　　研究采用微米活性炭吸附和 Fenton 氧化组合工艺去除高盐废水中有机物的可行性和效率，同时对各处理单元的反应条件进行优化控制研究。实验结果表明，随着pH降低，活性炭吸附对有机物的吸附效果越好，当活性炭投加量为7 g/L时，TOC去除率为61%，继续增加活性炭投加量不会明显提高TOC去除率。药剂投加方式和反应条件的控制对Fenton氧化的影响很大。在药剂投加总量一致的前提下，分批相比单次投加有机物的去除效率更好，同时维持较高的温度和反应过程中pH可以实现废水中有机物去除效率的最大化。在温度为80℃，维持体系pH为3，过氧化氢投加量为7%(v/v)的条件下(亚铁和过氧化氢摩尔比为0.05)，TOC去除率可以达到90%以上，氧化后废水的TOC小于200 mg/L，达到厂界隔膜电解的进水标准。

The feasibility and effect of removal of organic matters in wastewater containing high NaCl content treatment by using combined process of micro-size activated carbon absorption and Fenton oxidation was investigated in this study. In addition, the optimization control study of operating conditions for each treatment unit was conducted. Resulted indicated that the TOC removal rate enhanced as pH decreased. When dosage of activated carbon was 7 g/L, 61%of TOC could be removed, and TOC removal didn’t increase significantly with further increase of activated carbon dosage. The efficiency of Fenton oxidation on TOC removal was deeply influenced by addition modes of reagents and reactions conditions. Increase of addition times of reagents and temperature could improve removal of organic matters in wastewater. Maximization of TOC removal could be reached by controlling pH as 3. More than 90%of could be reduced when the dosage of H2O2, temperature, reaction pH and molar ratio of ferrous and H2O2 were 7%(v/v), 80℃, 3 and 0.05 respectively.
