摘要
研究了臭氧催化氧化技术在处理MMA高有机物及高氰化物废水中的应用。通过实验优化反应条件,分析了臭氧浓度、催化剂投加量和反应时间对废水中有机物和氰化物的降解效果。结果表明,臭氧催化氧化技术能够显著提高COD和TOC的去除率,在120 min的反应时间内,COD去除率达到85%,TOC去除率为82%。通过负载MnO_(2)的催化剂,不仅改善了催化剂的孔结构,还有效增强了催化反应的效率。在氰化物降解方面,随着臭氧浓度的增加,氰化物的降解率提高,臭氧浓质量度达到70 mg/L时,氰化物降解率为85%。与传统Fenton法对比,臭氧催化氧化技术在电耗、催化剂消耗及污泥处置费用方面均具有显著优势,表明其在废水处理中的经济性和可行性。研究结果为臭氧催化氧化技术在高浓度有机废水和氰化物废水处理中的应用提供了有力支持。
The application of ozone catalytic oxidation technology in the treatment of MMA high organic matter and high cyanide wastewater was studied.The degradation effects of organic matter and cyanide in wastewater were analyzed by optimizing reaction conditions through experiments,including ozone concentration,catalyst dosage,and reaction time.The results showed that ozone catalytic oxidation technology can significantly improve the removal rates of COD and TOC.Within a reaction time of 120 minutes,the COD removal rate reached 85%and the TOC removal rate was 82%.By loading MnO_(2)catalyst,not only the pore structure of the catalyst is improved,but also the efficiency of the catalytic reaction is effectively enhanced.In terms of cyanide degradation,as the concentration of ozone increases,the degradation rate of cyanide increases.When the concentration of ozone reaches 70 mg/L,the degradation rate of cyanide is 85%.Compared with the traditional Fenton method,ozone catalytic oxidation technology has significant advantages in electricity consumption,catalyst consumption,and sludge disposal costs,indicating its economic and feasibility in wastewater treatment.The research results provide strong support for the application of ozone catalytic oxidation technology in the treatment of high concentration organic wastewater and cyanide wastewater.
