By this method of treatment the wastes are stored in a settling basin for the proper removal of solids. 當用這種處理方法時，廢水需先在沉澱池裡停留。
So it is feasible and meaningful to make the numerical simulation on the settling tank or other hydraulic building in the design of wastewater treatment project. 可見，在污水處理工程的設計中，對沉澱池或者其它水力構築物進行數值模擬是可行的，並且也是很有意義的。
Construction of footings in water by sheet pile cofferdam method and pumping water from within the dam to settling ponds before returning it to the watercourse. 施工的腳在水中鋼板樁圍堰施工方法及抽水，從山峽大壩至沉降池，然後再返回到水道。
