摘　　要：高浓度制药废水组成复杂、色度深、成分差异大、B/C比值低、有机污染物种类多且浓度波动大。臭氧-芬顿法处理废水具有操作简单、处理效率高的优势。本文采用该方法对制药废水处理工艺进行L_(25)(54)正交优化实验,分析pH,O_(3)流量q、COD与H_(2)O_(2)质量比m,Fe^(2+)与H_(2)O_(2)摩尔比n等4种影响因素对废水COD去除率和可生化比B/C的影响。研究发现,当pH=3.00,q(O_(3))=9.0 g/h,m(COD/H_(2)O_(2))=1/2,n(Fe^(2+)/H_(2)O_(2))=1/8时,废水可生化性指标B/C由0.075提升至0.533,极大地改善了废水可生化性,为后续的生化处理降低了难度,为企业废水处理提供了参考。High concentration pharmaceutical wastewater with complex composition,color,composition differences,poor biodegradability,low B/C ratio,kinds of organic pollutants and concentration fluctuations.The ozone-Fenton method has the advantages of simple operation,high processing efficiency,which was adopted for the L_(25)(54)of pharmaceutical wastewa-ter orthogonal experiment,where a comparative analysis of the four the influence factors on the removal rate of COD and B/C ratio.The research shows that when the pH is 3.00,q(O_(3))is 9.0 g/h,m(COD/H_(2)O_(2))is 1/2,n(Fe^(2+)/H_(2)O_(2))is 1/8,biochemical in-dex B/C increased from 0.075 to 0.533.It greatly improves the biodegradability of wastewater,reduces the difficulty for subse-quent biochemical treatment,and provide a valuable reference for enterprise wastewater treatment.
