%X High strength ammonia sludge dewatering water was treated by a A/O-CSTR process.The ammonia content was about 350 mg/L.The carbon source for denitrification was deficient due to the ratio of C/N was below 1.0.Ammonia of reject water was nitrified in A/O reactor and then reduced to nitrogen gas by denitrifiers in CSTR,with using primary sludge as additional carbon source.The start-up of partial nitrification was investigated.The effects of the effluent recycle on partial nitrification and nitrogen removal efficiency were also studied.The results shows that the system has a good performance in total nitrogen removal.The nitrite accumulate ratio was improved and maintained above 90%.The primary sludge were successful utilized as the carbon source for stable denitrification.The recycle of CSTR effluent benefited nitrogen removal efficiency.As the recycle ratio was 200%,total nitrogen removal efficiency was more than 85%.
