摘要
对江苏省有代表性的88个水厂进行调查,并对其中30个水厂的水质及净水剂进行分析。结果提示:50％的水厂在防护范围内有污染源存在,其中上下游均有污染者占36％,工业废水排放口与取水口最近距离为5m,最大排污量为每日1百万吨,水源水质受到明显污染。分析42份净水剂,除5份固体碱式氯化铝能达到四川省标准外,其它37份均不能达到国内外标准。30项水质分析,有9项超标,浑浊度超标率高达53.33％,大肠菌群超标率为10％。目前我省部分水厂水质尚不能全部符合国家生活饮用水水质标准。
Eighty-eight waterworks in Jiangsu province were investigated. Water quality and coagulant of thirty waterworks were analyzed. Results showed that:50% waterworks had pollution sources in their protection zone, 36％ of then had pollution in both upper and lower reaches. The exit of industry waste water is only five meters away from water intake. Maximal draining sewage ate 10~7 tons every day. Source of water is obviously polluted. There were 42 coagulant samples analyzed. Among them five reached the provincial standard of Sichuan for the level of solid alkaline aluminum chloride. All the athers did not satisfy the national or internationalstand ards.
