摘要: 项目以取至杭州四堡污水生活污水处理厂二沉池未被硝化的活性污泥,在采用溢流口Φ12mm,底流口为Φ6mm的口径的结构下,达到了很好的分离浓缩效果,溢流浆液浓度16.7g/L,底流浆液浓度为5g/L,固液分离效率在90%以上,为旋流器在污水分离中的应用提供了有力的依据。 关键字: 水力旋流器 活性污泥 分离浓缩 回流比 絮凝剂 Abstract Activated- Sludge system is widely used in the process of disposal sewerage, So,We have to keep a stated concentration of suspended solids(SS) in the aerated grit charmber, Also to keep a stated concentration of microbe,So we need to concentrate and recycle flow of sludge,Now,we mostly use secondary
