| 摘 要： | 为了解吉林省典型废水的化学需氧量(COD)与总有机碳(TOC)间的相关关系及其形成机制，在对吉林省典型废水的ρ(COD)与ρ(TOC)进行测定的基础上，分析了各类废水ρ(COD)与ρ(TOC)的相关关系，研究了其形成作用和有机组分的挥发性与可氧化特征对其的影响。结果表明：所研究废水水样的ρ(COD)与ρ(TOC)间均存在显著的线性相关关系(α≤0.050)，各类废水ρ(COD)/ρ(TOC)为1.711~12.280；废水ρ(COD)与ρ(TOC)的相关关系主要由废水的有机化学成分决定，其中废水有机组分的元素组成起主导作用，有机组分的挥发性和可氧化特征对废水ρ(COD)与ρ(TOC)的相关性和比值均存在影响。

| Abstract: | Chemical oxygen demand(COD) and total organic carbon(TOC) of typical wastewaters in Jilin Province were investigated.The possibilities of establishing linear regression equations were studied through analyzing relationship between COD contents and TOC contents of wastewaters.Based on this,influences of volatility and oxidization properties of organic compounds on relationship between COD contents and TOC contents of the wastewaters were discussed via analyzing organic compounds of some wastewaters.The mechanisms of the relationship of wastewaters were discussed.The results indicated that there were significant linear correlations between COD contents and TOC contents of all the samples of the typical wastewaters(α≤0.050).The range of COD/TOC of all kinds of wastewaters were from 1.711 to 12.280.The relationship was mainly controlled by the composition of the wastewaters.Elemental composition of the typical organic pollutants in the wastewaters played a key role in determining the correlations between COD contents and TOC contents of the wastewaters.The volatility and oxidization properties of the main organic pollutants in the waters also played important but divers roles in these correlations and the ratios of COD to TOC of the wastewater samples. |
