摘　　要：煤炭型城市河流污染评价与溯源是国内外学者关注的热点问题。以典型的煤炭型城市宿州市城区河流沱河与新汴河为研究对象,测定水体中污染物指标化学需氧量(COD)、总磷(TP)、总氮(TN),氨氮(NH_(3)-N)和高锰酸盐指数(COD_(Mn))等指标,利用单因子水质标识指数法、相关性分析等方法对比2条河流的水质与污染来源。结果表明:(1)沱河与新汴河水体中TN质量浓度较高,NH_(3)-N与TP所对应的水质类别全部符合安徽省水功能区划对应的标准,2条河流的COD与COD_(Mn)质量浓度均存在不同程度的超标。(2)新汴河中NH_(3)-N与TP质量浓度存在极显著正相关(r=0.701,P<0.01),有着相似的污染源,主要受河流周边农田肥料使用的影响;沱河中TN与COD_(Mn)、NH_(3)-N质量浓度之间均存在极显著正相关(r分别为0.637和0.555,P<0.01),NH_(3)-N与COD_(Mn)质量浓度之间存在显著正相关(r=0.418,P<0.05),而NH_(3)-N与TP质量浓度之间存在显著负相关(r=-0.469,P<0.05),说明氮污染物与磷污染物存在着不同的污染来源,氮污染分布可能是受煤炭开采矿井废水排放影响较大,磷污染分布可能是受居民生活洗涤污水排放的影响较大。研究结果可为人类活动对煤炭型城市城区河流污染分布的影响机制提供理论参考。The assessment and source identification of river pollution in coal cities is highly concerned by researchers at home and abroad.This study focused on Tuohe River and Xinbian River in Suzhou City which is a typical coal city.The chemical oxygen demand(COD),total phosphorus(TP),total nitrogen(TN),ammonia nitrogen(NH_(3)-N)and permanganate index(COD_(Mn))in two rivers were measured.The water quality and pollution sources between two rivers were comparatively revealed based on single factor water quality identification index and correlation analysis.The results show that the contents of TN in Tuohe River and Xinbian River were relatively high while the water quality levels of NH_(3)-N and TP met the corresponding standards of Water Functional Division in Anhui Province.However,the concentrations of COD_(Mn) and COD exceeded the standard.NH_(3)-N and TP concentrations in Xinbian River showed a significant correlation(r=0.701,P<0.01),indicating similar pollution sources which were mainly affected by the use of fertilizer in farmland around the river.TN concentrations presented the significant positive correlation with COD_(Mn) and NH_(3)-N in Tuohe River(r=0.637 and 0.555,respectively,P<0.01).NH_(3)-N showed a positive correlation with COD_(Mn)(r=0.418,P<0.05)but a negative correlation with TP(r=-0.469,P<0.05).The correlation between pollutants in Tuohe River indicated that there are different pollution sources of nitrogen and phosphorus pollutants.The distribution of nitrogen pollution in Tuohe River was probably affected by the discharge of coal mining wastewater while the discharge of domestic washing sewage caused the accumulation of phosphorus pollutants.This study can provide a theoretical reference for the impact mechanism of human activities on the distribution of urban river pollution in coal cities.
