摘要(Abstract)：

为探究PM/BS协同混凝沉淀对给水厂排泥水回用中有机物去除影响，以赣江南昌段南昌某水厂排泥水为研究对象，系统优化排泥水回流方式(直接回用与上清液回用)及预处理方法(PM+C/S、BS+C/S、PM/BS+C/S)，并构建PM/BS+C/S协同工艺，探究其对排泥水上清液回用中有机物去除情况。结果表明，排泥水直接回用、上清液回用均能降低沉后出水有机物含量，其中排泥水上清液回用对UV_(254)和DOC去除优于排泥水直接回用; PM/BS+C/S对有机物的去除优于C/S、PM+C/S、BS+C/S，该体系具有强化混凝的作用;再将PM/BS+C/S用于对给水厂排泥水上清液回用中有机物的去除，在PM和BS投加量为30μmol/L和150μmol/L，排泥水上清液回流比为5%时，对有机物去除率最大，该工艺为给水厂排泥水安全回用及有机物深度控制提供了技术支撑。
