摘　　要：水力负荷周期是污水快速渗滤处理系统中最关键的运行参数。本研究在面积为８０ｍ２的啤酒废水现场中型试验中，分别得出了淹水期入渗速率递减曲线和落干期入渗速率恢复曲线，它们可分别用指数方程和对数方程来表达。据此提出了一种以追求最大水力负荷为目标时水力负荷周期的定量设计方法。将其应用于该次试验后得出的结果为１．７８ｄ淹水、２．７７ｄ落干。计算结果与实测结果比较表明，该方法是可行的。ydraulic load cycle is the most important operation parameter in rapid infiltration treatment system of waste water. The decrease curve and recovery curve of infiltration rate in flooding and drying periods.are obtained from the in situ test with the area of 80 m2 and flooded with brewery waste water. The curves can be expressed with exponential and logarithmic equations respectively. A quantitative method is proposed to determine the hydraulic load cycle with maximum hydraulic load. The calculated result is 1. 78 days flooding and 2. 77 days drying,very similar with the test results.
