硅藻土过滤水力学

硅藻土过滤工过程中的水头损失分为两部分──清洁预涂层的水头损失和附加剂加上悬浮固支的水头损失，文中介绍了每一部分水头损失的渗透系数的确定，为硅藻土过滤器设计和过滤成本计算提供了依据。

: The water head loss of the diatomite filtration can be divided into two categories i . e. head loss at the clear precoating layer and head loss at the attached suspended solid layer. The method to determine the permeability coefficients of each part of head loss has been introduced in this paper. This will be the basis. for the design and operating fee estimation of the diatomite filter.
