For elucidating the effective management for nutrients removal by the phytoplankton growing at the effluents of night soil and sewage treatment plant, the dilution rates, physical operation conditions and duration of culture were defined. For nutrients removal from effluent of night soil treatment plant, lower the dilution was better, and Scenedesmus sp. was dominant. For removal from the effluent of sewage treatMent plant, the proper operation conditions were 50% of dilution rate, stirring and 2 days culturing. With these conditions, the removal rate of TKN was 88%, DIP$70{sim}80%$ and the chlorophyll concentration reached at $1,300;mg/m^3$ chlorophyll a concentration. the variation of chlorophyll a was highly corrrlated with ammonia ($r^2;=;0.96$) and DIP ($r^2;=;0.92$).
