生化-氧化偶合絮凝法处理含季铵盐高浓度有机工业废水

Treatment of High Strength Quaternary Ammonium Salt-Organic Wastewater with Biochemical-Oxidation and Flocculation Process

采用厌氧 -好氧 -氧化偶合絮凝工艺处理特种有机废水 ,研究了在不同运行参数条件下处理废水的效果。结果表明 ,在进水COD为2 5 0 0～ 3 0 0 0mg/L范围内 ,经厌氧 -二级好氧处理 ,COD总去除率可达 95 % ,再通过氧化偶合絮凝处理 ,出水COD可降至 80mg/L以下 ,COD总去除率可高达 97%以上 ,达到工业废水排放标准。

The effect of applying A/O oxidation and flocculation process to treat special organic wastewater in different operating conditions was studied. The results showed that when the influent COD was 2*!500～3*!000 mg/L, after being treating by A/O/O the total COD removal rate is 95%, and by oxidation and flocculation the effluent COD can be reduced to below 80*!mg/L. The total COD removal rate is up to 97%, meeting the wastewater discharge standard.
