钠型累托石处理印染废水

文章的正交实验研究表明:(1)用改性累托石处理印染废水中的浊度及COD,在废水pH为5,改性累托石用量为110 mg/L,搅拌时间为20 min,搅拌速率为50 r/min时,最优化条件下,经验证实验,COD去除率可达50%。浊度去除率可达96,71%。(2)影响浊度去除率的因素主次顺序是:改性累托石用量pH搅拌速率搅拌时间。影响COD去除率的因素主次顺序是:改性累托石用量pH搅拌时间搅拌速率。

Treatment of Dyeing Wastewater with Na-Rectorite

In the paper,orthogonal experimental method of coagulating sedimentation rectorite modified to deal with the study of printing and dyeing wastewater.The experiments showed that:(1)satisfactory results of deep treatment could be obtained at pH=5 with modified rectorite dosage at 110 mg/L,stirring time at 20 min and stirring rate at 50 r/min.Turbidity removal96.71 % and COD removal 50.00 %.Factors that affect the turbidity removal efficiency of primary and secondary sequence was: the amount of Modified Rector...
