摘要:
针对常见的高锰酸盐指数(CODMn)、五日生化需氧量(BOD5)、氨氮(NH3-N)、总磷(TP)、总氮(TN)5项水质指标,运用综合污染指数法和单因子评价法,分别对2015—2018年阳澄湖、七浦塘及主要河网水质数据进行对比分析。结果显示,阳澄湖区整体水质由重污染转化为污染,主要超标因子为总氮,水质类别已从劣V类转变为V类。七浦塘整体水质除总氮指标仍为V类外,其他4项指标均为Ⅱ、Ⅲ类水平。其他河网主要河流2018年相较2015年的水质类别均有改善,七浦塘调水引流工程对于提高阳澄湖区水体流动性,改善阳澄湖及周边河网水质有重要作用。
Abstract:
Aiming at the five water quality indicators of common permanganate index(CODMn), five-day biochemical oxygen demand(BOD5), ammonia nitrogen(NH3-N), total phosphorus(TP)and total nitrogen(TN), the comprehensive pollution index method and single-factor evaluation method were used to compare and analyze the water quality data of Yangcheng Lake, Qiputang River and major river networks from 2015 to 2018. The overall water quality in Yangcheng Lake area had changed from heavy pollution to pollution, the main excess factor was total nitrogen, and the water quality category had changed from inferior V category to V category. The overall water quality of Qiputang River, except for the total nitrogen index was still still in category V, and the other four indicators are all in category II and III. Compared with 2015, the water quality of other major rivers in the river network has improved in 2018. It was shown that Qiputang water diversion project was of great work to improve the water mobility in Yangcheng Lake District and the water quality of the surrounding river network.
