摘要
针对炮弹销毁废水TNT、CODCr及色度含量高、水质稳定、难以降解的特点,在实验室试验的基础上,采用Fenton氧化-活性炭吸附的集成技术,进行了现场的实验研究,重点分析研究了影响Fenton氧化效果的主要因素,确定了最佳的运行参数,即c(H2O2)=0.05 mol/L,c(Fe2+)=1.80 mmol/L,pH=3.5,反应时间t=12 h。实际生产运行表明,经Fenton氧化后,TNT可有效去除80%,CODC r去除率为84%,经活性炭吸附后TNT<1 mg/L,CODC r<50 mg/L,出水水质稳定,完全达到冷却水回用标准,实现了污水的零排放。
In view of the characters with high TNT,CODCr and chromaticity,water quality stable and difficult treatment in ammunition destroyed wastewater,based on the foundation of laboratory test,the scene experimental study has been conducted,by using the integrated technology of the Fenton oxidation-activate carbon adsorption,the main factors to effect Fenton oxidation were analyzed,the best operation parameter was determined,namely c（H2O2） =0.05 mol/L,c（Fe2＋） =1.80 mmol/L,pH=3.5,reaction time t=12 h.The actual production operation indicated that,after the Fenton oxidation,TNT and CODCr can be removed by 80% and 84%.After active carbon adsorption,TNT1 mg/L,CODCr50 mg/L,the treated water quality was stable,the cooling water reused standard can be achieved completely,the sewage zero discharge can be realized.
