Description
技术领域
本发明涉及水处理领域,具体涉及一种去除水体中溴代阻燃剂的方法。
背景技术
溴代阻燃剂(BFRs)是一类具有优良阻燃性能的有机物,广泛用于塑料制品、纺织品、电子产品和建筑材料中。其中四溴双酚A(TBBPA)是目前中国产量最大、用量最高的溴代阻燃剂。在TBBPA的生产、转运、使用和废弃物处置过程中,大量的TBBPA及其它酚类污染物如双酚A(BPA)、三溴苯酚(TBP)等从材料中释放,进入食物链和生态环境,对自然环境以及人体健康构成威胁。
目前针对溴代阻燃剂的去除方法主要有生物法、物理法以及高级氧化法等。生物法运行成本低廉、适用范围广,但是对溴代阻燃剂去除效果有限。物理法主要有吸附法和膜过滤法,其中吸附法利用吸附剂丰富的微孔结构和巨大的比表面积去除水中污染物,但是在吸附过程中目标污染物只是被转移并没有被降解,因此存在二次污染的风险。膜处理技术依靠膜的孔径对溴代阻燃剂进行截留,然而膜污染是限制膜技术大规模应用主要因素。
近年来,高级氧化技术(AOPs)越来越广泛地应用于印染、制药等工业废水的处理中。高级氧化法通过氧化剂在一定条件下产生的具有强氧化能力的羟基自由基(·OH)或硫酸自由基(SO4-·),将有机污染物氧化分解成小分子物质,主要技术有臭氧氧化、紫外光照射、过硫酸盐高级氧化等,其中关于氯自由基研究相对较少,而氯氧化剂在水处理中应用更加广泛。因此,开展和氯氧化有关的AOPs在水处理中,特别是对高毒性、难降解的污染物处理方面,具有非常好的发展前景。
紫外线(UV)是一种波长范围100-400nm的不可见光,能产生有效的光化学反应,被广泛应用于水处理技术中。在目前的应用中UV常和各种氧化剂(O3、H2O2、PS)或光催化材料(TiO2)等联用,通过UV的光照作用,促进各类自由基的产生,提高对污染物的去除效果。紫外/氯高级氧化被广泛应用于水处理领域,其原理为:水中的氯在紫外光的辐照下发生光解反应,产生强氧化性的氯自由基(Cl·)及羟基自由基(OH·),各自由基可以通过脱氢、加成、电子转移等方式高效快速降解水中有机污染物。随着半导体技术的迅猛发展,紫外发光二极管(UV-LED)应运而生,并成为紫外辐射新光源。与传统汞灯紫外相比,UV-LED具有能耗低、效率高、体积小、无毒无害、环境友好、使用寿命长等优点,被认为是传统紫外汞灯的良好替代品。
UV-LED作为新型紫外光源拥有巨大的应用前景,而国内对UV-LED的研究工作起步较晚,当前对其的研究很少,研究结果局限在365nm-400nm近紫外范围内。因此探究UV-LED在水处理领域的应用具有极大的研究意义。
中国专利CN104961188A公开了一种有效去除水中四溴双酚A的方法,包括如下处理步骤,(1)获得具有四溴双酚A分子印迹功能的二氧化钛多孔微球;(2)加入FeSO4·7H2O晶体和NaBH4溶液,得到具有四溴双酚A分子印迹功能的二氧化钛多孔微球负载的纳米铁粉末;(3)加入AgNO3溶液得到负载有纳米铁-银双金属纳米颗粒的印迹二氧化钛多孔微球;(4)将制得的负载有纳米铁-银双金属纳米颗粒的印迹二氧化钛多孔微球加入到含有四溴双酚A的废水中;(5)用外部磁铁将吸附有四溴双酚A的复合多孔微球与净化后的水分离,分离后的负载有纳米铁-银双金属纳米颗粒的印迹二氧化钛多孔微球转移至安装有光源的光催化反应池内进行汞灯紫外进行照射处理,该方法步骤复杂,成本较高。
中国专利CN205076933U公开了一种生活污水深度处理装置,通过气体压缩机、汞灯紫外和含氯氧化剂入口的设置,进一步降低了处理后污水中的有机物,大大降低了处理后污水的COD值和BOD5值,然而并不是针对水体中溴代阻燃剂。
