摘　　要：印染废水中含有大量的重金属离子(铜和铬等)、表面活性剂和有机物,对人体健康产生不利的影响。研究人员提出多种化学和物理过程从废水中去除染料。目前,由于天然聚合物具有低成本和生物相容性等优点,因此,利用天然和改性聚合物去除废水中染料的研究越来越常见。为此,本文对天然聚合物在印染废水处理中的应用进行汇总,同时列举出影响天然聚合物混凝剂活性的因素,从而为相关研究工作者提供借鉴与指导作用。Printing and dyeing wastewater contains a large number of heavy metal ions(such as copper and chromium),surfactants and organics,which adversely effect human health.Researchers have proposed multiple chemical and physical processes to remove dyes from wastewater.Currently,the use of natural and modified polymers to remove dyes in wastewater is increasingly common due to the advantages of low cost and biocompatibility.Therefore,this paper summarizes the application of natural polymers in printing and dyeing wastewater treatment,and also lists the factors affecting the activity of natural polymer coagulants,so as to provide reference and guidance for relevant researchers.
