摘　　要：为了有效处理含有复杂有机污染物的高含盐氯碱废水,采用预氧化微电解工艺预处理该类废水。试验结果表明:在曝气充氧条件下,停留时间为4 h、DO质量浓度保持在1.0 mg/L左右时,COD的去除率在25%左右,多种复杂有机污染物可得到有效的降解,为后续好氧生化处理创造了良好条件。采用本文工艺平均处理成本仅为0.08元/m3。The process of pre-oxidation and micro-electrolysis was used to effectively treat wastewater with a high chloroalkali concentration containing complex organic pollutants. The results showed that the COD removal rate was about 25 % and many complex organic contaminants could biedegrade effectively when the concentration of DO remained at about 1.0 mg/L under aeration oxygen transfer conditions and with the retention time being four hours. Pretreaanent created favorable conditions for further aerobic treatment of the wastewater, and it also reduced the cost to only 0.08 yuan/m3 on
