摘要
通过试验初步研究活性炭直接吸附去除印染工业废水色度中吸附剂投加量、吸附时间等对色度去除率的影响。通过混凝沉淀法与活性炭吸附法结合、搅拌电解法与活性炭吸附法结合、脱色氧化法与活性炭吸附法结合等试验初步探讨了活性炭吸附与其它处理方法结合去除印染工业废水色度的可行性。同时,讨论了以上几种处理方法对水样中CODCr的去除、水样pH值变化等的影响。
This paper reviews the influence of activated carbon quantity, adsorption-time, etc. on decolorization efficiency of dyeing and printing wastewater. The feasibility of combining other processes with adsorption is discussed, including coagulation, electrolysis and oxidization, The change of CODCr and pH are also discussed as well,
