摘要:
以粉末TiO2为光催化剂研究了光催化技术提高聚乙烯醇(PVA)废水可生化性的可行性. 结果表明,催化剂的最佳投加量与光照时间有关,当光照时间为2 h,最佳催化剂投加量为1.38 g/L; pH对处理效果影响较大,最佳pH值范围为5~7; 光催化后PVA模拟废水中有共轭双键生成,废水B/C比则相应提高,2 h后可达0.46,已满足生化处理要求,即采用光催化-生化组合工艺时,光催化时间控制在2 h以内较为合理.
Abstract:
The feasibility of the biodegradability increase of polyvinyl alcohol(PVA)wastewater by TiO2 photocatalysis is studied in this article. The study shows that the optimum adding amount of the catalyst is related to the illumination time,such as amount of 1.38g/L to illumination time of 2 hours correspondence. The optimal range of pH value which has a great effect on removal efficiency is from 5 to 7. The conjugated bond is produced in PVA simulated wastewater during the light catalyzed reaction,and the B/C ratio increases correspondingly,which can reach 0.46 after 2 hours. The biodegradability has met the demands of biological treatment,which shows that reasonable photocatalytic time should be controlled within 2 hours during the integrated process of photocatalysis biological treatment.
