自 1970 年代以来，毛细管吸入时间 (CST) 一直被用作表征污泥过滤性和调节性的快速可靠的方法。污泥过滤性主要控制几乎所有各种类型的脱水设备的输出，包括：干燥床、带式压滤机、真空过滤器、压滤机和离心机。标准滤纸产生的毛细吸水压力用于从污泥中“吸”水。水通过滤纸的渗透率取决于污泥的状况和滤纸上形成的滤饼的可过滤性。CST 是从与漏斗相距标准间隔放置的两个电极获得的。水锋在这两个电极之间通过的时间构成了 CST。

毛细吸水时间知识扩展：

毛细吸水时间(CapillarySuctionTime，简称CST)的测试是表现污泥脱水性能的一个快速和可靠的方法。CST愈大，污泥的脱水性能愈差，反之脱水性能愈好。通过标准滤纸产生的毛细吸水压力用于从污泥中“吸收”水分，水分渗入滤纸的速率的改变依靠污泥的状态和在滤纸上形成的纸饼的过滤性，CST是从漏斗上的两个以标准间隔放置的电极上获取。得到的从开始到通过这两个电极间的时间即为CST。 

 

污泥毛细管吸水时间（CST）：简单来说就是污泥与滤池接触时，在毛细管作用下，污泥中的水分会在滤纸上渗透，在滤池上渗透1cm长度的时间就是CST，单位是秒。CST越大，则脱水性能越差；

英文原文：

 

The Model 304M CST is a replacement for the Model 165 CST and is now the basic laboratory CST test equipment. Electronics have been improved and the mechanical counter replaced with an LCD. It is designed and tested to comply with European and USA EMC standards.

The mains input supply can be set for either European or USA standards.

 

Capillary Suction Time (CST) has been used since the 1970s as a quick and reliable method of characterising sludge filterability and conditionability. It is sludge filterability that, predominantly, governs the output of nearly all various types of dewatering equipment, including: drying beds, belt press, vacuum filters, filter presses and centrifuges. The capillary suction pressure generated by standard filter paper is used to ‘suck’ water from the sludge. The rate at which water permeates through the filter paper varies depending on the condition of the sludge and the filterability of the cake formed on the filter paper. CST is obtained from two electrodes placed at a standard interval from the funnel. The time taken for the water front to pass between these two electrodes constitutes the CST. The force generated by capillary suction is much greater than the hydrostatic head within the funnel, so the test is independent of the amount of sludge, as long as there is sufficient to generate the CST.

 

Each Type 304 CST comes with:

CST Meter

Perspex Block Assembly

Stainless-Steel Funnels

Filter Papers (200 with 304M and 20 with 304B)
