【摘要】 采用絮凝、毒性及生化试验，确定了废水处理最佳工艺流程，研究了浓度、停留时间对ＣＯＤ去除率的影响．结果表明，该有机废水采用絮凝净化效果不大，且对生化处理具有一定的抑制作用，当系统进水ＣＯＤ为 ３０００ｍｇ／Ｌ，流量为１Ｌ／ｈ时；经过厌氧、两级好氧处理后，出水中ＣＯＤ可降至１５０ｍｇ／Ｌ以下，总去除率可达９５％以上，达到了工业废水排放标准．更多还原

【Abstract】 The best process of treating wastewater was defined by flocculation. toxic and biochemical experiment. The concentration of wastewater and stay time affecting the removal efficiency of COD were studied. Experiment results showed; treating organic wastewater by flocculation was not very effective and organic wastewater inhibited biochemical treatment, when the influent COD was 3000mg/g and flow was 1L/h, after being treated by A/O/O the effluent COD can be reduced to less then 150mg/L with the total removal efficiency more then 95% to meet the wastewater discharge standard.更多还原
