中文摘要 | 廢水處理程序所產生的大量污泥往往需要甚大面積的掩埋場進行處置,為因應目前掩埋場址日益短缺的問題,必須尋求掩埋之外的處置方式。本篇論文回顧將廢水污泥利用在製造建材原料的一系列研究,包括磚塊、混凝土填充物、混凝土骨材、與似水泥物質等。在混合污泥與黏土製磚時,污泥所佔比例可達重量分率40%;製造混凝土填充物時,重量分率10%的水成份可置換為污泥灰,而不影響其強度;污泥製成的骨材可以取代混凝土內的花崗岩材質,而不影響其壓縮強度;污泥製成的似水泥物質亦可取代重量分率20%的一般波特蘭水泥,而不影響製成混合水泥之灰泥強度。本研究顯示,將廢水污泥再利用於建築材料將提供掩埋處置以外的另一技術可行方案,在此也討論各種製品的物性。 |
英文摘要 | The large volume of wastewater sludge generated requires enormous landfill space for disposal. Diverting the wastewater sludge from landfill would alleviate the shortage of landfill sites. Thus alternative applications have to be considered for the wastewater sludge diverted away from the landfills. The use of wastewater sludge for the production of construction materials is reviewed in this paper. Wastewater sludge can be used as raw materials for making bricks, concrete filler, concrete aggregates and cement-like materials. Up to 40% of sludge can be mixed with clay for structural bricks making. For use as concrete filler, up to 10% by weight of the cement can be replaced by sludge ash without affecting the strength property. Sludge aggregate made from 100% sludge can be used to replace granite in concrete without any compromise in compressive strength. Cement-like materials made from sludge can be used to replace ordinary Portland cement for up to 20% by weight to produce blended cements without affecting the mortar strength. The study reveals that the reuse of wastewater sludge as construction materials offers a technically feasible alternative for sludge disposal. The properties of each of the products are reported and discussed. |
