摘　　要： 研究臭氧降解方法去除城市湖泊湖水中有机污染的可行性.以广州市五个湖泊湖水为原水样,分别用重铬酸钾法和微生物法BOD快速测定仪测定臭氧降解前后湖泊水的COD和BOD值,并探讨了降解时间的影响.结果表明,臭氧降解方法可以去除城市湖泊中部分有机物质,广州市五个湖泊中麓湖COD去除率最高达49.4%,其它湖泊COD去除率30.0%～35.0%,而且臭氧降解方法还可以提高湖水中有机物的可生化性. This article studie the possibility of using ozone degradation to eliminate organic pollution of lake water. In the source water from the five lakes in Guangzhou, the method of oxidation with potassium dichromate and fast-determining BOD equipment was used to determine the values of COD and BOD before and after the experiments. Effects of the degeneration time was evaluated. It shows that some organic compounds of city lakes are removed by using ozone degradation, the removal efficiency of COD of Lu Lake is maximum 49.4%, and other lake's are between 30.0%-35.0%. It can also improve the biodegradability of organic compounds in the lake water.
