Abstract
To control the soil polluted by TNT red water in a certain area, the polluted soil was treated by thermal decomposition method,and the effect of thermal decomposition temperature, thermal decomposition time and mass of polluted soil samples on the treatment effect of TNT red water polluted soil was studied.The results show that when the temperature reaches more than 300℃, the residual organic oxygen demand in soil decreases with increasing the thermal decomposition temperature, and the color of washing water of the polluted soil samples becomes more and more shallow.With increasing the thermal decomposition time, the residual organic oxygen demand in soil decreases.With increasing the mass of polluted soil sample, the residual organic oxygen demand in soil increases.The optimal processing conditions are determined as:when the thermal decomposition temperature is 500℃, thermal decomposition time is 10min and mass of polluted soil samples is 30g, the residual organic oxygen demand in soil decreases from 15.75mg/g in the original polluted soil to 0.1642mg/g, the removal efficiency is 98.96%.GC-MS test results show that the thermal decomposition method has obvious effect for treating the polluted soil.关键词
