油田采出水中主要污染物为原油及悬浮物，这两种污染物的去除方法主要为物理法、混凝法、过滤法等。“惯性效应”理论是近两年发展起来并首先在给水处理中得到验证的理论，它将过去概念中宏观传质过程分为宏观扩散与亚微观扩散两个不同物理过程，提出亚微观扩散的动力学致因是 The major pollutants in the oilfield produced water are crude oil and suspended solids. The removal methods of these two pollutants are physical, coagulation and filtration. The theory of “inertial effect” was developed in the past two years and first verified in water treatment. The theory divides the macroscopic mass transfer process in the past into two different physical processes, macroscopical diffusion and submicroscopic diffusion, and proposes submicroscopic diffusion Kinetic reason is
