摘　　要：①目的探讨焦化废水中有机毒物的去除方法。②方法在焦化废水中加入催化剂粉末，在紫外光照射下鼓入空气。③结果该方法可将包括多环芳烃（ＰＡＨ）在内的所有有机毒物和颜色有效去除。最佳光催化条件是：催化剂浓度０．３７５％，空气鼓入量３７５ｍｌ·ｍｉｎ－１·Ｌ－１，反应温度６０℃，ｐＨ值为２，反应时间６０ｍｉｎ．影响处理效果的主要因素是ｐＨ值、温度和时间。④结论紫外光催化氧化法较普通光氧化法具有去除能力强、反应迅速的特点。Objective To search for methods of removing toxic organic substances in coking waste water. Method Co king waste water were processed with catalyst and bubbling air under ultraviolet illumination. Result All toxic organic substances including polycyclic aromatic hydrocarbons and color were removed from the waste water. The best photooxidation conditions were: 0.375% catalyst, air blowing rate 37.5 ml·min -1 ·L -1 , reaction temperature 60℃, pH 2 and reaction time 60 min. The main factors affecting the results were pH value, temperature and time. Conclusion The results suggest that this is a better and promising method with strong clearing ability and rapid reaction rate.
