By this method of treatment the wastes are stored in a settling basin for the proper removal of solids. 当用这种处理方法时，废水需先在沉淀池里停留。
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. 可见，在污水处理工程的设计中，对沉淀池或者其它水力构筑物进行数值模拟是可行的，并且也是很有意义的。
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. 施工的脚在水中钢板桩围堰施工方法及抽水，从山峡大坝至沉降池，然后再返回到水道。
