部分回流溶气气浮法溶气系统的设计

溶气气浮法是在待处理的水中通入大量密集的微细气泡,使其与杂质、絮粒互相粘附形成整体比重小于水的浮体,从而依靠浮力上至水面,以完成固、液,液、液分离的净水方法。介绍了溶气系统的回流比和需气量具体确定方法,工程实例表明,用该方法设计的气浮设备溶气效率高,效果稳定。

A design method of dissolved air system of part circumfluence dissolved air floatation

Dissolved air floatation is that air is dissolved under pressure in the liquid which is then released to atmospheric pressure in tube . As the microscopic air bubbles come out of solution in cell , they attach to the suspended solids in the surface in liquid , causing them to floatation to the surface, then solids are separated from liquid. The article puts forward a method of calculating the required air flow and the circumfluence rate. The engineering example show that the air floatation that designed by ...
