摘要
以秦皇岛市地表饮用水源地的监测数据为基础,本研究采用综合污染指数为评价指标,对2011-2015年秦皇岛市石河水库、桃林口水库、洋河水库的环境质量现状进行评价,分析了水质营养状态和变化趋势。分析结果表明,石河水库、桃林口水库、洋河水库水质都为尚清洁;地表水饮用水源地富营养化程度均为中营养,饮用水源地水质均达标。这就为有针对性地保护饮用水源,进一步改善水质,优化水源管理提供了科学依据。
According to the monitoring data from 2011 to 2015 in Qinhuangdao city, the nutritional status and change trend of surface drinking water quality were analyzed. The comprehensive pollution index was used as the evaluation index to evaluate the environmental quality status of shihe reservoir, taolinkou reservoir and yanghe reservoir from 2011 to 2015 in Qinhuangdao city. The results show that the water quality of shihe reservoir, taolinkou reservoir and yanghe reservoir is clean. The eutrophication degree of surface drinking water is medium nutrition, and the water quality of drinking water source conforming to standard. It provides scientific basis for protecting drinking water source, improving water quality and optimizing water source management.
