摘　　要：论文考察了铁-炭微电解技术对某制药企业废水处理站二级生物处理出水的深度处理效果,以及对难降解生产废水和混合生产废水的预处理效果。结果表明:铁-炭微电解对废水处理站二级生物处理出水的TOC去除不明显,但使废水可生化性显著提高;对排放难降解污染负荷的生产废水的TOC去除率高于30%,其中难生物降解组分与可生物降解组分得到同比例去除。物料衡算结果表明,对小水量、高浓度、难降解的生产工段废水进行铁炭微电解预处理,污染物去除效果明显优于混合生产废水。Pollutant removal performance of the iron-carbon micro-electrolysis technology was studied when the technology was used to treat biological treated effluent,the mixed processing wastewater and wastewaters from five processing units that were main contirbutors to the refractory COD load.Results show that iron-carbon micro-electrolysis removes little TOC from the biological treated effluent,but notably improves the wastewater biodegradability.More than 30 % of TOC is removed from the processing unit wastewater,in which the removal rate of refractory components is equivalent to the biodegradable components.Material balance calculation reveals that pretreatment of the wastewaters from the five processing units can remove much more organic pollutants than pretreatment of the mixed processing wastewater.
