1973年,我们教研室对脉冲澄清池,廓道式悬浮澄清池以及各种斜管(板)沉淀池进行了比较、研究分析和总结,提出了“悬浮型斜管澄清池”的设想,然后和上海南市水厂协作进行了半生产性的试验。“悬浮型斜管澄清池”的特点是利用脉冲澄清池的穿孔配水管,加入字稳流板的配水系统;其上采用2米以上的高浓度的悬浮泥渣层;在清水区中加装斜管;把混合、反应、沉淀三部分建于一个池子内。这样,不但解决了一般斜管(板)沉淀池布水不均匀和由反应池到沉淀池矾花易破碎的矛盾;而且充分利用了悬浮层上部的空间;克服了一
In 1973, we compared, researched and summarized pulse clarification tanks, profiled suspension clarifiers, and various inclined tube (plate) sedimentation tanks. We proposed the idea of a “suspended inclined tube clarifier” and then Shanghai Nanshi Waterworks conducted a semi-productive experiment. The characteristics of the “suspended inclined tube clarifier” are the use of perforated water distribution pipes for pulse clarifiers, and the water distribution system for the word steady flow plates; the high concentration suspended sludge layer of 2 meters or more is used; Oblique tube; the three parts of mixing, reaction and precipitation are built in a pool. In this way, not only the inconsistency in the distribution of water in the general inclined pipe (plate) sedimentation tank and the breakage of the flowers from the reaction tank to the sedimentation tank is solved, but also the space in the upper part of the suspension layer is fully utilized;
