新型铁碳微电解填料处理含苯污染地下水的实验

将土壤、铁屑、活性炭以及添加剂按一定比例混合、造粒，再经过加热焙烧后制备成新型铁碳微电解规整化填料，以模拟含苯类污染质的污染地下水为研究对象，考察了粘土、铁碳比、填料粒径、粘土比例、添加剂及焙烧温度等因素对微电解过程处理效果的影响。结果表明：粘土经焙烧后对苯的吸附作用很小；在铁碳质量比为6∶1，粘土的质量分数为25%，焙烧温度为300 ℃的制备条件下，填料对苯的处理效果最佳。用该填料处理含苯系物污染地下水，连续稳定运行后，处理率可以达到80%以上。

Treatment of Benzene in Simulated Polluted Groundwater by New Iron-Carbon Micro-Electrolysis Packing

The iron-carbon micro-electrolysis packing was made by the method of calcination. The influences of clay, Fe/C mass ratio, clay proportion, packing diameter, additives and calcination temperature on the removal rate of simulated benzene groundwater were investigated. The results showed that the adsorption effect of clay after calcination was little; The optimum conditions of preparation for treating were Fe/C mass ratio 6∶1, clay proportion 25%, calcination temperature 300℃. The packing was used to treat BTEX groundwater, and the removal rate was over 80% after running steadily.
