摘要
为了探究铁碳微电解工艺在含盐环境下对水中污染物的去除效率和稳定性,以硝基苯作为处理对象,以氯化钠为盐分来源,构建模拟废水的连续处理装置,通过单因素试验获得反应最佳条件.研究结果表明,铁碳微电解处理硝基苯废水的最佳条件为:废水初始pH值为3,水力停留时间为2h,曝气量为1 L/min;此条件下氯化钠对铁碳微电解降解硝基苯具有明显的强化作用,在氯化钠质量分数为0.5％～1.5％时,硝基苯去除率可提高 20％～30％.
Abstract
In order to explore the removal efficiency and stability of pollutants in water using iron carbon micro-electrolysis technology in saline environment,taking nitrobenzene as the treatment object and using sodium chloride as salt source to construct a continuous treatment device for simulated wastewater,then,the optimal reaction condition was obtained through single factor experiments.The results showed that,the optimal condition for iron carbon micro-electrolysis technology treating nitrobenzene wastewater was as follows:the initial pH value of the wastewater was 3,the HRT was 2 h,the aeration rate was 1 L/min.Under the above condition,NaCl had a significant strengthening effect on the degradation of nitrobenzene by iron carbon micro-electrolysis,when the mass fraction of sodium chloride was 0.5％-1.5％,the removal rate of nitrobenzene could be increased by 20％-30％.
