Abstract

The invention discloses a catalyst screening method. The method comprises the following steps: determining a plurality of pollution evaluation indexes in a water body to be treated; performing test treatment to obtain the change rate of each pollution evaluation index in the plurality of pollution evaluation indexes after the test treatment is performed on the water body to be treated by each of the plurality of alternative catalysts; screening out a plurality of catalysts and a plurality of correlation pollution evaluation indexes; solving the total change rate of the correlation pollution evaluation indexes of each catalyst; selecting the catalyst with the maximum total change rate; according to the method, the screening accuracy of the catalyst can be improved, and the catalytic effect of the screened catalyst is better.
