| Abstract: | The philosophy,process and main control requirement for biological denitrification process were introduced.Removal of NH3-N is the key to coking wastewater treatment by A2/O method.Using this method NH3-N concentration was reduced from 150-250 mg/L to less than 15mg/L.Effluent COD was kept at no more than 100 mg/L.The treated water can live up to class-II criteria specified in Integrated Wastewater Discharge Standard(GB8978-1996). |
