光催化降解对氯苯酚废水的研究

Study on Photocatalytic Degradation of the p-Chlorophenol Wastewater

研究了TiO2光催化降解对氯苯酚的影响因素。结果表明:紫外光是有效的辐射光源;对氯苯酚浓度越低,光催化降解率越高;二氧化钛的适宜浓度为200mg/L;采用曝气装置可以提高对氯苯酚降解率;pH值越低,降解率越高;助氧化剂H2O2可提高对氯苯酚降解率,H2O2的适宜浓度为15mg/L。

Photocatalytic degradation of p-chlorophenol wastwater by catalyst TiO2 is investigated. The result indicated that, the ultraviolet ray is the effective radiation photosource; The concentration of the pchlorophenol is lowly, the degradation rate is higher; The suitable concentration of TiO2 is 200mg/L;Used the aeration equip ment to enhance to the degeneration rate of the p- chlorophenol; pH value is lower, the degradation rate is higher; Added H2O2 can enhance to the p- chlorophenol degeneration rate, the suitable concentration of H2O2 is 15mg/L.
