混凝沉淀构筑物的发展大致可分三个阶段:60年代以前,主要采用平流式、立式和辐射式沉淀池;从60年代起,各种澄清池在国内外应运而生;而进入170年代后又出现了斜管、斜板沉淀池。并由此相互结合产生“复合型”沉淀池,如澄清池中加斜管,平流池的后段加斜管(即平流—斜管沉淀池)等。在 The development of the coagulation and sedimentation structure can be roughly divided into three stages. Before the 1960s, the main types of the sedimentation tanks were the advection, vertical and radiant sedimentation tanks. Since the 1960s, various clarification tanks have emerged at home and abroad; Afterwards, inclined pipes and inclined plate sedimentation tanks appeared. And thus combined with each other to produce a “composite” sedimentation tank, such as clarification tank plus inclined pipe, the rear section of the advancing tank plus inclined pipe (that is, advection - inclined pipe sedimentation tank) and so on. in
