Research on the Removal Effect of Conventional Pollutants by Biological Aerated Filter
LIU Jian
Abstract：Biological aerated filter has been widely used in the field of sewage treatment.The concentrations of chemical oxygen demand,ammonia nitrogen,total nitrogen and total phosphorus in sewage are significantly reduced after treatment by biological aerated filter,the water quality is greatly improved,and the pollutant concentration reach the corresponding standard requirements.By collecting and monitoring samples of domestic wastewater from four sewage treatment plants using the biological aerated filter process,the concentrations of the above four pollutants in water were compared and analyzed.It was found that water temperature,load and other factors had obvious effects on effluent quality;from the perspective of pollutant removal efficiency,the removal efficiency of total nitrogen was relatively low compared with the other three pollutants;at the same time,the problems in the actual operation of biological aerated filter were summarized.It plays an active role in the popularization,engineering application and operation management of biological aerated filter in wastewater treatment.
