苏州城区河道水质现状分析

Current water quality analysis of the river in the Suzhou urban area

跟踪了苏州城区内27个重点河流断面半年的监测数据,重点监测了溶解氧、氨氮、总磷、高锰酸盐指数4个富营养化指标。计算了各种污染物单因子污染指数、主要污染物分担率和平均污染指数,并对水质污染程度进行综合评价。结果表明,在苏州城区河道的27个重点监测断面中,大部分属于中度污染,水体的主要污染物为溶解氧、氨氮和总磷。分析了可能导致城区河道水体污染的主要原因,并提出治理建议。

Monitoring data of 27 key river sections of suzhou city within half a year＇s were racked , mainly including the dissolved four eutrophication index of oxygen, ammonia nitrogen, total phosphorus and potassium permanganate index. Various pollutants are calculated by single factor pollution index, the main pollutant and share rate of average pollution index, and presented a comprehensive evaluation of water quality pollution degree. The results showed that most of the 27 key monitoring section of fiver in suzhou city are belonging to a moderate pollution, and the main pollutants of water are dissolved oxygen, ammonia and total phosphorus . Analyzed the main causes which leading to water pollution of urban river, proposed suggestions for management.
