磁介质混凝沉淀技术的进展与创新

Progress and Innovation in Magnetic Medium Coagulation and Sedimentation Wastewater Treatment Technology

在水处理过程中加入惰性重介质微粒以加速混凝和沉淀过程、高效去除总磷、SS和COD的重介质混凝沉淀技术(亦称磁混凝)正逐步被接受,并被广泛应用于污水处理工程,特别是提标改造工程项目。投加磁性重介质粉的混凝沉淀技术也被简称为磁介质混凝沉淀技术或磁混凝。作为一项新兴技术,相关的协会标准即将正式发布实施。文章简要介绍了该技术标准的编制情况,以及涉及该技术的创新(磁介质连续投加装置、解絮机和兼氧重介质活性污泥反应器)。

Magnetic Medium Coagulation and Sedimentation Wastewater Treatment Technology,called as magnetite separation or magnetic coagulation,is being accepted by more and more technicians in recent years,and applied in the sewage treatment engineering projects so as to effectively remove Total Phosphorus,SS and COD.As one kind of emerging technology,the relevant association standards are to be formally released and implemented very soon.This paper briefly introduces the formulation of the technical standard and the innovations related to it(Continuous Magnetic Medium Feeding device,Floc Pulverizer and Activated Sludge Reactor with Dense Medium).
