摘要:

采用氯化十二烷基二甲基苄基铵改性后的改性黏土吸附剂Y处理不同类型的染料工艺废水。通过实验研究不同条件下,不同类型废水COD和色度的去除率以及吸附规律,探讨活性黏土和改性黏土吸附剂Y所带官能团与其降低废水中COD和色度的规律。

关键词: 黏土, 染料工艺废水, 吸附

Abstract:

Different types of wastewater from dyestuff technology are treated by using modified clay adsorbent Y, which is modified from activated clay with cationic functional group (dodecyl dimethyl benzyl ammonium chloride). Under different conditions, the COD removal rate, chromaticity removal rate and adsorption regularity have been studied.The activated clay, modified clay adsorbent Y with its functional group and the regularity of lowering COD and chromaticity are discussed.

Key words: clay, wastewater from dyestuff technology, adsorption
