【摘要】 由于火电厂燃煤煤质多变,导致锅炉排渣量和冲渣水量上升,排水浓度增高。采用传统的渣水处理装置,沉淀效果差,排放严重超标。采用DH高效污水净化器技术将直流混凝、临界絮凝、离心分离、动态过滤、污泥浓缩工艺技术有机地集成为一体,在同一罐体内快速完成对高浓度灰渣水的多级净化,使水质达到排放或回用要求。该设备的处理能力强,最高可达90 000 mg/L,废水的设备停留时间小于30 m in。
【英文摘要】 Because the coal grade for coal-fired power plant varies frequently,thus leading to increasing of ash-slag discharge and sluice of boiler and rising of discharged water concentration.when the traditional slag sluice treatment equipment were used,sedimentation effect was low,discharge exceeded standard seriously.The DH high efficiency sewage purifier technology can integrate the once-through mixing coagulation,critical fluctulation,centrifugal separation,dynamic filtration,and sludge concentration technologi...
