摘要
综述了我国阻燃剂生产使用的现状,概述了阻燃剂大致可分为有机阻燃剂、无机阻燃剂和金属阻燃剂,介绍了阻燃剂对人体以及自然的危害,概括阻燃剂在实际中的应用以及阻燃剂带来的环境污染问题。通过联系大气环境、土壤环境以及实际情况,介绍阻燃剂在自然环境中的迁移,着重分析阻燃剂进入水环境以及阻燃剂在水环境中的转化途径,综述电子、纺织等工业生产、使用阻燃剂是阻燃剂进入水环境的重要途径;降雨使得空气中的阻燃剂溶于雨水,流入市政管网,最终排放河流进入水环境中。由于阻燃剂污染的严重危害,分析阻燃剂废水具有高总磷及高COD等特点,是一种较难处理的废水。根据现在阻燃剂废水处理的实践和研究情况,汇总一些阻燃剂废水处理方法、工艺,主要介绍吸附、萃取工艺、电解法和高级氧化工艺以及化学沉淀等废水处理工艺流程,研究各个工艺的实际处理效果。此外还将各个工艺处理效果进行对比,结合技术经济和运行的实际情况推选出较优工艺为电解、高级氧化结合化学沉淀工艺。最后对我国阻燃剂处理及其污染的控制提出了建议与展望。
This article summarizes the current status of flame retardant production and use in China,and summarizes flame retardants into organic flame retardants,inorganic flame retardants and metal flame retardants.Introduce the harm of flame retardant to human body and nature.Summarize the practical application of flame retardants and the environmental pollution problems caused by flame retardants.By contacting the atmospheric environment,soil environment,and actual conditions,the migration of flame retardants in the natural environment is introduced.The analysis focuses on the flame retardants entering the water environment and the transformation pathways of the flame retardants in the water environment.The use of flame retardants is an important way for flame retardants to enter the water environment;rainfall makes the flame retardants in the air dissolve in rainwater,flows into the municipal pipe network,and finally discharges rivers into the water environment.Due to the serious harm of flame retardant pollution,the analysis of flame retardant wastewater has the characteristics of high total phosphorus and high COD,which is a kind of difficult wastewater to treat.According to the current practice and research of flame retardant wastewater treatment,some flame retardant wastewater treatment methods and processes are summarized.The main introductions are adsorption,extraction processes,electrolytic methods and advanced oxidation processes,chemical precipitation other wastewater treatment processes,and actual processing effect.In addition,the treatment effects of various processes are compared,and the preferred process is selected based on the actual situation of technical economy and operation:electrolysis,advanced oxidation combined with chemical precipitation process.Finally,suggestions and prospects for flame retardant treatment and pollution control in China are put forward.
