高锰酸钾预氧化后地表水中三氯甲烷生成量的预测模型研究

Study on Prediction Models for Quantification of Trichlormethane Produced in Potassium Permanganate Preoxidation of Surface Water

在饮用水处理中，适当地采用高锰酸钾预氧化可以降低水中的三氯甲烷生成量。本文研究了影响三氯甲烷生成量的因素[1]．如反应时间、反应温度、反应初始pH值以及总有机碳（TOC）等，并以这些影响因素为参数通过一元线性回归等数学方法，建立了各影响因素下三氯甲烷生成量的子模型和综合预测模型。

In surface water treatment,applying potassium permanganate to pre-oxidation instead of prechlorination may reduce the formation of trichlormethane. Such factors as reationtime, temperature, initial pH, TOC,etc,which have been recognized as the main factors werestudied in this paper. Taking these affecting factors as variables and considering different factors,linear methods was used in arriving at the sub patterns and comprehensive patterns forthe prediction of the quantity of trichlormethane produced in potassium permanganate oxidat ion.
