纳米TiO_2在脱硫废水治理中的实验研究

Experimental Study of Desulphurization Waste Water Treating by Nanometer TiO_2

叙述了采用测量原水中的Cl-,SO42-,COD,F-,S2-,色度和浊度等指标,以Cl-和SO42-作为主要测量对象,以自制掺杂N的纳米TiO2处理邯郸热电厂脱硫废水方法,确定的具有最佳去除效果的TiO2。指出,材料黏附性差时,对废水处理的效果不好。

Described methods of desulphurization waste water treating using home-made nanometer titanium dioxide to treat the desulphurization waste water in the Handan thermal power plant.In the first step,the author analyzed the original water indexes,such as Cl-,SO42-,COD,F-、S2-,the chroma,the turbidity and so on.And chose Cl-and SO42-as the main objects,which are selected to prove the efficiency of nanometer titanium dioxide,so he find out the nanometer titanium dioxide which is N doped is the best catalyst.In the experiment,he tried some kinds of load of TiO2,such as ACF,glass,and quartz sand.Pointed out the effect in water treatment is not obvious,because of its not good stick character.
