摘要
黄河水的浊度与含沙量之间没有固定的比值关系。本文根据浊度与光密度的关系,提出了确定浊度T与含少量C_w的关系需要引入泥沙颗粒比表面积参数S_0,并用黄河上、下游不同河段的的不同粒度分布的泥沙或浑水进行了实测分析,得到了关系式T=a(S_n^0·C_w)~b。此式对黄河高浊度水有较好的的普遍意义,并为高浊度水投药自动控制解决了浊度仪与含沙量测定仪表两者读数的衔接问题。
The ratio between turbidity and the concentration of high-turbidity water of the Huanghe River is not constant. According to the relationship between the turbidity and light density, this article gives a new parameter So,the specific surface area of sediment to dealing with the relationship between the turbidity of raw water and sediment concentration. Based on the experimental analysis of the turbidity, the concentration and the particle size of high-turbid water with different particle size of upper and lower reaches of Huanghe River, the relationship T=a(S0nCw)bis obtained. The formula is correct in all reaches of the Huanghe River. It was clarified from the formula that the cause of changing of the ratio between the turbidity and the concentra- tion of raw water is the variety of the sediment particle size of the river. The results are useful for automatic control of flocculant dosage with the turbiditimeter and the sediment concentration-meter, especially in the range, which both reading data overlapping each other.
