氯酚类化合物的污染现状及去除方法研究进展

Progress in Pollution and Removal of Chlorophenol Compounds

氯酚类化合物广泛用于造纸、印刷、纺织印染、皮革、涂料、制药等行业产品的原料及防腐消毒,成为环境中典型的有机卤代污染物,具有致畸、致癌、致突变的"三致"作用和环境持久性。文中综述了氯酚类化学污染物的来源及其在水体、底泥沉积物和土壤以及生物体内的污染水平,着重阐述了生物法、物理化学法、化学还原以及化学氧化法等对氯酚类污染物的降解和去除,并进行了总结和展望,指出开发绿色环保、反应高效、价格低廉的单元技术或联合工艺实现氯酚类污染物的无害化处理是未来的发展方向。

Chlorophenol compounds (CPs), typical halogenated organic pollutants with the characteristics of teratoeenesis, carcinogenesis,mutagenesis and environmental persistence, are widely used for raw materials and antiseptic disinfection in papermaking, printing,textile printing and dyeing, leather, paint, pharmaceutical, and other industries. The source, pollution level in water, sediment and soil,and biological body, and degradation processes of CPs are overviewed, focusing on the degradation and removal techniques, such as biotechnology, physical and chemical method, chemical reduction, and chemical oxidation process. Ultimately, a summary and expectation for degradation and removal processes of CPs are listed, which indicates the exploration of unit technology or joint processes with green initiative, high efficiency, and lower price to achieve free-pollution disposal of CPs pollutants is the development direction for the future.
