摘要： 通过对吉林省四大水系的主要河流在2005~2006年内采样,测其高锰酸盐指数(PV)、化学需氧量(COD)和总有机碳(TOC),用最小二乘法对PV—TOC、COD—TOC和COD—PV进行线性回归,并进行相关关系的显著性检验,建立吉林省四大水系主要河流PV—TOC、COD—TOC和COD—PV的定量关系模型。结果表明,吉林省四大水系主要河流中PV—TOC、COD—TOC和COD—PV之间均具有显著的线性相关关系,不同水系的线性相关关系之间存在一定的差异。

Abstract: Water samples were taken from four main river systems, i.e. Songhuajiang River system, Tumenjiang River system, Yalujiang River system and Liaohe River system, in Jilin Province in year 2005 and 2006, and the permanganate values(PV), chemical oxygen demand(COD)values and total organic carbon(TOC)values were measured for these samples, respectively. The quantitative relationships between PV and TOC, COD and TOC, and COD and PV values of water samples collected from the four river systems were analyzed using the linear least square regression method and the significance levels were also tested. Based on these analyses, the models that described these relationships were also established. The results indicate that there are significant linear correlations between PV and TOC, COD and TOC, and COD and PV values of the four river systems. Due to the different location and the different composition, these relationships between PV and TOC, COD and TOC, COD and PV values of different river systems are distinctive. Comparatively, PV value is more suitable to describe less polluted water while COD value is more suitable to be used for polluted water, but TOC value is the best one of the three parameters which can reflect the pollution condition of the water samples more factually.
