摘要
以TiO2为催化剂,采用远紫外光催化法对餐饮含油废水进行预处理,研究光照时间、油脂浓度、pH、TiO2各因素对其处理效果的影响。结果表明:光催化可以大幅降解油脂。光催化氧化技术正交实验表明,各影响因素对油脂去除率影响程度不同,光催化技术可以有效处理餐饮废水,可作为后续生物处理的预处理技术。
The performance of UV（185nm）/TiO2 combined process in the pretreatment of the effluents from restaurants which contain high levels of oils was investigated.The main factors,such as reaction time,grease concentration,pH and catalyst concentration,affecting the photocatalytic was studied.The test results showed that the photocatalytic oxidation method can greatly removal the initial grease.Therefore,this process may be considered as an efficient alternative for the pretreatment of the oily wastewater from restaurant.
