摘要:
采用溶胶-凝胶溶液浸涂法制备TiO2纳米材料,将其负载于全透光类玻璃球体,并用其对城市生活污水原水和生物二级处理水进行处理.利用紫外灯作为光源,探究不同涂裹次数及不同反应容器光学性质对废水处理效率的影响,并观察TiO2薄膜的重复使用效率.研究结果显示,TiO2薄膜对原水中的氨氮和化学需氧量(chemical oxygen demand, COD)去除率可分别达到23.13%和68.68%;对生物二级处理水的氨氮和COD去除率可分别达到43.95%和78.95%;涂裹次数增至5次,去除率可比涂裹1次时提高4~5倍;以内壁反光材料为反应容器时处理效果无显著性差异(P>0.05); TiO2薄膜重复使用4次时,对氨氮仍有29.9%的去除率,且仍可使COD降低35.09%左右.研究表明,TiO2薄膜是一种具有良好光催化性能且可回收利用的纳米材料.
Abstract:
TiO2 nano-materials prepared by sol-gel dipping and pulling method are loaded onto extremely light-pervious glass spheres and used for the city’s wastewater treatment on contaminant in raw water and secondary effluent. The photo-catalytic property of the TiO2 nanofilm is characterized by the degradations of organic contaminant in raw water and secondary effluent from the sewage treatment plant. The efficiency of effluent treatment under the irradiation of UV lamps is investigated under different conditions of coating cycles and optical properties of reaction vessel. The results are summarized as follows: the removal rates of ammonia nitrogen and chemical oxygen demand (COD) for raw water treated by the TiO2 nanofilm can reach up to 23.13% and 68.68%, respectively; and the removal rates of ammonia nitrogen and COD for the secondary effluent can reach 43.95% and 78.95%, respectively. After the coating cycle for the TiO2 nanofilm is increased to 5 times, the removal rates of ammonia nitrogen content and COD value are raised to 5-6 times as compared with that with only 1 coating cycle. There is no significant improvement in the treatment effect when the inner wall of the reaction container is replaced by reflective materials (P>0.05). After the coating is reused 4 times, the removal rates of ammonia nitrogen content and COD can still reach 29.9% and 35.09%, respectively. Thus, it is proposed that TiO2 nanofilm is a recyclable nanomaterial with a good photo-catalytic degradation property.
