摘　　要：间羟基二乙基苯胺是一种染料中间体,其生产废水CODCr高,成分复杂。应用曝气吹脱 电解法对其高盐废水预处理工艺进行了可行性的研究,建立了曝气吹脱 电解法预处理方案。曝气吹脱与电解法的CODCr去除率分别可达20%与80%,提高了可生化性,便于后接生化处理。经实验优选最佳工艺参数为:曝气吹脱pH值4 0,曝气吹脱时间90min;电解进水pH值7 0左右,电解外加电压7V,电解停留时间120min,电极板间距3cm。m -Hydroxy diethyl aniline is one kind of dyeing intermediates which have high concentration of COD _(Cr) and salinity and various components in their produced wastewater. A wastewater pretreatment method was applied to study on the feasibility and effect of the treatment. A treatment process that aeration followed by electrolysis was founded. The results showed that the removal efficiency approached to 20% and 82% respectively and the method can improve biological treatment. The optimum process condition was that aeration pH value 4.0 or so, aeration time 90 minutes;voltage value 7 V, electrolysis remained time 120 min, electrode space 3cm when electrolyzing.
