摘　　要：与常规炼焦焦油脱水不同 ,工艺采用焦油脱水系统及污水焚烧处理系统联动使焦油脱水。结果表明 :焦油脱水温度为 80～ 85℃时分离效果最好。热环水中焦油去除率占 6 5 %～70 % ,冷环水中焦油去除率占 30 %～ 35 %。Different with the normal way,dehydration process adopt the way of combining the dehydrating system of coal tar with treatment system of wastewater burning.The result shows the optimized effect of dehydrating of coal tar is at the temperature of 80～85℃.The percentage of coal tar taken off in heating cycle water is 65%～70%,and 65%～70% in cooling cycle water.
