摘　　要：污水扩散器排放流量低于一定值时,由于波浪运动会导致环境水体的压力场发生变化从而引起部分竖管没有污水出流或很少,海水会经由扩散器出口侵入扩散器系统。本文根据已建成的上海市污水治理二期工程资料为依据,采用数值计算(其中阻力系数由实验得到)的方法,研究在波浪因素的影响下污水扩散器出流量变化。When the flow of the sewage diffuser is below a certain value, the wave motion can change the Pressure field of the environment water which leads to little or no sewage flow from a part of the verticals. Water invades the diffuser system by its outlet. According to the documents of Shanghai Sewage Treatment Project Ⅱ which has been completed, the numerical calculation （of which drag coefficient by experiment） method was adopted to study the changes of the diffuser flow under waves impact.
