Performance of Calcium Silicate Hydrate Briquettes Produced from Fly Ash and Slaked Lime in Disposal of Wastewater

概要
- 論文の詳細を見る
Hydrothermal reaction of fly ash and slaked lime produces a porous briquette which is composed of amorphous calcium silicate, a tobermorite-like compound and hydrogarnet. It is essential for the molar ratio (calcium oxide)/(silicon dioxide) of the briquette to be 0.3 to achieve high performance in the purification of wastewater through improved microorganism-carrying ability. The chemical oxygen demand (COD_<Mn>) index in artificial, non-fecal drainage decreases more rapidly with the use of the briquettes than that without the briquettes. The macroscopic configuration of the briquettes is an important factor in the water-purification ability, although the high specific surface area of the briquettes does not affect the performance. By increasing the circulation flow rate of the wastewater, the purification performance is improved considerably.
