芬顿+改良活性炭深度处理垃圾渗滤液的应用

主要研究了芬顿+改良活性炭深度处理垃圾渗滤液在实际工程中的应用。考察了初始运行的处理效果,CODCr、SS、色度均能达标,UV254(反映腐殖酸类物质的量)的去除效果表较明显。对吸附剂的实际吸附能力进行了考察,一级吸附在运行110天时才出现吸附效率明显降低,二级吸附在一级吸附能力下降时可以保证较高的去除率(70%以上)。该工艺深度处理中晚期垃圾渗滤液药剂费和活性炭更换费之和为21.27元/吨水,可以满足渗滤液处理的经济性要求。

The Application of Advanced Landfill Leachate Treatment of Fenton Oxidizing-Modified Activated Carbon Adsorption

The practical engineering application of Fenton oxidizing and modified activated carbon process adsorption in depth disposal of landfill leachate was studied.The initial operation was inspected , which showed that the effluent quality index such as CODCr, SS and chroma could reach the discharge standard, the removal effect of a extra index of UV254 , which reflected the amount of humic acid substances was remarkable.The adsorption capacity of the adsorbent was investigated, and the first-stage adsorption performed a great efficiency until 110 running days.The second-stage adsorption could guarantee a high removal rate （ higher than 70%） when the first -stage performed worse than initial.The advanced treatment costed 21.27 yuan per ton for aged leachate to acquire the agents and replace the used activated carbon.It showed that this process could meet requirement of landfill leachate advanced treatment with low cost.
