According to a great deal of experimental findings and theoretical analysis, when the COD of inlet is 1 000-1 200 mg/L, NH3--N is 200~250 mg/L, the periodic time of operation is 24 h, the aeration time is 16 h and the...According to a great deal of experimental findings and theoretical analysis, when the COD of inlet is 1 000-1 200 mg/L, NH3--N is 200~250 mg/L, the periodic time of operation is 24 h, the aeration time is 16 h and the sludge density is 5 000-7 000 mg/L, COD of outlet is 150-200 mg/L, NH3--N is less than 25 mg/L, the volume load of COD and NH3--N remove 0.50 and 0.12 kg/(m3od) respectively. Meanwhile, studied the influence of various crafts parameter change on the treating effect and absorbing the yielding water of the SBR reactor with pulverized coal ash for improving the removing effect of COD and chromaticity further.展开更多
