摘要
在分析絮凝相似原则的基础上,综合前人的基础理论和研究成果,对现有絮凝控制指标G、GT、GTRe-1/2、E1t/3T、Eu、Fr等进行了综合对比,阐述了各个指标产生的理论基础及优缺点,并指出现有的絮凝控制指标在一定程度上都存在很大的局限。随着混凝理论的发展和混凝动力学研究的深入,在大量试验的基础上,迫切要求出现更符合实际、更科学的新的参数。
Based on the analysis of the similar principle of flocculation efficiency,basic theories and research results of the previous researchers were summarized to compare and analyze the existing control indexes of flocculation efficiency,such as G,GT,GTRe-1/2,E1/3tT,Eu,Fr,etc..Theoretical basis,advantage and disadvantage of each index were also discussed.With the development of coagulant theory and coagulant dynamics,there was a pressing need for some more actual and scientific new parameters through a lot of experiments.
