| Abstract: | When a flood occurs,a large amount of flood water will carry sewage and various types of garbage,resulting in increased pollutants in the water body and serious damage to the ecological environment.Based on this,the control of pollutant migration and transformation in regional water environment after flood disaster is proposed.First,to analyze the adsorption mechanism of pollutants,establish adsorption kinetic equations and isotherm models,determine the speed of pollutants in the removal of volatiles,and calculate the degree of volatile losses;second,comprehensively explore through convection,molecular diffusion,radioactive decay,etc.The basic laws of pollutant migration and transformation,obtaining migration and transformation equations,and constructing mathematical models;taking Sanya as an example,using migration model to control scheme generation and combination,scheme selection and optimization,determine the best control method,and use the Granger multiplier rule Calculate the control rate of pollutants.The actual results show that the designed scheme combined with multi-objective combination optimization makes the control scheme more in line with the actual situation,thereby minimizing the pollution of the water body environment by flood disasters. |
