昆明市区主要饮用水源水质分析

Water quality analysis of main drinking water source of Kunming

昆明市区主要供水水源为松华坝水库、柴河水库、大河水库。除柴河水库非汛期水质为Ⅱ类外,其余各时段的水库水质均为Ⅲ类,且3个水库各时段的营养状况均为中营养。建议采取划定水源保护区、加大水土流失治理力度、控制面源污染等措施保护水源。

The main drinking water sources of Kunming are Songhuaba reservoir, Chaihe reservoir and Dahe reservoir. Except the water quality of Chaihe reservoir is the class Ⅱ in dry season, the water quality of other reservoir in other period is the class Ⅲ. The three reservoirs are mesotrophic lakes. So we should designate sanitary zone of water source, control soil and water loss and non- point source pollution to protect water source.
