[摘要]  以某石化企业的二级处理的出水为研究对象,采用三元微电解—Fenton 氧化工艺对其进行深度处理,使其达到循环冷却水水质标准。通过正交试验考察了微电解最佳操作条件,单因素试验考察了Fenton 氧化最优条件。微电解—Fenton 氧化组合工艺深度处理石化废水的试验结果表明,该工艺可使COD、SS 及浊度得到较好的去除,出水水质达到了循环冷却水的用水标准。

Treatment of reused petrochemical wastewater by ternary microelectrolysis-Fenton oxidation process
Yang Ruihong1,Liu Yakai2
Abstract:The secondary-treated effluent in a petrochemical enterprise has been studied,and the ternary bined with Fenton oxidation process is used for the advanced treatment of it,so as to reach the circulating cooling water quality standard. The best micro-electrolysis operating conditions are investigated by orthogonal tests. The optimal conditions of Fenton’s reagent oxidation are investigated by single-factor tests. Applying bined microelectrolysis-Fenton reagent oxidation process to the advanced treatment of petrochemical wastewater through flow experiments can make the removing efficiency of COD,SS and turbidity get better,reaching the circulating cooling water quality standard. Key words: ternary micro-electrolysis;Fenton oxidation;reused treatment;petrochemical wastewater
废水回用是节水减排的重要途径和主要内容,随着水资源的日趋紧张及水费的持续上调,废水回用不仅具有重要的环境效益和社会效益,其经济效益也必将进一步地体现出来。废水处理与回用的潜力巨大,寻求高效率、低成本的废水深度处理工艺是目前废水资源合理利用研究的热点问题。目前微电解技术在污水处理中的应用研究越来越广泛和成熟〔1-2〕。Fenton 氧化法主要是利用
