The ammonia nitrogen level in the aerobic tank is high, and the water in the secondary sedimentation tank is turbid with poor water quality
The main reason for high ammonia nitrogen levels in the effluent may be poor control of DO; low water temperature can also lead to a reduced effectiveness in removing ammonia nitrogen. 1. Increase aeration volume, 2. Recirculate the effluent. 3. Severe sludge aging leads to a decrease in treatment efficiency.
