Abstract

The treatment of petrochemical wastewater by using suspended filler biofilm A/O process is introduced.The results show that the process has a high removal efficiency of CODCr 81 %、NH3 -N 94 %、TN 57 .3 % under the condi tio ns of HRT 8 h , R 100 %.The ef fluent quality is stable and conforms to the national permitted criterion , the characteristics of the process is studied and discussed on the basis of experiments to provide experimental basis for its application to petrochemical wastewater treatment .
