摘　　要：硝基苯类化合物广泛存在于火炸药、石化、染料等行业,在其生产过程中产生大量硝基苯类废水,因其结构稳定、毒性大、可生化性差等特点备受广大科技工作者关注。传统废水处理方法存在传质受限、处理效率低等问题,利用超重力技术强化处理硝基苯类废水成为一种新的颇具潜力的方法。本文综述了超重力强化物理法、还原法、臭氧高级氧化法等处理硝基苯类废水方法研究进展,包括强化传质过程、材料制备、催化降解等方面,并对超重力强化处理硝基苯类废水放大过程中应关注的关键问题以及今后对优化结构、延长液体停留时间的研究方向进行了阐述和展望。Nitrobenzene compounds widely exist in the explosives,petrochemical,dye and other industries,and a large amount of nitrobenzene wastewater are produced in the production process,which is of great concern to scientists because of its stable structure,high toxicity and poor biodegradability.Traditional wastewater treatment methods have limited mass transfer and low treatment efficiency,and the enhanced treatment of nitrobenzene wastewater using high gravity technology has become a new and promising method.In this paper,the research progress in the treatment of nitrobenzene wastewater by high gravity enhanced physical method,reduction method and advanced ozone oxidation method is reviewed,including enhancing mass transfer process,material preparation,catalytic degradation and so on,and the key issues of scale‑up process and future development for improving structure and extending the liquid residence time for high gravity enhanced treatment of nitrobenzene wastewater that should be concerned are discussed and prospected.
