摘要
高浓度有机废水具有极大危害,湿式催化氧化法(CWO)是如今常用的方法。本文简单的介绍了湿式催化氧化法的机理及其潜在价值和未来应用。实验结果表明:Fe OOH纳米催化剂的量、H_2O_2浓度、pH值,反应时间都对COD的值有很大影响。我们对新疆独山子炼油厂的汽油碱渣废水进行了研究,确定了由预处理和湿式催化氧化法组成的最佳处理工艺。通过实验得到处理该废水的最佳工艺条件:催化剂的用量为0.05将10000 mg/L的COD值可被降到1000 mg/L。
High-concentration hazardous organic wastewater has huge harm in our life,Wet catalyst oxidation is the common method used in industry.The research speculated the mechanism of wet catalytic oxidation(CWO)its potential value and bright future.Experiment results indicate that the Nano-catalysts FeOOH,H 2O 2 concentration,pH and response time value had a great impact on the COD reduction.We have conducted the research to the Xinjiang Dushanzi refinery gasoline alkali dregs wastewater,and determined the optimum industrial craft of the pretreatment and wet catalyzed co-process.The best process parameters for the treatment of wastewater were as follows:the amount of catalyst was 0.05g,the amount of 30%H 2O 2 was 3 mL,pH=2.0~4.0,and the reaction time was 2 h.The COD concentration was reduced to low than1000 mg/L from as high as 10000 mg/L.
