Comprehensive Evaluation of Zero Discharge of Desulfurization Wastewater from Coal-fired Power Plants Based on Improved Particle Swarm Algorithm and Multi-objective Optimization Algorithm
The demand for zero discharge of desulfurization wastewater from coal-fired power plants is higher,and there are many objectives to be optimized,making it difficult to quantify the relevant indicators.Therefore,a comprehensive evaluation of zero discharge of desulfurization wastewater from coal-fired power plants based on improved particle swarm algorithm and multi-objective optimization is proposed.Based on the process flow of zero discharge technology for desulfurization wastewater in coal-fired power plants,indicators that affect the evaluation results are selected,and an evaluation indicator system is estab-lished.The evaluation indicators are quantified and overlaid using order changing function,Leonlief inverse matrix,and indica-tor function to obtain comprehensive evaluation indicators.A multi-objective optimization algorithm is introduced to construct an evaluation model with the goal of maximizing benefits,and an improved particle swarm algorithm is used to solve the diffu-sion problem.Based on this,a comprehensive evaluation value is obtained to achieve a comprehensive evaluation of zero dis-charge of desulfurization wastewater from coal-fired power plants.Taking the zero discharge process of desulfurization wastewater from actual coal-fired power plants as the research background,the evaluation performance of the proposed method is tested.The results show that the evaluation results obtained by the proposed method has a higher fitting coefficient and bet-ter evaluation effect.
