泰安市饮用水源黄前水库水质监测与评价

 以泰安市地面集中式生活饮用水水源———黄前水库为对象,根据《国家地面水环境质量标准》(GB3838—2002),采用目前国内较常用的单因子评价法,对库区2001—2002年期间水质27项指标进行连续监测和评价。结果表明:高锰酸盐指数、化学需氧量、总磷、总氮这4项为水库水质的主要污染物,汛期水质状况较非汛期差,库中水质较坝前好。在此基础上分析其原因,提出相适宜的解决办法,为有针对性地防治水污染,保护地表饮用水源,进一步改善水质,优化水源管理,保障人民健康和维护良好的生态系统提供科学依据。

Monitoring and Appraising on Water Quality of Huangqian Reservoir for Drinking Water of Taian

Based on the continuous monitoring of 27 indexes in Huangqian Reservoir, the drinking water source of Taian city from 2001 to 2002, the water quality was appraised according to the environmental quality standards for surface water(GB3838-2002) and single gene standard which were rather common used in China. The results showed that the main factors influencing the reservoir's water quality were permanganate, chemistry needed oxygen capacity, the total phosphorus and nitrogen, the water quality in flood season was worse than that in non-flood season, and the water quality of storeroom was better than that of dam-former. On the base of those, the reasons were analyzed, the corresponding settlement measures were put forward, and the scientific basis were offered to protect the drinking water source pointedly, improve water quality further, and optimize water management.
