摘　　要：采用湿式空气氧化法,对高浓度难生化有机废水进行处理。试验研究在湿式空气氧化法处理有机废水中不同进水浓度对浊度去除率的影响,通过测定水样浊度、浊度去除率的变化,发现,WAO法对不同进水浓度废水的处理效果都是随着反应时间增加而增加,而进水浓度越小,WAO法处理有机废水的效果越好。结果表明,当进水浓度COD=1000 mg/L、反应时间为60 min时,废水浊度去除率可高达86.3%。当进水浓度太大,大于4 000 mg/L时,反应时间也要相应增加,但浊度去除率不高,处理效果也不明显。Refractory organic wastewater with high concentration was treated by the WAO Technology. Influence of wastewater concentration on the turbidity removal rate with the WAO Technology was studied. The results show that the longer the reaction time, the better the treatment effect of WAO Technology for different concentration waste water. And the lower the wastewater concentration, the better the treatment effect of WAO technology for treating organic waste water. When the COD concentration is 1000 mg/L, and the reaction time is 60 min, turbidity removal rate can reach 86.3%. And when COD concentration is more than 4 000 mg/L, the reaction time will increase, and the turbidity removal rate is not high, and the treatment effect is not obvious.
