摘　　要：选取太浦河干流沿岸6个代表性取样点进行取样,分别测定特征指标锑以及溶解氧、BOD、高锰酸盐指数、总磷、总氮、氨氮等指标,分析其上下游污染物浓度分布规律,从而得出研究区内太浦河水环境现状及水质结果。太浦河沿线锑浓度自太浦闸至黎里东大桥呈上升趋势,自黎里东大桥至下游练塘大桥呈平缓下降趋势,锑浓度最高点位于黎里东大桥为2.13μg/L;溶解氧浓度自太浦闸处沿下游逐渐下降,水质变差;高锰酸盐指数先上升后下降,至黎里东大桥附近浓度达到最大值4.18 mg/L;氨氮浓度规律与高锰酸盐指数相似,至芦墟大桥浓度达到最大值0.315 mg/L;总磷、总氮浓度沿程整体呈明显上升趋势,至芦墟大桥附近达到最高,总磷为0.086 mg/L,总氮1.25 mg/L。丰水期研究区内太浦河特征污染物锑浓度基本控制在2μg/L左右,符合生活饮用水水质标准;丰水期太浦河指标均达到或优于Ⅲ类水标准,溶解氧可达Ⅰ类,氨氮及总磷可达Ⅱ类;太浦河水质综合评价类别均为Ⅲ类。In order to study the current situation of the water environment and evaluate the water quality in the section from Taipu Gate to Liantang Bridge(demonstration section)of the Taipu River during the rainy season.This paper selected six representative sampling points along the main stream of the Taipu River,and measured the antimony,dissolved oxygen,BOD,permanganate index,total phosphorus,total nitrogen,ammonia nitrogen respectively.These date was used to analyze the distribution law of pollutant concentration among the upstream and downstream of the river,which was the basis of the environmental status and water quality results of the Taipu River during the study area.The results show that the concentration of antimony has a rising trend from the Taipu Gate to the Lilidong Bridge,while has a gentle downward trend from the Lilidong Bridge to the downstream Liantang Bridge.The highest concentration of antimony was 2.13μg/L at the Lilidong Bridge;The concentration of dissolved oxygen gradually decreases along the downstream from the Taipu Gate,which was the reason that the water quality becomes worse.The permanganate index has a rising trend from Taipu Gate to the Lilidong Bridgefirst and then decreased,The permanganate index concentration reached 4.18 mg/L at the Lilidong Bridge.The law of ammonia nitrogen concentration was similar to the permanganate index,which reached the maximum value of 0.315 mg/L at Luxu Bridge.The concentration of total phosphorus and total nitrogen increased significantly along the route,reaching the highest near the Luxu Bridge,the total phosphorus was 0.086 mg/L and the total nitrogen was 1.25 mg/L.It can be concluded that the concentration of antimony was basically controlled at about 2μg/L during the wet season,which conforms to the standard of drinking water quality.The indicators of the Taipu River reach or exceed the ClassⅢwater standard during the wet season.The comprehensive assessment of water quality of Taipu River is classified as ClassⅢ.
