摘要
氯代硝基苯属典型的异生物合成物质,是重要的基础化工原料,其化学性质稳定,生物降解性差,且具有三致效应。该类废水的处理是目前我国水环境治理和水安全保障的重大难题。综述了目前含氯代硝基苯工业废水的处理技术,包括物理吸附萃取、化学氧化还原、电化学和生物处理工艺以及新型耦合处理工艺等,比较其优缺点并重点阐述了新型耦合处理工艺,发现其研究热点逐步从传统单一处理技术过渡至耦合处理工艺,专性高效降解菌分离筛选、反应器构型改进和新型廉价材料开发以及物化-生物耦合工艺研发将成为未来发展的主要方向。
Chloronitrobenzenes （CINBs）, as typical xenobiotics and important chemical intermediates, are becoming the major problem for the water environment treatment and drinking water security in China. CINBs have mutagenicity and genotoxicity, and threaten ecological security and human health due to their refractory and biological accumulation. In this paper, conventional treatment processes of chloronitrobenzenes in industrial wastewater including adsorption, extraction, redoxprocess, electrochemical techniques and biological treatment technology were summarized, and novel coupled systems developed for enhanced chloronitrobenzenes degradation were elaborated in detail. According to the literatures, research on the treatment processes has been focused on the coupled systems. Screening the high-efficiency degradation strains, improving the exsiting processes and materials and developing the novel coupled systems are becoming the maj or direction of researches on treatment technology ofwastewater containing chloronitrobenzenes.
