Treatment of Chinese pharmaceutical manufacturing wastewater by iron carbon microelectrolysis-IC-AO process
As pharmaceutical manufacturing wastewater is characterized by high pollutants concentration and poor biodegradability,microelectrolysis-IC-AO process was adopted for its treatment.The operation results of the project showed that,the mass concentrations of COD,BOD5,SS,NH3-N and TP in Chinese pharmaceutical manufacturing wastewater decreased from 9437.5,1524.5,562.0,64.6 and 15.5 mg/L respectively to 285.0,86.0,48.3,15.0 and 1.5 mg/L respectively,the removal rates reached 96.98％,94.36％,91.41％,76.78％and 90.32％respectively.The effluent water quality was stable and met the requirement of grade 3 in GB 8978-1996 Com-prehensive wastewater discharge standard and the limiting value of the industrial park sewage treatment plant takeover standard.
