高浓度有机废水中总有机碳的测定方法试验研究

Measurement Experiment Research on TOC in High Concentration Organic Sewage

文章探索了测试高浓度有机废水中总有机碳(TOC)的测定方法。高浓度有机废水经过15倍稀释后测定TOC,获得了线性方程:COD(mg/L)=4.9524TOC(mg/L)+220.24,R=0.993,相关性良好,表明测试具有比较高的精确度。TOC指标衡量废水的污染程度比COD具有更多更好的优越性,预测今后几年在我国高浓度有机废水处理行业中将会得到越来越多的应用。

The TOC measurement in high concentration organic sewage was explored in the paper. When the high concentration organic sewage was diluted 15 times, the equation was： COD（mg/L）=4.9524TOC（mg/L）＋220.24, R=0.993, relationship of the equation was good. This approved that the test was quite precision. Using TOC to describe the polluted degree of sewage is much better than COD. It could be forecasted that in the later years TOC will be more and more used in the high concentration organic sewage treatment industry.
