floatation n. 1.漂??;(船的)下水。 2.【礦物】浮選(法)。 3.(公債等的)發(fā)行;(公司等的)設(shè)立;創(chuàng)業(yè);(計(jì)劃的)實(shí)行。 the floatation of a loan 籌資。 the centre of floatation 浮體的重心。 oil floatation 浮油選礦。
Dissolved air floatation is that air is dissolved under pressure is 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 th the surface , then solids are separated from liquid 氣浮就是設(shè)法在待處理液體中通入或產(chǎn)生大量密集的帶有壓力的微細(xì)氣泡,在管道以常壓下釋放,使其在池內(nèi)與雜質(zhì),絮粒互相粘附形成整體浮體,從而依靠浮力使其上浮至液面,從完成固液分離的方法
" this new treatment works has been specifically designed to take advantage of the most advanced technologies , including clarification by dissolved air floatation units and removal of ammonia and manganese by primary aerated biological filters to produce high quality drinking water , " mr ko said . to conserve water , all wash - water used for regular cleaning of filters is recycled 他說,大埔濾水廠在設(shè)計(jì)上采用最先進(jìn)的技術(shù),包括以溶氣浮選池進(jìn)行澄清工作,以及使用初級(jí)曝氣生物過濾池消除水中的氨氣和錳,以提供優(yōu)質(zhì)的食水。
