工程依据

方法

计算捕获的原水固体、用户输入的药剂产泥量、成对输入的可选反冲洗固体及命名残余物流，再按输入的固体质量分数和密度换算湿浆。产泥系数应由项目/用户确定；不内置通用混凝剂产泥率。

Raw dry solids = plant flow (m³/d) × raw-water TSS (mg/L) × 0.001; captured raw solids = raw dry solids × capture fraction.

Chemical product mass = flow × product dose × 0.001. Chemical dry solids = product mass × the selected product or active-mass basis × the user-entered yield factor.

Backwash solids are included only when both backwash volume and TSS are entered. Other residual sources are entered as named dry-solids rows.

Combined dry solids are the sum of the entered sources. Source contribution = source dry solids ÷ combined dry solids × 100%; percentages are unavailable when the combined total is zero.

Wet sludge mass = combined dry solids ÷ sludge solids mass fraction. Wet volume = wet mass ÷ entered slurry density.

范围 / 限制

选择按商品药剂质量或有效成分质量计算产率，并声明污泥固体分数和密度。可选反冲洗参数必须成对输入。
Does not select dewatering equipment, predict cake solids, or estimate polymer dose.
No explicit return/recycle streams, dewatering, cake export, or disposal quantity is calculated; wet volume uses the entered density and mass-solids fraction. No US-unit conversion path is implemented; inputs and outputs use SI units.
No universal coagulant yield is embedded. The yield factor must be entered for the selected mass basis and supported by project or supplier data.
