摘要
二硝基重氮酚 (DDNP)是一种优良的起爆药。概述了DDNP废水治理技术的发展及在工程中的应用 ,研究了微电解处理工艺。实验表明 ,微电解法在合适的条件下〔反应温度为 2 5～ 30℃ ,微电解反应时间为 48h ,V(Fe)∶V(C) =(1 1～ 1.5 )∶1,曝气量 40L/h ,中和池pH =9～ 10〕对DDNP废水进行预处理有较好的效果 ,能降低废水的CODCr和色度 ,改善废水的可生化性 ,有利于后续生化处理。出水CODCr降低 80 %以上 ,色度几乎为 0。
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.
