本研究以家庭廢水污泥灰取代部分土燒製成磁磚，使污泥得以資源化達到再利用之目的。本研究污泥先以800℃焚燒研磨成灰，再以0%、15%、30%、45%添加於黏土中素燒後，施予0.01g/cm2、0.02g/cm2、0.03g/cm2之釉藥，以溫度1050℃釉燒為磁磚。磁磚試體性質評估項目包含吸水率、燒失量、收縮率、顏色耐光性、抗酸鹼、抗折等試驗，其結果顯示家庭廢水污泥灰取代量影響釉面磁磚性質很大，而釉藥濃度影響較小。本研究亦發現污泥灰取代量45%及施釉濃度為0.02g/cm2時，可達陶質壁磚CNS之規範要求；而污泥灰取代量小於30%時，則可應用在陶質地磚上。

　　　　　In order to reclaim sewage sludge fully, part of the clay was replaced by incinerated sewage sludge ash to make glazed tiles in this study. Sewage sludge was incinerated into ash at 800℃. This tile specimens were manufactured by adding four different amounts of incinerated ash, 0%, 15% 30%, and 45% tiles, which were then fired at 1,050℃ to sinter glaze into tile specimens. Tests such as water absorption, weight loss on ignition, firing shrinkage, ageing resistance, acid-alkali resistance, and bending resistance were performed to assess propertiles of tile specimens. The results showed that the addition of sewage sludge ash affects the properties of the glazed tiles much. It is found that, when the amount of sludge ash was up to 45% and the glaze concentration was 0.02g/cm2, the sludge ash glazed tiles meets the requirement of CNS standard for will tile earthenware. Furthermore, the floor tile earthenware could be manufactured with 30% or less of sludge ash added to tiles.
