The sludge can be regenerated to general bricks for room compartment uses as well as pavement purposes with high water permeable characteristic. In the past two years, our researches have been focused on the development of typical bricks produced using the sludge. It is our intention to develop high water permeable bricks that are used for pedestrian pavement. With wide application of this eco-brick in urban area, the storm runoff and heat-island effect can be significantly reduced due to the increase in surface infiltration. The experimental design studied the composition of sludge and ash and investigated the brick compressive strength and hydraulic conductivity. The results have shown that a 80/20 of sludge/ash, 1150oC and 360 min heating period can generate a eco-brick with a compressive strength of 256 kg/cm2 with hydraulic conductivity of 0.016 cm/s. The brick with these properties are able to be used in most applications. 無害工業廢水與淨水污泥具有資源化再利 用潛能,特別是可以將之製造為磚成品如 一般隔間磚、人行磚及環保透水磚。本研 究團隊過去二年之研究著重探討將工業廢 水與淨水污泥資源化再利用為一般隔間磚 與人行磚,今年則以淨水污泥與焚化底灰 製造出具滲透性之舖面磚,俾可應用於增 加都市透水面積,減輕都市暴雨逕流,調 節都市熱島效應。實驗依污泥與底灰之添 加量的不同探討透水磚燒失量、體積收縮 率、密度、抗壓強度特性,抗壓強度會隨 著底灰添加比例的增加反而逐漸減緩之情 形,但透水係數則增加,因此以淨水污泥 佔80%之配比、燒結溫度1150℃、燒結時 間360 分鐘較適合,在此實驗條件下所得 透水磚抗壓強度為256 kg/cm2,透水係數 0.016 cm/sec,已具優良之實際應用規 格。另比較不同來源之焚化底灰,其燒結 體之物性基本上類似,因此以淨水污泥中 添加底灰製作透水磚為一可行之資源化方 法。 |
