摘要
为探索湿式氧化法处理TNT红水的可行性,采用间歇式氧化装置处理TNT红水,研究了反应温度、停留时间、进样pH值和反应初始氧气压强等条件对出水COD值的影响。结果表明,湿式氧化反应温度控制在200℃为宜,在初始氧气压强为4M Pa,停留时间为10m in,进水pH值为4时,TNT红水的COD值可由初始的56 500m g/L下降到1 072.5m g/L,去除率达98.10%。
In order to study the feasibility of treating TNT red water with wet oxidation method and determine the optimum technology conditions, various parameters affecting the chemical oxygen demand（COD） value,such as reaction temperature, reaction time, pH value of in fluent and initial reaction pressure of oxygen, were investigated. The results indicated that when the reaction temperature is 200℃, residence time 10min, oxygen pressure 4 MPa, and the pH value 4, the COD value of TNT red water decrease from 56500mg/L to 1 072.5mg/L, the removal efficiency is more than 98.10%.
