| 摘要 | A one-dimensional model for the spatio-temporal variation of solids fraction in the blanket considering both the hydrodynamic dispersion and the convection effects was proposed in this study. The model equation was a wave equation whose solution presented shock-wave like characteristic. The model output predicted that the distribution of the solids fraction in the blanket would, firstly, evolve to a uniform distribution at a lower solids fraction. Afterward, the blanket would compact itself to another uniform distribution at a higher solids fraction. Experimental works with synthetic raw water coagulated with PACl suspended in a lab-scale suspended bed confirmed the theoretical predictions. The solids flux plot was constructed with underdosed, optimal and overdosed suspensions. Change in coagulant dose would affect the blanket height and the response time. The solids flux curve was shifted accordingly. The “optimal’ operational condition for the upflow suspended bed that produced the lowest effluent turbidity was identified and discussed. |
