日本大阪市水道局的工业用水系统城东净水厂,采用的是脉冲澄清池,在使用过程中,曾产生过如下问题:1.因泥渣层厚,泥渣新陈代谢慢,在池内停留时间长(20～30日)时,不仅对细微絮凝体的凝聚吸附能力差,而且由于脉冲影响,使一些大块絮体形成的泥渣,再次分解成微小絮体,使沉淀速度降低,因此,当水温或水量稍有变化时就上浮,使处理水恶化而造成泥渣膨胀。
The water purification plant of the City Water Works Bureau of Osaka City, Japan, uses a pulse clarifier. During its use, the following problems have occurred: 1. Due to the thick mud layer, the metabolism of the sludge is slow, and the residence time in the pool When it is long (20 to 30 days), not only does it have poor agglutination and adsorption capacity for fine floc, but due to the influence of the pulse, the sludge formed by some large flocs is once again decomposed into small flocs and the sedimentation rate is reduced. Therefore, When the water temperature or the amount of water slightly changes, it floats, causing the treated water to deteriorate and cause the sludge to expand.
