地下水-土系统中苯并三唑去除方法研究

Removal Methods of Benzotriazole from Groundwater-Soil System

含苯并三唑的地下水很难用常规的水污染处理方法去除,因此迫切需要探讨它在地下水-土系统中有效的去除方法。详细介绍了吸附法、光激发氧化法和生物法,并且针对这些方法应用到地下水中的可行性进行了分析。结果表明,吸附法受到环境因素的限制,并会发生缓慢的解析过程,需进一步探索和完善;光激发氧化法去除效果较好但仍处于探索阶段,需改善耗费较多人力、物力、财力的缺点。目前的生物法很难对苯并三唑进行降解,尚需要进一步的研究。

It was difficult to remove benzotriazole （BTA） in groundwater with conventional water treatment methods. Therefore, there is an urgent need to assess the effective removal methods in groundwater-soil system. The adsorption methods, UV-O3 methods and biological methods were introduced in this article. The feasibility of applying these methods in groundwater was discussed. The results indicated that the adsorption method is limited by environmental factors and needs to be improved for real application. The removal effect of BTA by UV-O3 method is good, however, its application is still in the preliminary stage. The UV-O3 technology needs more manpower, material and financial resources. More works need to be carried out in the biological removal of BTA in groundwater-soil system.
