| 摘 要： | 为评估和有效调整地表水预处理工艺的运行状况或混凝杯罐试验的混凝效果,采用一种自由沉降测定管法,对水样中颗粒物沉降速率进行测定,获得了速率分布曲线。结果表明:该方法可对颗粒物的去除率进行定量评估,及时调整澄清池的运行参数,以提高出水品质。也可对混凝杯罐试验的混凝效果、搅拌强度、混凝药剂的筛选进行评估。

| Abstract: | In order to evaluate and adjust effectively the operation condition of surface water pre?treatment process or the concretion effect of the concrete tank, adopts a method of free sedimentationmeasurement tube to mensurate sedimentation velocity of particle in the water sample and acquire therate distribution curve. The result shows that this method can make ration evaluation for the removingrate of particle and adjust the operation parameter of the settling basin in time, improve the quality ofthe water outlet, also can make evaluation for the concretion effect of the concretion tank, the intensityof churning up and the filtration effect of concrete drug. |
