Using sequencing batch reactor(SBR)to treat phenol-cyanogen wastewater from coking plants has been conducted. The effect of aeration time and sludge loading are discussed. Experimental results show that: when mixed liquid suspended solid is 4 g/L,sludge loading is 0.15 kg/(kg·d)and aeration time is 4 h,the removal efficiency of COD reaches 86.6%,that of phenol reaches 99.7%,cyanogen reaches 95.9%. It has better disposal result of NH3 - N if changing this running process of SBR.
