摘要
为了解磁湖周边污染情况,分别在2018年9月和12月通过对磁湖湖滨带8个点位进行取样监测,运用模糊数学综合评价法,分析了各点位氨氮(NH3-N)、总氮(TN)、总磷(TP)、溶解氧(DO)、五日生化需氧量(BOD5)、化学需氧量(CODCr)、高锰酸盐指数(CODMn) 7项指标。结果表明,磁湖南半湖和北半湖水质差异性较大,南半湖水质相对较差,需要重点加强对磁湖南半湖污染防治的监督和管理。
In order to ascertain the pollution sources of Cihu Lake, water samples from 8 monitoring points of Cihu lakeside were monitored in September and December 2018. 7 indicators,including ammonia nitrogen(NH3-N), total nitrogen(TN), total phosphorus(TP), dissolved oxygen(DO), 5-day biochemical oxygen demand(BOD5), chemical oxygen demand(CODCr) and permanganate index(CODMn), were analyzed using the fuzzy comprehensive evaluation method. The results showed that the water quality of the south bank of Cihu Lake was quite different from that of the north bank, with more serious pollution in the former. It is necessary to strengthen the supervision and management of the pollution prevention and control of the south bank of Cihu Lake.
