中文摘要：

结合GB50014-2006（室外排水设计规范》分析集水池容积计算过程，明确了集水池容积与水泵机组自动控制之间的关系及水泵选型过程，最后结合实例给出集水池容积经验法计算依据，为工程快速计算提供理论依据。

英文摘要：

Writer give the calculation process about collecting tank volume in WWTP by Code for Design of Outdoor Water Supply Engineering （GB 50014-2006）, give a clear relationship between the collecting tank volume and water pump unit that is controlled automatically,and give a process of selecting pump model. In the end, summed up the collecting tank volume calculation method on the basis of examples of calculation, which provides the basis of rapid calculation for engineering.
