Overflow pollutant control evaluation method based on equivalence principle

The invention discloses an overflow pollutant management and control evaluation method based on an equivalence principle. The method comprises the steps of taking the total control of overflow pollutants as a management and control index, and determining the concentration of an overflow pollutant management and control target according to the equivalence principle, i.e., the principle that a combined system effect is not lower than a split system effect. The method is based on an equivalence principle, the overflow pollutant management and control total amount and the management and control target are scientifically determined; the most reasonable overflow pollutant management and control evaluation index under the existing execution standard and the actual condition is provided; accordingto the method, the cause of complex overflow does not need to be considered, the overflow water amount, the concentration of one pollutant in overflow and the concentration of ammonia nitrogen in overflow can be obtained onl
