Method for simultaneously optimizing COD and ammonia nitrogen removal effects of reverse osmosis membranes on biogas slurry

The invention provides a method for simultaneously optimizing the COD and ammonia nitrogen removal effects of reverse osmosis membranes on biogas slurry. According to the method, a response surface optimization method is integrated with multi-objective genetic algorithm optimization, and accordingly, the comprehensive optimization of COD and ammonia nitrogen of the biogas slurry by the reverse osmosis membranes is realized; the response surface design method is improved, and thus a cumbersome pre-experimental process is omitted. Compared with conventional response surface optimization methods,the optimization method has the advantages that the fitting mode and the response surface drawing mode can be selected more fittingly, the defect that the conventional response surface optimization methods can only optimize single target functions is overcome, multi-objective optimization is realized, the whole optimization process is more flexible and free, and accordingly, the method has high practicability and extensi
