| Abstract: | Diazodinitrophenol(DDNP)is a good explosive.Development and research of the DDNP wastewater treatment in industries are summarized,and micro electrolytic treatment of DDNP wastewater is investigated.The micro electrolytic process can effectively remove COD Cr and color from the DDNP wastewater.The removal rate of COD Cr in water can be over 80% and the colority can reach 0.Conditions for getting an optimum treatment effect are reaction temperature 25-30 ℃,air blast volume 40 L/h,retention time 48 h,V(Fe)∶V(C)=(1.1-1.5)∶1,and pH value 9-10 in the neutralization tank.It indicates that COD Cr removal effect of DDNP wastewater is very good. This pretreatment process can improve biodegradibility of the wastewater and is beneficial to the follow-up biochemical treatment. |
