摘要
提出了一种基于臭氧协同紫外(O3/UV)在线检测水体化学需氧量(COD)的方法,建立了以臭氧协同紫外的高级氧化体系对水样进行氧化消解,利用多个传感器信息组合来测定水体COD的方法,通过待测水样所消耗臭氧的量来计算出水样的COD。与传统的COD测定方法相比,具有操作简单方便、消解时间短、运行成本低、无需添加任何化学试剂、不会产生二次污染等优点,具有很好的推广应用价值。
We propose a method of on-line detecting the chemical oxygen demand( COD) in water and digests water samples based on an advanced oxidation system which combines ozone with UV. The COD in water can be obtained by the amount of ozone consumption according to the multiple sensor information combination.Compared with the traditional method,the method has been proved with easier operation,faster digestion,lower operating cost,no secondary pollution and no more chemical reagents to be added. Therefore,it has a great promotion and application value.
