运用重复深度吸管法测量了水质自动监测站内沉砂池不同时间点的浊度，探析了浊度随时间的变化规律以及高浊度水体的静沉降特征。结果表明：在静沉降过程中，浊度随时间的变化符合指数函数曲线，浊度与沉降速率符合logistic函数关系。当浊度较低时（浊度＜50NTU），沉降速率随浊度升高而增大，且增加幅度明显；当浊度较高时（浊度＞50NTU），虽然沉降速率依然是增加的趋势，但是增加幅度趋于平缓。

In order to study variation of turbidity with time and static sedimentation characteristics of high turbidity water .the turbidity is measured in grit chamber of water quality automatic monitoring stations at different time points by McLaughlin method .The experimental results show that :in the static settlement process ,the turbidity changes over time in line with the exponential function curve , and the relationship between turbidity and sedimentation rate is in line with logistic function .When turbidity is low (turbidity <50 NTU) ,sedimentation rate increases with increasing turbidity ,and the rate of increase is significant ;when the turbidity is higher (turbidity> 50 NTU) ,though sedimentation rate is an increasing trend ,the rate of increase flatten out .
