Based on IF-PSO River Basin Water Pollutant Total Amount Control Optimization Model

This research based on the total amount control of river basin water pollution reducing, and with YiTong river basin as the study case, to obtain the optimal decision scheme of water environmental pollution control, acquired in 2015 the smallest reduction of COD and ammonia nitrogen is 77804.53 tons and 6644.92 tons, in 2020 obtained the smallest reduction of COD and ammonia nitrogen is 33518.49 tons and 2887.69 tons; acquired in 2020 the smallest reduction of COD and ammonia nitrogen is 77103.39 tons and 6584.52 tons, in 2010 obtained the smallest reduction of COD and ammonia nitrogen is 34219.62 tons and 2948.09 tons, provided decision-making support for the basin water pollution control, improve watershed management and control of water pollutants.
