浓缩型卧螺离心机用于污泥无药浓缩与澄清——污泥无药浓缩与少药脱水的展望 Concentration type horizontal scroll centrifuge is used for non- medicament purifying and concentrating for excess activated sludge —— Prospect of non-medicament concentration and less medicament dehydration for sludge 苏州高新技术开发区三环技贸有限公司莫珉珉、吴培钧江苏太仓新太酒精有限公司茅伟刚、马心如、黄颖珍 Suzhou High and New Technology Development Zone Sanhuan Technology and Trade Co., Ltd Wu Peijun and Mo Minmin Jiangsu Taicang Xintai Alcohol Co., Ltd Ma Xinru, Mao weigang and Huang Yingzhen 摘要 LWN 系列浓缩离心机为中心进料,中心出清液,全顺流型卧式螺旋卸料沉降离心机。由于物料充满全转鼓,并且全顺流,物料在转鼓内的停留时间较一般卧螺离心机要明显延长。对于厌氧污泥,剩余活性污泥等难分离物料无需絮凝剂也具有较好浓缩、澄清效果,污泥去除率 90% 以上,浓缩污泥的浓度可达 8% 左右,污泥体积减少量 80% 左右,该机可与其它脱水设备组成浓缩/脱水一体机组,既可提高脱水效率,又可节省大量昂贵的絮凝剂。该机在江苏太仓新太酒精有限公司,用于酒精废水厌氧污泥及 SBR 生化剩余活性污泥澄清浓缩分离获得了理想效果。关键词: 厌氧污泥、剩余活性污泥、浓缩、澄清、无药型、全顺流 Summary LWN series concentration centrifuge is a horizontal scroll discharging sediment centrifuge with central feeding, central discharging the purify liquor and fully fair current type. The time for the material remains in the rotating drum is longer mon horizontal scroll centrifuge obviously, because the material full fills the rotating drum and it is fully fair current type. It has the better concentrating and purifying effect without ulating agent for difficult separating material such as anaerobic sludge, excess activated sludge, and so on. The rate of sludge removing could be higher than 90%, the consistency of concentrated sludge is up to 8%, the decrement of sludge volume is about 80%. This machine can be made up a concentration-dehydration integrative machine group with other dehydration fittings. It can both raise the dehydration efficiency and save the expensive ulating agent. This centrifuge is being used for purifying, concentrating and separating the alcohol waste water anaerobic sludge and SBR biochemistry excess activated sludge in Jiangsu Taicang Xintai Alcohol Co., Ltd and got the ideal result.
