Abstract

The project example of pre-denitrification biological aerated filter(BAF)for treatment of campus domestic sewage was introduced.The operation results show that the removal rates of COD,NH 3-N,TN and TP are 83.6% to 90.6%,96.7% to 97.8%,63.8% to 73.3% and 73.9% to 74.0 % respectively.The nitrogen and phosphorus removal effect is good.The effluent quality meets Standard for Domestic Miscellaneous Water Quality(CJ/T 48-1999)and Reuse of Urban Recycling Water —Water Quality Standard for Urban Miscellaneous Water Consumption(GB/T 18920-2002).
