The concentration of total nitrogen (TN) and total phosphorus (TP) in river water declined after pouring into <i>Chlorella</i> sp. and <i>Scenedesmus</i> sp., it was indicated that the <i>Scenedesmus</i> sp. had respective advantage in removing nitrogen (86% removal rate) and <i>Chlorella</i> sp. in removing phosphorous (95% removal rate). The algae community composition showed extreme sensitivity to change in the joint of the <i>Scenedesmus</i> or <i>Chlorella</i>, respectively, the lower diversity and higher dominance of algae can be observed in <i>Scenedesmus</i> group, there existed an opposite tendency in <i>Chlorella</i> group. The results demonstrated that the high potential of using <i>Chlorella</i> sp. and <i>Scenedesmus</i> sp. for nutrient removal from riverwater. %K Nutrient Removal %K Algae Community %K Chlorella %K Scenedesmus %K Eutrophication %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=87309
