污泥负荷法和泥龄法是活性污泥工艺设计的主要计算方法,这2种设计方法偏于安全、保守,以经验为主,没有反映出活性污泥工艺中生物反应机理,缺少理论支持,适用范围窄,而数学模型法才是活性污泥法设计的发展趋势,利用数学模型进行活性污泥工艺设计可以有2种方法选用:试算法和优化法。
Sludge loading method and sludge age activated sludge process, the said 2 design methods experiences as the core factor, the biological reaction methods lack of theory support, the applicable range method are the main calculating methods for the design of lay particular stress on security and conservatism, take mechanism in activated sludge process are not reflected. As of them is narrow. So, the mathematic model method is the development trend of the design of activated sludge process; using mathematic model to design activated sludge process, there are 2 methods for selection: trial and error method, optimize method.
