On basis of theoretical analysis, a concept that the efficiency of sulfur oxide absorption depends directly on the value of the reactive surface layer is proposed Experimental data are well correlated with the theoretical analysis, and a correlation describing the absorption process is introduced. By experiments, the weight fractions of the reactive surface layer of the granular limestone with definite diameters to their total weights are determined.

On basis of theoretical analysis, a concept that the efficiency of sulfur oxide absorption depends directly on the value of the reactive surface layer is proposed Experimental data are well correlated with the theoretical analysis, and a correlation describing the absorption process is introduced. By experiments, the weight fractions of the reactive surface layer of the granular limestone with definite diameters to their total weights are determined. It is found that the reactive surface layer of all those limestone granules remaining in the fluidized bed has almost the same thickness. This will enable us fo choose the optimum size of the limestone granules By Experimental method, the absorptivity of the fine limestone granules is improved, and the regeneration of the used limestone granules is also discussed.

Column settling test is currently used to do settling analysis for dilute suspensions. Theoretical settling efficiency of horizontal sedimentation tanks can be estimated. The method of analysis was first suggested by Camp for discrete-particle suspensions and then extended by Eckenfelder and O'Connor for flocculant suspensions. Their analyses are both based on settling velocities of suspended particles.Discrete particles settle in constant velocities and flocculant particales in increasing velocities. So the method of analysis is somewhat different for the two types of sedimentation.But settling column can simulate plug flow or ideal horizontal sedimentation tank directly. By analysing the column settling test data, the average concentration of the settled suspension can be obtained and then the settling efficiency can be estimated easily. While this method of analysis is applicable to both types of sedimentatian, for flocculant suspensions it is much simpler than the current method.It might be also applied to designing secondary sedimentation tank of the activated sludge process. It seems to be possible to estimate underflow concentration and sludge rerun ratio for given tank depth and detention time.

沉淀柱实验是一个估计沉淀池效率的常用实验。目前,实验数据的分析方法以悬浮颗粒的沉速为基础。因此对不粘颗粒悬浮液和粘性颗粒悬浮液采用的诠释方法是不同的。但是,沉淀柱可以直接模拟理论沉淀池;所以可以不通过沉速分析,直接依据浓度数据来估计沉淀效率。这一方法可以用于任何悬浮液,与悬浮颗粒的性质无关。

本文描述了固体颗粒在上升液流中的运动,说明了提高沉降槽产能的可能性及其限度。为了不引起泥渣积累和保证溢流的澄清度,增加沉降槽的高度是提高其产能的必要条件。用赤泥进行了间歇沉降试验,发现不同的原始泥浆高度所得的沉降曲线,在沉降初期,它们的直线段互相重合;通过各沉降曲线的临界点的切线是互相平行的。说明泥浆的原始高度不影响泥浆的沉降速度。
