摘要
硝基苯类化合物的高毒性、难降解性及其在环境中的积累性,使得硝基苯污染治理越来越受到科研工作者的关注。近几年国内外硝基苯废水治理的研究主要包括物化法、生物法两大类。深入探讨每种技术的基本原理和存在的问题,对硝基苯类废水的处理难点和关键技术以及今后的研究方向进行了分析探讨,发现目前尚未出现具有显著经济和环境优势的技术,同时还指出硝基苯废水处理技术近期的进展可能取决于将现有处理技术综合应用。
Due to its high toxicity and refractory,nitrobenzene compounds has been accumulated chronically and does serious harm to human beings.Pollution problems involved are being seriously concerned.In this paper,latest technology and methods for treating wastewater containing nitrobezenes were reviewed,such as physicochemical process and biochemical technologies etc.The mechanisms of each technology,some latest research results and potential development about controlling nitrobenzenes pollution were discussed in detail.And it is pointed out that until now there are not processes characterized by remarkable economic and environmental benefits,and the development of the treatment technologies for nitrobenzene wastewater will be mainly depended on the integrated application of the existing processes.
