| Abstract: | There are plenty of pollutants,such as oils,phenol-cyanogen,ammonia nitrogen,etc,in coking waste water.It is introduced flow sheet,design & running parameter of air floatation and A/O(anaerobic/aerobic) bio-denitrification process for treatment of sewage from a coking plant.The design treatment capacity of the process was 65 m3/h.At present,the system runs steady,the treated water quality reachs scondary discharge standard of "Integrated Wastewater Discharge Standard"(GB 8978—1996). |
