1.the stripped sour water is treated by DAF,sludge(combines moving bed biofilm and activated sludge ), filter by MBR system, and supply to cooling tower as part of make-up water. 2.the recirculation flow of the mixed liquor is about 3.5Q, to meet the MLSS 2,500~3,500 ppm.the DO is 3~4 ppm; pH 6.5~7.5. 3.the influent COD 500~800 ppm, NH3-N 2~40 ppm,TKN 15~80 ppm, NO2-N and NO3-N ~0 ppm. 4.the effluent COD 15~40 ppm, NH3-N 10~50 ppm,TKN 15~50 ppm, NO2-N and NO3-N ~0 ppm.
