Abstract: Based on the analyses on the source, the water quality and the present situation of the treatment of diazodinitrophenol 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 single 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.

Key words: diazodinitrophenol(DDNP), COD, wastewater treatment
