摘　　要：利用造粒型高效固液分离装置进行了西安西郊热电厂冲灰废水处理再生的现场试验研究。在总水力停留时间小于 10min的条件下 ,处理水浊度达到 3NTU以下 ,分离污泥在装置内浓缩1h以上 ,污泥含水率即可降到 85%以下。装置抗冲击负荷能力强 ,操作灵活 ,能满足连续处理和间断处理两种运转的需要。A high efficiency solid/liquid separator was developed using fluidized pellet bed technique and used for the treatment of ash washing suspension in Xi'an Xijiao Thermo Power Plant. Within a hydraulic retention time of l0 min, the high concentration suspension was efficiently purified to turbidity lower than 3 NTU. After thickening for 1 h, the separated sludge could reach moisture content as low as 85%. The separator is able to resist sudden increase in flow rate and can meet the needs of continuous and intermittent operation.
