次氯酸钠氧化去除气田水中COD研究

REMOVAL OF COD IN GASFIELD WATER BY SODIUM HYPOCHLORITE OXIDATION

简要分析了四川气田水的水质状况 ,提出了电解气田水产生NaClO氧化其中的COD的思路。对温度、停留时间、pH值及NaClO浓度等对气田水中COD氧化的影响进行了实验 ,得出NaClO浓度是影响COD降解的主要因素。根据实验结果 ,对气田水中COD中有机物进行了初步分类 ,并对各类有机物消耗氧化剂的量进行了分析。

According to the properties of gasfield water, it was proposed to oxidize COD by NaClO from electrolyzing gasfield water. Temperature, reaction time, pH and the concentration of NaClO are experimented to their effects on removal of COD in gasfield water. The result shows that the concentration of NaClO is the only affecting factor. According to experiments' result, the organic compounds are classified. It analyzed the consumptive amount of oxidant by each type of organic compound. At last, it gave the suggestion on removal of COD in further research.
