摘　　要：对高铁酸钾处理垃圾填埋场渗滤液废水方法进行研究和探讨,实验结果表明,高铁酸钾处理效果受K_(2)Fe O_(4)掺加量、处理反应时间、初始p H影响。渗滤液废水中的UV_(254)、COD_(cr)去除率随着K_(2)Fe O_(4)掺加量的增加而升高,高铁酸钾掺加量为3.0 g/L时,两项指标的去除率最高且不再上升;0~10 min内,UV_(254)去除率升高迅速,10 min后反应基本完成;p H=5时,UV_(254)、COD_(cr)两项指标去除率最高,分别可达到48.9%、50.8%。该处理方式反应后p H都会有一定程度的升高,终止条件为弱碱性时,可大大高氢氧化铁的絮凝效果。The treatment of landfill leachate wastewater by potassium ferrate was studied and discussed.The experimental results showed that the treatment effect of potassium ferrate was affected by the dosage of potassium ferrate,reaction time and pH.The removal rates of UV_(254) and CODcr in leachate wastewater increased with the increase of potassium ferrate.When the addition of potassium ferrate was 3.0 g/L,the removal rates of the two indexes were the highest and did not rise.Within 0~10 min,the outgoing rate of UV_(254) increased rapidly,and the reaction was basically complete after 10 min.When pH=5,the removal rates of UV_(254) and CODcr can reach 48.9%and 50.8%respectively.After the reaction,the pH will be increased to a certain extent,and when the termination condition is weak alkaline,the flocculation effect of high iron hydroxide can be greatly enhanced.
