The influence of pH value and adding pulverized fuel ash on the SBR treatment system

摘要

According to a great deal of experimental findings and theoretical analysis,when the COD of inlet is 1 000～1 200 mg/L, NH_3-N is 200～250 mg/L, the periodic time ofoperation 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, NH_3-N is less than 25 mg/L, the volume load of CODand NH_3-N remove 0.50 and 0.12 kg/(m^3·d) respectively.Meanwhile, studied the influenceof various crafts parameter change on the treating effect and absorbing the yieldingwater of the SBR reactor with pulverized coal ash for improving the removing effect ofCOD and chromaticity further.
