A Study on the Pyrolysis Model Simulation of Sludge

[[abstract]]近年來由於產業蓬勃發展、經濟之高度成長、民眾生活水準普遍提升、廢棄物排放量日益增加，加上政府進行污水下水道建設，促使下水道接管率大增，致污水處理場衍生之下水污泥量亦隨之驟增，而污泥具有回收再利用之價值，應妥善處理避免造成環境二次污染等問題。因此本研究利用熱裂解方式來探討污泥之熱性質變化情形；本研究以(1)微分法：Friedman 法；(2)積分法：Ozawa法等方法來求得污泥熱裂解不同的動力學模式，並與實驗值之各項參數比較其線性迴歸之R2值，以評估由實驗所求之熱力學動力學各參數之適用性是否良好。本研究主要以台南安平水資源回收中心之二級污泥及台南科學工業園區污水處理廠之有機污泥，將含水率控制於 A：[[abstract]]The flourishing industry highly economic growth standard of living increase and waste increase construction of sewage systems by the government and drainage rates increase have contributed the rapid surge of sludge in sewage treatment plants Due to the fact that the sludge is worth recycling it should be properly treated to avoid further pollution This research is conducted by the method of thermal cracking to explored the thermal properties of the changing sludge The methods including (1) Differentiation: Friedman method; (2) Integration method: Ozawa method and other methods are used to obtain different dynamic sludge pyrolysis model with the experimental values of the parameters of linear regression to compare the value of R2 and to analyze the applicability of the demand of the experimental kinetic parameters thermodynamics The sludge sample utilized in this research is mainly the secondary sludge from Water Recycling Center in Anping Tainan and organic sludge from Tainan Scientific and Industrial Park in Tainan The moisture is controlled as A
