摘要
光催化氧化技术已被广泛用于降解各种难降解有机物,在去除造纸废水的毒性和色度方面,比传统的生化处理法具有更高的优越性,且能提高废水的可生化降解性。作者就催化剂的性质、投加量、光催化体系的pH和外加氧化剂等因素对光催化降解造纸废水的影响及反应机理进行了讨论。
Photocatalytic oxidation process, which is widely used to degrade lots of refractory organic matter, is more excellent than biological process in the removal of toxicity and chroma of papermaking wastewater, and the biodegradability of the wastewater will be improved after photocatalytic degradation. Some influential factors, such as the properties of catalyzer, its dosage, pH of photocatalytic system and extra oxidant on photocatalytic degradation, of papermaking wastewater, as well as the reactive mechanism of photocatalytic degradation, are discussed.
