摘　　要：针对填埋场渗滤液COD和氨氮高浓度、难去除问题,通过水化剂处理试验研究,考察无机盐种类、投加量对处理效果的影响,以及活性炭、硅藻土和离子吸附树脂预处理的影响。试验结果表明:矿化生物床尾水经水化剂处理后,COD、氨氮能够有效去除,去除率分别为25.12%、95.47%;无机试剂的种类及投加量对水化剂处理效果有一定抑制作用;活性炭、硅藻土及阴离子树脂预处理后,水化剂的去除效果明显增加,活性碳、硅藻土、离子吸附树脂对COD的去除率分别为53.37%、48.85%和54.72%,对氨氮的去除率分别为89.22%、96.72%和88.13%,对TOC的去除率分别为87.32%、72.36%和75.70%,为渗滤液出水质满足《生活垃圾填埋场控制标准》(GB16889-2008)的最新排放标准奠定了基础。In order to solve the problem of COD and ammonia nitrogen in landfill leachate with high concentration and difficulty in removal,the treatment effects of types and dosage of inorganic salt,as well as the pretreatment effects of activated carbon,diatomite and ion adsorption resin were investigated through the experimental study of hydration agent treatment.The test results showed that COD and NH4-N of tail water of mineralized bioreactor could be effectively removed by hydrating agent treatment,and the removal rates were 25.12%and 95.47%respectively.The type and dosage of inorganic reagent showed a certain inhibitory effect on the treatment effect of hydrating agent.The removal effect of hydrating agent was significantly increased after pretreatment with activated carbon,diatomaceous earth and anion resin,the removal rates of COD by activated carbon,diatomaceous earth and ion-adsorbing resin were 53.37%,48.85%and 54.72%,respectively.The removal rates of NH4^+-N were 89.22%,96.72%and 88.13%,respectively.And the removal rates of TOC removal were 87.32%,72.36%and 75.70%,respectively.It lay a foundation for the leachate effluent quality to meet the latest emission standard of Standards for Landfill Control(GB 16889-2008).
