paper analyses water quality and estimates eutrophication of Laoshan reservoir.The result show that,CODMn is below 3.5mg/L,TN,TP is the major pollutant,which TN is higher than II standard of ＂Environmental quality standards for surface water＂,and P is limited factor of primary productivity.It is suggested that pollutant emission should be controlled and water source protection zones should be managed comprehensively.
