摘　　要：对南方沿海城市分流制排水管网的沉积物特征进行了分析。结果表明,研究区域的雨水和污水管道沉积物均未检测出苯并(a)芘、苯酚、氰化物、多氯联苯等常见有毒物质;公园绿地区的雨水管道沉积物中无机物、硫化物、全氮、石油烃(C_(10)~C_(40))、总磷含量都较其他区域要低;排水管道沉积物中的颗粒以0.05~2.0 mm的砂粒为主,而在公园绿地区粒径较小的粉粒和黏粒占比也较大,说明地表植被可以有效阻滞大颗粒物质进入排水系统;雨水管道沉积物中重金属含量排序为:工业区>居民区>公园绿地区;管道沉积物中的微生物以Christensenellaceae-R-7-Group、Acinetobacter(不动杆菌)和Desulfovibrio(硫化振动菌)为优势菌属。The characteristics of sediment from the separate drainage pipelines in southern coastal cities were analyzed.Common toxic substances such as benzo(a)pyrene,phenol,cyanide and polychlorinated biphenyls were not detected in the sediments from stormwater and sewage pipelines in the study area.The concentrations of inorganic matter,sulfide,total nitrogen,petroleum hydrocarbons(C_(10)-C_(40)),and total phosphorus in the sediment from stormwater pipelines of the park green area were lower compared to those in other regions.The particles in the pipeline sediments were mainly sand particles ranging from 0.05 mm to 2.0 mm,while the proportion of smaller particles such as silt and clay was also higher in park green area,indicating that surface vegetation effectively prevented large particles entering the drainage system.The descending order of heavy metals content in stormwater pipeline sediments was as follows:industrial area,residential area and park green area.The dominant bacterial genera in the pipeline sediments were Christensenellaceae-R-7-Group,Acinetobacter,and Desulfovibrio.
