摘要
以可在线产生O3的反应器为依托 ,变换反应器中的不同工艺条件 ,分别对UV、O3、UV/O3、UV/在线O3等不同工艺条件对总细菌数、E .coli的杀灭和对微污染物 2 ,4 二氯酚的降解规律进行研究 .结果表明 ,UV/O3可以有效杀菌和降解微污染物 ;在循环实验中 ,反应器水流速在 40 0L·h- 1时 ,该反应器可有效产生在线O3,其在线O3对杀菌和除微污染均有一定的增效作用 .实验证明 ,UV/O3复合处理是一种很有前景的饮用水杀菌、除微污染的技术 .
A type reactor with on line O 3 was used to do further research of the disinfection of total bacteria, E.coli and degradation of 2,4 DCP. The result was obtained in the following conditions. Only UV radiation, O 3 applied by other machine and by the reactor itself, and other conditions were changed to study the disinfection and degradation. The result showed the satisfied effect of disinfection and degradation would be achieved by using UV/O 3 applied outside and when the flow rate was about 400 L·h -1 , on line O 3 could be produced and make high efforts to enhance disinfection and degradation. The method of UV/O 3 was a promising technology in the treatment of drinking water.
