风雨湖水体污染监测研究

摘要

The CODMn, pH value ,total bac terial count,total coliform group and heavy metal ion of the water body of the F engyu Lake were determined.The results showed that this lake was greatly pollute d. The average values of these monitored items were:CODMn 24.68 mg.L－1，pH 6.2,the total bacterial count 3.0×103／mL, and the nu mber of total coliform group 1.60×104／L. The results also showed that this l ake wasn't polluted by heavy metal ion. Some suggestions were proposed to protect the water quality.%选用CODMn、pH值 、细菌总数、 大肠菌群和重金属离子等水质指标对风雨湖水体进行了污染监测。结果表明，水体已被严重 污染，属生活污水造成的有机污染型。CODMn平均26.68 mg.L －1，pH值平均6.2，细菌总数平均3.0×103个.mL－1，总大肠菌群数平均 1.6×104个.L－1。主要污水源和水体的重金属离子均未超标。对污染的可能原 因及防治对策进行了讨论。
