摘要
季铵盐类化合物是一种重要的化工产品,广泛应用于日常生活和工业领域,使其不可避免地进入环境水体中。由于QACs的强吸附特性和生物毒性,使得富集于污泥/沉积物中的浓度可达几百mg/kg。因此,有效去除水体中的QACs具有重要的环保意义。本文介绍了QACs的类型、废水来源、生物毒性及废水处理方法的最新研究进展。针对现有技术的局限,探讨了该废水处理领域的未来研究重点和方向。
Quaternary ammonium compounds(QACs)used as important chemical products that are widely applied in household and industrial fields,and are inevitably released into the environmental waters.The concentrations of QACs in sludge/sediment can be examined highly at several hundreds of mg/kg due to their strong adsorption and biological toxicity.Therefore,it is of great environmental significance to effectively remove QACs from wastewater.This paper reviewed the latest development of the types,wastewater sources,biological toxicities and treatment technologies of QACs.The key research aspects and directions of wastewater treatment in this field were discussed based on the analysis of drawbacks of current technologies.
