摘要
采用铁碳微电解法预处理制药废水,研究影响微电解预处理废水的各种因素。实验探讨了铁碳比、pH值及反应时间对废水COD(化学需氧量)去除率的影响,以确定最佳工艺条件。研究结果表明:微电解法处理制药废水时,当原水的pH值为4,Fe/C比为2:1,反应时间80min,COD去除率为68.0%。
An experiment of micro-electrolysis pretreatment of pharmaceutical wastewater has been carried out, and the factors that affected the results were also studied. We investigated the conditions which affected the COD removal such as Fe/C ratio, pH and reaction time to determine the optimum conditions. The results show that, for the treatment of micro-electrolysis process, more than 68.0% COD of the pharmaceutical wastewater is removed under the best condition that pH is 4, mass ratio of iron-carbon is 2：1, reaction time is 80min.
