摘要：

针对橡胶促进剂生产废水有机毒物含量高、成分复杂等特点,采用颗粒活性炭对其进行低浓度吸附研究。结果表明,pH为4.0~5.0,进水COD为500mg/L,100mL废水活性炭用量为5.0g,废水COD平均去除率达68%。经动力学分析,均可用Freundlich等温式和Langmuir等温式较好拟合。

Abstract:

Aiming at the high content of poisonous organisms and complicated components of the rubberaccelerant wastewater, the particle active carbon has been adopted to study on the lowcon centration adsorption.Theresults showthat theaverage COD removal ratereaches 68%when the pHis 4-5, theinfluent wastewaterconcentration is about 500mg/Land the active carbon consumption amount is50g/L. Meanwhile, thedynamicanalysis of the results is conducted and it is found that the Freundlich isothermal equation and Langmuirisothermal equationcanfit well.

Key words: adsorption, rubber accelerant wastewater
