【摘要】 某制药公司通过化学合成法生产抗生素,产生高浓度有机废水,而且成分复杂难以降解。原有处理工艺为混凝+臭氧+厌氧水解+好氧+缺氧水解+CAST工艺,不能使该废水处理达标排放。基于废水的水质特点,采用Fe-C+Fenton+混凝+水解酸化+IC+A/O+BAF工艺处理该废水,并对原有构筑物进行了改造和扩建。运行结果表明,改造后出水各项指标稳定达到《化学合成类制药工业水污染物排放标准》(GB 21904—2008)。更多还原

【Abstract】 A pharmaceutical company produces antibiotics through chemical synthesis,and discharges high concentration,complex and refractory organic wastewater. The effluent of original treatment process of coagulation + O3+ anaerobic hydrolysis + aerobic + anoxic hydrolysis + CAST could not meet the discharging standard. Based on the characteristics of wastewater,combined process of Fe-C + Fenton+ coagulation + hydrolytic acidification + IC + A/O + BAF was adopted,and the original structure was reconstructed and expanded. The operation result showed that the effluent indexes stably met the Discharge Standard of Water Pollutants for Pharmaceutical Industry Chemical Synthesis Products Category( GB21904-2008).更多还原
