摘　　要：本研究基于对二硝基重氮酚工业废水的来源、水质及处理现状的分析,提出了采用电化学与化学相结合的方法处理二硝基重氮酚废水的机理和工艺流程。以COD的去除率为研究指标,通过单因素实验重点研究了电解和氧化对废水处理效果的影响,得出较为合理的废水处理工艺。实验结果表明,在最佳实验条件下,COD的去除率高达93.0%以上,经该工艺处理的二硝基重氮酚废水可以达到国家规定的排放标准,处理成本为20.00元/m3。该工艺对其他硝基酚有机物废水的处理有一定的借鉴意义。Based on the analyses on the source, the water quality and the present situation of the treatment of diazodini- trophenol industrial wastewater, mechanism and technological process of treating diazodinitrophenol wastewater were studied by the comprehensive electrochemical and chemical method. The removal rate of COD in wastewater was taken as the norm of the investigation, and the effects of some factors on the removal rate were thoroughly studied by the sin- gle factor experiment. The reasonable wastewater processing craft was confirmed under both the eletrolysis and oxidation conditions. The results showed that the COD removal rate of diazodinitrophenol wastewater increased up to 93.0% under the optimum conditions, which could all meet the national emission standards. The treatment cost was 20. 00 RMB/ m3. This method could provide references for the nitro-phenolic organic wastewater treatment.
