Abstract: Aiming at the water characteristics of the high-salinity domestic sewage on an offshore drilling platform,a pilot scale experimental research on the domestic sewage treated by ECO integrative reactor has been accomplished. The effects of current density,hydraulic retention time,pH and temperature on the treatment results of the reactor are investigated. The results show that pH and temperature do not have any influences on the treatment efficacy of ECO integrative reactor. When current density is 10 mA/cm²,hydraulic retention time 60 min,COD concentration of the effluent≤125 mg/L,the requirements of the new discharge standard can be met.

摘要： 针对海上平台高盐生活污水的水质特点，采用ECO（电催化氧化）一体化反应器对其进行了中试试验研究，考察了电流密度、停留时间、pH、温度对反应器处理效果的影响。结果表明：ECO一体化反应器对该类废水的处理效果不受pH、温度的影响，在电流密度为10 mA/cm²，停留时间为60 min的条件下，出水COD≤125 mg/L，达到排放标准的要求。
