【摘要】 表面活性剂可以提高污泥发酵产生的挥发性脂肪酸的产量。经过污泥水解发酵产生的挥发性脂肪酸,既能作为生物除磷系统所需的优质碳源,使城市污水达到稳定深度除磷的要求,又减少了剩余污泥对环境的污染。将城市污水厂污泥生物转化为挥发性有机酸并用于生物除磷,丰富了污水生物处理和污泥处理与资源化等研究内容。更多还原

【Abstract】 The volatile fatty acids(VFAs) production increase significantly in the presence of surfactant.During the process of hydrolysis and fermentation of the sludge,the VFAs are produced,which are good carbon source for biological dephosphorization.At the same time,the pollution of sludge to the environment is reduced.Using the VFA biologically produced from sludge in the municipal sewage treatment plants for biological dephosphorization enriches the research of biological treatment and reuse of sewage and sludge.更多还原
