| Abstract: | Hydrolysis+A/O+coagulation and sedimentation process has been used for treating acrylonitrile-acrylic fibre wastewater.When the influent COD concentration is below 850 mg/L,and HRT of hydrolysis tank and A/O system are more than 15 h and 65 h,respectively,the COD,NH3-N and SCN-concentration of the biologically treated effluents are less than 150 mg/L,10 mg/L and 0.5 mg/L,respectively.The effluent COD concentration,after being treated by coagulation sedimentation,is below 100 mg/L,and the cost of coagulant p... |
