摘要
针对抗生素工业废水极难处理特点,采用“微电解＋A20法＋絮凝沉淀＋生物滤池”组合技术处理以抗生素类制药废水为主的混合工业废水.实验结果表明,进水CODCr质量浓度235～667 mg/L,NH3-N质量浓度28.2 ～ 72.3 mg/L,TP质量浓度4.52～19.6 mg/L,色度为69～ 151倍,pH 6 ～9,设计流量30.0 L/h条件下,系统取得了良好的处理效果,其CODCr、NH3-N、TP和色度的平均去除效率分别达到90.0％、94.1％、97.9％和79.4％,出水CODCr、NH3-N、TP和色度等指标均达到《城镇污水处理厂污染物排放标准》（GB 18918-2002）一级A标准,该工艺处理效果稳定可靠,运营管理较简单.
According to the refractory feature of antibiotic industrial wastewater,the micro-elcetrolysis ＋ A2O ＋ flocculation ＋ biofilter method is used to treat antibiotic pharmacy-based mixed industrial wastewater.The results show that the treatment effect is good under the following conditions：235-667 mg/L of the CODCr concentration,28.2-72.3 mg/L of the concentration of NH3-N,4.52-19.6 mg/L of the concentration of TP,69-151 times of the chromaticity,6-9 of the pH and 30L/h of the design flow.The average removal efficiency of CODCr,NH3-N,TP and chromaticity can reach 90.0％,94.1％,97.9％ and 79.4％,respectively.The residual CODCr,NH3-N,TP and chromaticity in effluents achieve the first grade A standard of Municipal Wastewater Treatment Plant Discharge Standard （GB 18918-2002）.The treatment effect of this process is stable and reliable with easy management.
