摘要
随着溴代阻燃剂的全球禁用,有机磷阻燃剂(OPFRs)以低烟、无毒、低卤、无卤等优点逐渐取代溴代阻燃剂。但由于其热稳定性不佳,挥发性大且常以非化学键的方式添加在产品中,因此极易扩散到周围环境中。目前,在水体、沉积物、生物体等中已检测出OPFRs的存在。人工湿地是由湿地基质、微生物、植物等建成模拟天然湿地的一种处理污水技术,由于其投资少、运行成本低等明显优势,目前在污水处理中已然成为主力军。本文运用文献法对人工湿地处理OPFRs的应用进行了阐述,总结了复合垂直流人工湿地对OPFRs的处理效果,为去除水体中的OPFRs带来一些帮助。
With the global disability of the broma flame retardant, organic phosphorus flame retardants (OPFRS) gradually replaced bromine flame retardants with the advantages of low smoke, non-toxic, low halogen, and halogen-free. However, due to its poor thermal stability, large volatility, and often adding non-chemical bonds to the product, it is easy to spread in the surrounding environment. At present, the existence of OPFRS has been detected in water bodies, sediments, and organisms. Artificial wetlands are a kind of sewage technology that simulates natural wetlands from wetland matrix, microorganisms, plants, etc., and has become the main force in sewage treatment due to its obvious advantages such as investment and low operating costs. This article uses the literature method to explain the application of OPFRS for artificial wetlands, summarizes the processing effect of composite vertical flow artificial wetland on OPFRS, and helps some help to remove OPFRS in the water body.
