The combined process,pretreatment-ASBR-two-stage SBR has been used for treating hydrosulfite waste-water. The experimental results show that the pretreatment can improve the biodegradability of wastewater. When anaerobic system COD sludge load is at the most 0.5 kg/(kg·d),and the two-stage SBR aeration time are 11 h and 8 h respectively,the COD removing rates of anaerobic and two-stage SBR can reach 69%and 97%,respectively,the COD total removing rate of the combined process can reach 98%,and the effluent water quality can meet the second grade of Integrated Wastewater Discharge Standard(GB 8978—1996).
