AO-SBR process was originally carried out to treat organic amine wastewater in Jiangshan Chemical,but there were many problems,such as limited handling capacity,no-reaching standards and high disposal cost.It is determined to use hybrid anaerobic-chemical precipitation-multiplestage aerobic process to reform.Through more than 100 days' commissioning,first-stage project has run normally.Average removal rate of COD in hybrid anaerobic reactor is 51.55%,removal rates of ammonia-nitrogen of pre-aeration tank are 97.97% after normal operation.It is guaranteed TN that flow into aerobic tank is below 120mg/L,the effluent COD,ammonia and BOD5 is 365.6mg/L,37.2mg/L,43.5mg/L respectively,removal rate of COD and BOD5 in integrated system can reach to 90.8%,97.0%.The effluent meets the design requirements.Reformed process has good prospects for application.
