玻璃管附载TiO2光催化反应器去除
饮用水中微量有机物的研究 总被引:1,自引:0,他引:1
This paper introduce briefly
the mechanism of photocatalytic oxidation organic and the structure of testing reactor
with TiO2 film coatings on glass tube surface,as well as testing process of
treatment organic micropollutants in the drinking water.These results show that the
testing reactor could successfully oxidize prior pollutants of CHCl3,CCl4
and CH2-CH-Cl3,after 1 hour treatment,the removal efficiency of
these prior pollutants in the drinking water reached 95%.The reactor needs simple
equipment and less investment,and operates easily and has a quite stable performance.In
a word,this reactor is an ideal drinking water purification equipment and has a better
commercial future. 相似文献
