臭氧化阶段溴酸盐生成影响因素的响应面研究
Studying factors influencing bromate's forming during ozonation by response surface method
摘要
Abstract
Major factors affecting the formation of BrO3 and other bromine (HOBr/OBr-) were investigated in a laboratory by the response surface method. The results show that decreasing initial bromide (Br-) concentration, ozone dosage, contact time or pH all can reduce the BrO3- formation amount. Except the contact time, the other factors also have significant effects on the bromine concentration. When the initial Br- concentration is lower than 300 μg/L, the ozone dosage decrease is the most significant impact on the generated BrO3- , which can be reduced by up to 80%. When the Br- concentration is above 300 μg/L, pH adjustment can reduce the BrO3- amount of 50% and the relative amount of ozone dosage.关键词
