The sludge is passed under a vacuum pump and allows the water to pass through a discharge or recirculation drain . 用真空泵除去污泥的固体含量而该泥水则经排水渠或回流渠排出。
While a numbher of stirred-tank designs involving either internal or external recirculation of the reaction mixture have evolved in recent years . 同时,最近几年开发了一系列使反应混合物进行内循环或外循环的搅拌槽式装置。
