原水设计基准与变异性分析

方法

通过明确的数据映射、删失值规则、加权统计、分位数和用户选定的设计边界汇总实测原水记录。“可计算”仅表示数值与解析就绪；结果不证明物理合理性或法规合规，也不预测未来原水状况。

Percentiles use Hyndman–Fan Type 7 linear interpolation. Flow-weighted sample mean uses Σ(CᵢQᵢ)/Σ(Qᵢ). Volume-weighted interval mean uses Σ(CᵢQᵢΔtᵢ)/Σ(QᵢΔtᵢ) only with a mapped explicit positive duration. Calculation-ready data passed numerical and parsing rules; numeric validation does not confirm physical plausibility of user-defined parameters or units. The report describes observed records and user-selected design assumptions; it does not predict future water quality, establish regulatory compliance, or select a treatment process.

范围 / 限制

• 分析观测样本、Type-7 分位数、按流量或持续时间加权的汇总、月度与工况案例，以及用户选定的设计边界。本工具不预测未来原水状况。
