Online calculation of pollutant concentration in Heihe River, EIA calculation

The formula for calculating the concentration of pollutants in Heihe River:

\(C = \frac {C_pQ_p + C_hQ_h}{Q_p + Q_h}\)

In the formula:

C——Black sap flow concentration, mg/l

C_p——the concentration of wastewater pollutants, mg/l

Q_p——discharge of wastewater, m³/s

C_h——the concentration of pollutants upstream of the river, mg/l

Q_h——river flow, m³/s
