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

摘要: 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2500～3000mg/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。

Abstract: 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.
