[/b][size=9.0pt]Experimental study on removing nitrogen and phosphorus from simulated wastewater by algae bio-film under the continuous light intensity 3 500 lx was carried out. The results showed that the effect of removing nitrogen and phosphorus by algae bio-film was remarkable, removals of total phosphorus[/size][/font][font=宋体]，[/font][size=9.0pt][font=Times New Roman]total nitrogen[/font][/size][font=宋体]，[/font][size=9.0pt][font=Times New Roman]ammonia and COD were 92.88%, 88.59%,93.49% and 94.97% ,respectively; Meanwhile, the simulated wastewater in the system after six days of treatment, total phosphorus, total nitrogen,ammonia and COD four terms were in line with the “Discharge standard of pollutants for municipal wastewater treatment plant” (GB 18918[/font][/size][font=宋体]－[/font][font=Times New Roman][size=9.0pt]2002), a standard B corresponding standard terms.[/size][size=10.0pt][/size][/font]
