从料浆沉降和过滤成饼两个角度同时研究过滤速率和成饼速率以及滤饼的渗透率和可压缩性，提出了更为全面的滤饼比阻关系式。证明滤饼渗透率首先和料浆的浓度及沉降速度有关，因此和料浆的预处理及料浆的化学环境密切相关。明确了滤饼都是可压缩的，其可压缩性分为两大类：滤饼中颗粒的位移、迁移和团聚颗粒的变形，由于它们的被压缩的机理不同，所以和有关因素的相关关系也不同，分析和论述了主要的关系。全文分为两大部分，相对独立。但本文不涉及滤饼的压榨
From the perspective of slurry settling and filtration into cake, the filtration rate and cake formation rate, as well as the permeability and compressibility of the filter cake, are studied simultaneously to provide a more complete filter cake specific resistance relationship. It is proved that the permeability of the filter cake is related to the concentration of the slurry and the settling velocity. Therefore, it is closely related to the pretreatment of the slurry and the chemical environment of the slurry. It is clear that the filter cake is compressible, and its compressibility is divided into two categories: the displacement of the particles in the filter cake, the migration and the deformation of the agglomerated particles. Because of their different mechanism of compression, the correlation with the relevant factors Also different, analyzed and discussed the main relationship. The full text is divided into two parts, relatively independent. However, this article does not cover the presscake press
