厦门杏林湾水库截污效果分析及防控对策

Assessment of Water Quality after Sewage Interception and Water Pollution Control in Xinglin Bay Reservoir

摘要: 利用杏林湾水库水质监测资料，用超标分类评价法对杏林湾水库截污后水质变化进行评价。结果表明，截污后的杏林湾水库水质指标DO、COD_Mn、BOD₅、NH_3-N和TP总磷都处于Ⅲ类以上水平，但TN仍处于劣Ⅴ类，常年处于严重污染状态。调查分析污染的主要原因为城镇生活污水及农业面源污染，并提出水库水质改善提高的措施。

Abstract: Based on the monitoring data of water quality in Xinglin bay Reservoir, non-compliance category evaluation method was applied to evaluate the changes of water quality after sewage interception. The results showed that the water quality indexes of DO, COD_Mn, BOD₅, NH_3-N and TP were all above class III level, but the TN was below class V level. Investigation indicated that the main pollution reasons included urban domestic sewage and agricultural pollution. Appropriate measures should be taken to restore and protect water quality of the Xinglin bay Reservoir.
