【摘要】 通过实验，测定了在标准苯酚中用不同体积分数的二氧化氯，在不同温度、作用不同时间后的除酚效果，得出在２５℃左右，达到排污标准最佳条件为φ（ＣｌＯ２）为１／１００００，作用时间为３～４ｈ，φ（ＣｌＯ２）为１．５／１００００，２～３ｈ；在３５℃左右，相应１／１００００时为２～３ｈ；这样含酚废水不必做质量浓度上的特殊处理，可根据温度不同调整二氧化氯体积分数和作用时间。并根据此结果测定了不同φ（ＣｌＯ２）除废水中酚的实际效果。结果显示，此法适于含酚较低的废水除酚和作为含酚较高的废水的三级处理更多还原

【Abstract】 By experiments,the effects for ClO 2 to remove phenol in the standard phenol solution under different conditions (different consistency of ClO 2 at different temperature and reaction time) were investigated:at the temperature about 25 ℃,the consistency of ClO 2 1/10 000,3～4h;1.5/ 10 000 ,2～3 h;at the temperature about 35 ℃,1/10 000,2～3 h;can reach the standard of removing the waste in water.Thus,the waste water containing phenol need not to harness and may adjust the consistency of ClO 2 and the time of reaction according to the different temperature.Using above result the actual effect for the ClO 2 to remove the phenol in waste water was investigated.Using ClO 2 to remove the phenol is suitable for the lower consistency phenol in waste water and the third harness for the higher in waste water.更多还原
