Abstract: Taking pH, WT, DO, SD, BOD5, CODCr, CODMn, TOC, NH3-N, NO3-N, TN, Chl-a, DP and TP as the primary parameters, four medium or small creeks in Shanghai Taopu industry area are chosen as research rivers to evaluate the water quality, analyze temporal variation of water quality and identify pollution sources, by using analysis method such as principal component analysis, comprehensive pollution index, comprehensive nutritive index, organic pollution index and comprehensive water quality identification index. The research results indicate that Gongye River was the most polluted river in the four rivers, followed by Xiaozhai River and Zhangjin River, and Hongqi River was the best. TN and TP were the primary pollution parameters. DP was the main composition of TP, and NH3-N is the main composition of TN. In industry area, pollution control of small malodorous rivers should focus on source control, and take the integrative measurements like "source control and retention".

Key words: water quality, medium and small creek, index evaluation, malodorous river, monthly dynamics
