| 摘 要： | 基于2种传统管式混合器的特点，研究了苏尔士-凯尼斯（S-K）新型组合管式混合器在预氧化-微絮凝高速过滤技术中的应用，对苏尔士（Sulzer）管式混合器、凯尼斯（Kenics）管式混合器及s-K型管式混合器高速过滤出水水质进行了对比分析，结果表明，S-K型微絮凝方式对浊度、COD及TP的平均去除率比其他2种混合器混合方式的去除效果提高了5％～10％，分别为80．3％、64．76％和51．15％。S-K型混合器过滤形成的絮体能够充分利用深层滤料，延长过滤周期。

| Abstract: | On the basis of the characters of two kinds of traditional tube mixers, the application of S-K （ Sulzer ＆ Kenics） -combined new-type tube mixer in the process of pre-oxidation micro-flocculation high rate fil- tration to reclaimed water reuse was studied. The effluent performance of Sulzer-tube mixer, Kenics-tube mixer and S-K-combined-tube mixer were investigated. The results showed that the average removal efficiency of tur- bidity, COD, and TP of S-K-combined new type tube mixer were 80. 3% , 64.76% and 51.15% , which exceed the other two types of tube mixers by 5% and 10% , respectively. The micro-floe S-K-type filtration formed can penetrate through the filter layer, so it can make full use of the depth filter and extend filter operation cycle. |
