摘要
铝土矿经改性后,针对高质量浓度有机废水的处理进行了试验研究,确定了最佳处理试验条件。试验结果表明,在pH值为10、改性铝土矿投加量分别为6g/L和10g/L、搅拌速度为60r/min、搅拌时间分别为30min和40min的条件下,初始质量浓度为6 250mg/L的有机废水去除率为73.5%,初始质量浓度为54 600mg/L的有机废水去除率为64.2%。
Treatment of high concentration organic wastewater was carried out with modified bauxite and the optimum experimental conditions were confirmed. The results showed that the optimum conditions were ： pH = 10, the velocity of stirring was 60r/min , the amount of modified bauxite were 6.0g/L and 10g/L and the stir time were 30min and 40min respectively for two kinds of high concentration organic wastewater. The removal efficiency of high concentration organic wastewater with the original concentration of 6 250mg/L and 54 600mg/L were 73.5% and 64.2% respectively.
