摘　　要：一些污水厂的巴氏计量槽,由于设计上的不合理,导致流量计量误差较大,有的甚至不能发挥流量计量作用而被弃用。结合具体工程实例介绍了巴氏计量槽的设计过程,并总结了巴氏计量槽的设计要点,以供设计人员参考和借鉴。Parshall flumes in some sewage treatment plants had a large flow measurement error due to their unreasonable design, some could not even play a role in flow measurement and were out of service. Combined with a specific engineering example, the design process of Parshall flume was introduced, and its key design points were summarized to provide a reference for designers.
