高铁酸钾氧化处理垃圾渗滤液实验研究

高铁酸钾不仅可以消毒,而且对环境友好,是一种集氧化、吸附、絮凝、助凝、杀菌、杀虫、除臭为一体的新型高效多功能绿色水处理剂。本文采用高铁酸钾处理垃圾填埋场渗滤液,改变高铁酸钾的投入量、渗滤液pH值和处理的反应时间来考查处理效果,结果表明,COD和氨氮的去除效果均有显著的影响。当pH值为8,高铁酸钾投入量为6 g,反应时间为60 min时对COD的去除效果最佳。当pH值为8,高铁酸钾投入量为6 g,反应时间为40 min时氨氮的去除效果最佳。

Experimental Study on Landfill Leachate Treatment with Potassium Ferrate Oxidation Method

This study adopts potassium ferrate to treat landfill leachate by changing the potassium ferrate dosage,leachate pH,reaction time and processing methods to examine the treatment effect.Results showed that the removal rate of COD and ammonia nitrogen are major influencing parameters.When the pH value is 8,potassium ferrate dosage 6g,the reaction time was 60 min to achieve optimal COD removal rate.With pH value of 8 and potassium ferrate dosage of 6g,the optimal ammonia removal rate will be achieved with reaction time of 40 min.
