湿式过氧化物氧化技术处理高浓度有毒有机废水研究

Research on wet peroxide oxidation treating high concentration noxious organic wastewater

采用湿式过氧化物氧化技术(WPO)处理苯酚丙酮装置某化工厂产生的高浓度有毒有机废水,并在WPO的基础上投加活性炭,加强催化氧化效果。通过单因素实验确定反应温度160℃,反应时间1h,进水pH值为3.0,H2O2投送加量控制在H2O2/COD=0.5,FeSO4按照n[Fe2+]/n[H2O2]=0.1的比例投加,在活性炭催化作用的强化下,COD和苯酚的去除率分别可以达到90%和99%以上。

Wet Peroxide Oxidation （WPO） was applied to treat high concentration noxious organic wastewater discharged by phenol acetone unit. On the basis of WPO, activated carbon was added to enhance the catalytic effect. Experimental results show that under the conditions of reaction temperature was 160℃,pH=3, the feeding of H2O2 is one half of COD. Added a certain amount activated carbon, the removal of COD can reach up to more than 90%. After continuous using of activated carbon, the removal of phenol stabilize at more than 99%.
