基于响应面设计的海砂淡化参数优化
Optimization of sea sand desalination parameters using response surface methodology
摘要
Abstract
To investigate the optimal process parameters for sea sand desalination and their effects on chloride ion concentration,experimental design and analysis were conducted based on response surface methodology(RSM).The effects of stirring time,water-to-sand ratio,and temperature,together with their interactions,on the chloride ion concentration of desalinated sea sand were systematically examined.Based on the experimental results,a quadratic regression model with high predictive accuracy and high goodness of fit was established for chloride ion concentration.The results show that the significance of the three process parameters affecting chloride removal follows the order:water-to-sand ratio>water temperature>stirring time.A predictive equation for the chloride ion concentration of desalinated sea sand was developed,and the optimal process conditions were determined as washing time of 34.5 min,a water-to-sand ratio of 4.90,and a water temperature of 57.7℃.The engineering properties of sea sand treated under the optimal desalination conditions were subsequently evaluated,and the underlying mechanisms by which different sea sands affect the macroscopic performance were analyzed based on the test results.The proposed methodology provides an accurate and reliable approach for optimizing sea sand desalination parameters and offers useful guidance for the safe utilization and standardized production of sea sand.关键词
