含硝基芳香族化合物废水处理技术研究进展

为探讨含硝基芳香族化合物废水高效低耗的处理技术,综述了该类废水处理技术的相关研究成果及应用现状。从废水处理的效果、稳定性及经济性等方面,对有关研究方法进行了分析和对比。分析表明,物理化学方法存在成本高、二次污染严重等缺点;由于该类废水可生化性差,单独使用传统的生物治理方法存在处理效率低、效果不稳定等问题。氧化技术与生物技术的联用有助于兼顾氧化技术处理效率高、生物处理经济性好的优点,可望实现该类废水的经济有效治理。

Development of Technology for the Treatment of Wastewater Contaminated by Nitro-aromatic Compounds

Efficient and low-cost technologies were attractive for the treatment of wastewater contaminated by nitro-aromatic compounds.To address this problem,several technological findings and applications aimed at removing this pollution have been analyzed and compared from the points of performance,stability,and economic affordability.Results showed that physicochemical methods had higher treatment costs and possibilities of causing a secondary pollution.The poor biodegradability of nitro-aromatic compounds limited the application of conventional biological techniques with the poor performance and instability when treating wastewater containing nitro-aromatic compounds.The combination of oxidation processes and microbial remediation was an attractive means for decontaminating the wastewaters,because it was both efficient and cost effective.
