摘要
以白炭黑为载体合成Cu/Al-白炭黑多相芬顿催化剂,构建了多相芬顿催化氧化体系,用以实验室高浓度有机废水处理试验。结果表明:当反应温度25℃,反应体系pH5,催化剂投加量6 g/L,双氧水投加量55 mmol/L,反应120 min时,COD去除率达到52.8%,B/C比由0.06提高至0.36,色度去除率80%。与传统芬顿法相比,多相芬顿体系对高浓度有机废水COD去除率提高12.8%,B/C提升12.5%。催化体系经5次重复后依然保持较为理想的处理效果,反应过程金属离子溶出1.86%,出水无需进行金属离子沉淀处理,可直接进行生化处理。
A Cu/Al-white carbon black multiphase Fenton catalyst was synthesized by using silica as a carrier to construct a multiphase Fenton catalytic oxidation system for laboratory high concentration organic wastewater treatment experiments.The design aims to improve the traditional Fenton method.The test results show that when the reaction temperature is 25°C,the pH value of the reaction system is 5,the dosage of the catalyst is 6 g/L,the dosage of hydrogen peroxide is 55 mmol/L,and the reaction time is 120 min,the COD removal efficiency is 52.8%,the B/C increases from 0.06 to 0.36,and the color removal rate is 80%.Compared with the traditional Fenton method,the multiphase Fenton system increases the COD removal efficiency of organic wastewater by 12.8%and the B/C by 12.5%.The catalytic system still maintains an ideal treatment effect after five repetitions.Metal ion dissolution is 1.86%during the reaction process,and the effluent does not need to be subjected to metal ion precipitation treatment,and can be directly biochemically treated.
