%X Filamentous green algae dominated treatment system was set up to remove contaminants from polluted urban river water under lab conditions. Experiments show that TP is decreased up to 50%, associated with 72% removal of TSS. The removal efficiencies of soluble species, PO3-4 and NH+4-N, are up to 90% and 85% respectively. Under heavily polluted conditions (TP>3.0 mg·L-1, TN>22.0 mg·L-1), the average removal efficiencies of TP and TN are 89% and 45% respectively, while under light polluted conditions (TP<0.50 mg·L-1, TN<10 mg·L-1), the average effluent concentration of PO3-4 and NH+4-N are well below 0.1 mg·L-1 and 2.0 mg·L-1 respectively. During the experiments, the biomass of filamentous green algae is increased significantly (38.78%), and at the same time a large number of unicellular Chlorophytes and Cyanophytes species are occurred on the interior wall surface of experimental fertility. The maximum biomass occurs at the highest concentration of DO.
