以无泡曝气膜组件为氢源和氧源的释放装置，分别建立厌氧还原修复区和好氧氧化分解区，并考察了氢气和氧气曝气压力对水相氧化还原电位的影响及曝气过程对厌氧还原脱氯反应、好氧氧化分解反应的影响。结果表明：厌氧还原脱氯区的氧化还原电位-水相停留时间曲线均呈现出上开口抛物线特征；好氧氧化分解区的氧化还原电位-水相停留时间曲线均呈现出下开口抛物线特征；两个修复区的最佳停留时间比例为4∶1。

Using the bubbleless-aeration membrane module as the releasing device of hydrogen and oxygen sources, the anaerobic reductive remediation area and the aerobic oxidative decomposition remediation area have been estab-lished. The effects of aeration pressure of hydrogen and oxygen on oxidation reduction potential (ORP) aqueous and the effect of aeration process on anaerobic reduction dechloridation reaction and aerobic oxidation decomposition reaction are investigation,respectively. The results show that the ORP-aqueous retention time curve in anaerobic reductive dechlorination remediation area presents an up-opening parabolic feature of growth ,while the ORP aque-ous retention time curve in aerobic oxidative decomposition remediation area presents a feature of down-opening parabola of growth. The optimal proportion of the retention time of the two remediation areas is 4∶1.
