摘　　要：利用铁、炭间接电偶腐蚀原理,设计了铁炭原电池反应器。围绕该反应器对高盐废水总有机碳(TOC)的净化性能、操作模式(间歇、连续与半连续)以及影响因素等方面进行了研究。结果表明:铁炭原电池反应器的铁室具有良好的还原性,炭室具有良好的氧化性,高盐废水有机物的去除效果显著;反应器的半连续操作模式对高盐废水有机物去除效果最佳;半连续模式下的较佳操作条件为:固液比为15%,pH=1.7,流量为1.0 mL·min^(-1)。在较佳操作条件下,铁室对废水TOC的去除率可达98.7%以上,而炭室对废水TOC的去除率可达99.1%以上。An iron-carbon primary battery reactor has been designed in this study using the principle of indirect galvanic corrosion of iron and carbon.The purification performance,operation mode(batch mode,continuous mode and semi continuous mode)and influencing factors of the reactor removing total organic carbon(TOC)from high salinity wastewater were experimentally explored.The results show that for the iron-carbon primary battery reactor,its iron chamber had a good reducibility,its carbon chamber had a good oxidability,and the removal effect of organic matter in high salinity wastewater was significant;The semi continuous operation mode of the reactor had the best removal effect on organic matter in high salinity wastewater;Under the semi continuous operation mode,the optimal operating conditions were following:the solid-liquid ratio of 15%,pH=1.7,and the flow rate of 1.0 mL·min^(-1).Under optimal operating conditions,TOC removal rate from wastewater by the iron chamber could reach over 98.7%,while TOC removal rate from wastewater by the carbon chamber could reach over 99.1%.
