部分回流溶气气浮法溶气系统的设计

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

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。

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 ...
