中文摘要 | 本文探討了三種不同污泥的定壓壓榨特性,尤其著重於壓榨最後階段所發生的三 階壓榨行為。 在此我們透過 Chang and Lee ( 1998 )所提出之修正 Terzaghi-Voigt 流 變模型解析壓榨過程,並求出模型中的各個參數。實驗結果顯示,三階壓榨普遍存在於含有 大量結合水的污泥中,而壓密壓力與化學調理都會改變污泥內之水份分佈與三階壓榨比例。 在此我們也比較了修正前後的模型分析結果。 |
英文摘要 | This work investigates the constant-pressure consolidation characteristics of three different sludge samples, with particular emphasis on the ternary consolida. The Terzaghi-Voigt rheological model modified by Chang and Lee (1998) is also applied to interpret the data and, in doing so, to evaluate.the model parameters. Experimental results indicate that the ternary consolidation stage commonly found in sludge contains a large amount of bound water. In addition, consolidation pressure and polymer conditioning markedly affects the moisture distribution. Results obtained from conventional analysis are also compared with those of the modified model. |
