The concept of effective density and water content were introduced to describe the physical state of the clay matrix filling between sand particles.

引入有效粘土密度和有效含水率的概念，描述石英砂颗粒之间的粘土基质的物理状态。

At the same time, the appropriate preozonation can increase the effective density of the floc, making the floc more dense and improving its sedimentation capacity.

同时，适当的预臭氧氧化能增大絮体的有效密度，使絮体更加密实，提高沉降性能。
