苍南县饮用水源地水库水质评价及污染防治对策

Water Quality Assessment and Pollution Control Measures of Drinking Water Source Site Reservoirs in Cangnan

概述了苍南县饮用水源地水库的主要类型和主要污染源,介绍了库区水质监测和评价的方法,并根据近3 a苍南县6个饮用水源地水库水质的监测数据,对库区水质进行了综合评价。结果表明:除十八孔水库水质持续恶化外,吴家园水库等5座水库水质指标基本稳定,均能够满足Ⅱ类水功能要求。针对库区的主要污染源,提出了水质污染的防治措施。

The main types and pollution sources of drinking water sources site reservoirs in Cangnan were summarized. The methods of monitoring and evaluating the water quality were introduced. On the basis of monitoring data of the drinking water quality from six source sites reservoirs in Cangnan in recent three years, the water quality in reservoirs were evaluated comprehensively. The results showed that the water quality of Shibakong reservoir progressively deteriorated, while that of the other five reservoirs were basically stable to meet the functional requirements of grade 11 water. According to the main pollution sources in reservoirs, the control measures of water pollution were put forward.
