摘　　要：在分析黄河泥沙特性及泥沙对水环境影响的基础上,分析以往及现有COD监测方法对黄河水的监测中存在的主要问题,在此基础上,提出了多沙河流COD监测的改进方法。在该方法中,引入泥沙非降解COD值的概念,并用试验方法建立黄河下游泥沙非降解COD值的估算公式。多沙河流COD监测改进后的方法简单易行,准确度较高,其测定结果基本能够客观地反映多沙水体受耗氧有机物污染的程度。Based on the analysis of the characteristics of sediments in the Yellow River and the impacts of sediments on the water environments,this paper analyzed the primary problem which exists in monitoring COD in Yellow River with the prevenient and current monitoring methods.According to which,an improved method of monitoring COD was put forward.In this method,the concept of non-attenuation COD value of sediment was introduced and the computing formula of the value in lower reaches of the Yellow River was got by experimentation.The experiments showed that the improved method was simple and implemented easily.The accuracy of the method was high and the determining results could reflect basically the degree of pollution caused by the oxygen-demanding organic matters in sediment-laden water.
