【摘要】 抗生素工业废水难处理,特别是以抗生素工业废水为主的混合工业废水经二级生化处理后的尾水.有鉴于此,本文用MicroFA四相催化氧化技术对二级生化出水进行深度处理,发现效果好,其FeSO4和H2O2控制投加量分别为6.5mg/L、5.5mg/L,对重铬酸盐指数(CODcr)、TP的平均去除效率分别为50.48%、94.71%,出水CODcr、TP能达到《污水综合排放标准》(GB8978-1996)的一级排放标准,甚至可达到《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准.该工艺一次性投资较高,但运营管理较简单,处理效果稳定可靠,运行成本0.92元/吨、相对合理.该工艺为难生物降解的抗生素类制药为主的混合工业废水二级出水的深度处理提供了新途径.更多还原

【Abstract】 Because of the refractory feature of antibiotic industrial wastewater,especially the effluent of the mixed industrial wastewater after the secondary biochemical treatment,the MicroFA four-phase catalytic oxidation technology is applied to treat the above mixed industrial wastewater and achieves good treatment results.The dosages of FeSO4 and H2O2are 6.5mg/L and 5.5mg/L,respectively,and the mean removal rates of CODcr and TP are 50.48%and 94.71%,respectively.The CODcr and TP in effluent achieve the first grade of Comprehensive Discharge Standard for Sewage(GB8978-1996)and even the first A grade of Pollutant Discharge Standard for Urban Sewage Treatment Plant(GB18918-2002).The one-time investment of this method is high,but the operation is simple,the treatment effect is stable and reliable,and the operation cost is reasonable(0.92yuan/t).This technology has a bright future in the advanced treatment of effluent of secondary biochemical treatment for refractory antibiotic industrial wastewater.更多还原
