沉降

• Consolidation settlement occurs mainly in clays or silts .
  压缩沉降主要出现在粘土或粉沙中。
• They sediment toward the bottom of the centrifuge tube at a velocity .
  它们以某一速度向管底方向沉降。
• Separation is obtained by means of a series of mixers and settlers .
  靠混合器及沉降器的手段来实现分离。
• Typically these sludges settle rapidly but do not compact very well .
  这些污泥一般沉降迅速，但并不很紧密。
• The supply of sediment is insufficient to offset the rate of subsidence .
  沉积物的补给不足以抵偿沉降的速率。
• Central deposition of particles is favored by rapid and shallow breathing .
  轻向快速的呼吸有助于粒子的中心沉降。
• Additional settling overnight reduced the residual iron to essentially zero .
  再经一夜的沉降，残余的铁可降到近乎没有。
• Figure 9-1 is a simplified representation of a horizontal simple gravity settling chamber .
  图9-1是简易卧式重力沉降室的简图。
• The settling precipitates can also entrap colloids which it passes bringing them down .
  正在沉降的沉淀物也能夹带胶体使其沉淀。
• The setting velocity of a particle directly characterizes its reaction too flow .
  单颗泥沙沉降速度直接表现出它对水流的反作用。
