摘要

In order to solve the high energy consumption and other problems of the post-pump filter, an efficient pre-pump filter, pontoon mesh rotary filter, has been developed. In this study, the physical full test under the factors of flow rate, sand content, flushing flow rate, and filtration time was carried out using filtration efficiency as an index. The results were analyzed using quantile analysis, PPR, MLP, and Sobol index, and a prediction model was established, in which the MLP-based prediction model was more effective. The influence ranking of single and double factors were determined and the optimum working conditions were proposed. The results of the study provide a reference for filters, enrich the theory of micro-pressure filtration, and provide operational parameters for filter applications.
