本文从影响絮凝过程的主要参量出发,通过试验资料分析,提出以GTR_e 0.5作为絮凝池的综合指标。该指标较好地描述了几何相似系列絮凝池的絮凝效率与包含絮凝池边界因素在内的诸参量之间的关系,有可能作为小型试验结果推广放大和搅拌试验控制的依据。这一指标的适用性已在几种流型的小型设备上得到证实,但如何用于工程实际尚待进一步研究。
In this paper, starting from the main parameters affecting the flocculation process, through the analysis of test data, we propose to use GTR_e 0.5 as a comprehensive indicator of the flocculation tank. This index better describes the relationship between the flocculation efficiency of a geometrically similar flocculation tank and the parameters including the boundary factors of the flocculation tank, and may be used as a basis for the promotion of amplification and mixing test control as a result of small-scale testing. The applicability of this indicator has been confirmed on several flow-type small devices, but how to use it for engineering still needs further study.
