- Abstract
In order to understand the extent of the effect of urban surface runoff on the microbial contamination indicators of Zhuxi river in Three Gorges Reservoir. Bridge crane, Shahe Town district offices, Wanhu Village, Gold Coast of Tianxian lake and Tianxian lake Plaza were selected as sampling points from which 5 surface water samples were collected on 6 and 12 month in 2013. Indicator organisms indexes including bacteria! CFU), total coliforms(TC), fecal coliform(FC) and fecal streptococcus (FS) in water samples were analyzed, while the water turbidity of these 5 samples from Zhuxi river were tested. The result showed that the concentrations of CFU and FC were higher in 5 surface runoff samples of Zhuxi river, the difference was significant between winter and summer, the concentrations of indicator organisms in samples 3 were relatively higher, and the correlation of indicator organisms was obvious. The runoff functional categories of 5 samples were beyond standard Grade V, failing to meet the urban pollutant emission standards. The water turbidity of Zhuxi river in summer was higher than that in winter, and the turbidity of sample 3 in the summer was the highest. The water turbidity of Zhuxi river was consistency with the concentration of indicator organisms in urban surface runoff.
