App Description

Complete mixed mode of river: calculation formula of pollutant concentration

$$ c=(c _pQ _p+c _hQ _h)/(Q _p+Q _h) $$

• c---concentration of pollutants after complete mixing of wastewater and river water, mg/L;   * c_p---concentration of pollutants in sewage, mg/L;   * Q_p---sewage flow, m³/s;   * c_p---the water concentration of the upstream water, mg/L;   * Q_p---the flow of water from the upstream of the sewage outlet, m³/s;

Applicable conditions:

* Calculation of pollutant concentration after rapid and complete mixing of wastewater and river water;   * Contaminants are persistent pollutants, and the concentration of pollutants after the wastewater and   * river water are completely mixed for a certain period of time (distance).   * The river is a constant flow:   * Continuous and stable discharge of wastewater.

Usage example

Input data:

Cp - pollutant discharge concentration: 3

Ch—concentration of pollutants in the upper reaches of the river: 4

Qp - Wastewater discharge: 3
