方法
根据所选池体几何尺寸和运行池数计算平面面积、表面溢流负荷、停留时间、堰负荷、可选固体负荷及停运一池工况。几何与判据由用户提供；本筛选不预测沉降或去除效果，也不判定规范或法规合规。
Basin plan area uses only the selected geometry: length × width, pi × diameter squared / 4, or the entered area.
Surface overflow rate = design flow / active plan area. Volume = active area × side-water depth; detention time = volume / design flow.
Weir loading = design flow / active weir length. One-unit-out calculations use N - 1 identical basins and their remaining weir length.
Solids loading = the entered plant solids mass flow / active plan area. The same plant solids mass flow is distributed across the remaining active area for the one-unit-out case.
