The invention discloses an intelligent detection and dynamic
early warning system based on
machine learning and multi-
source data fusion, which relates to the technical field of membrane
separation process monitoring and consists of a
data acquisition and preprocessing part, a
physical model and data driving model part, a dynamic weight fusion and self-adaptive mechanism part and a man-
machine interaction and alarm part. According to the
system, parameters such as
membrane flux,
transmembrane pressure difference, solution concentration, temperature, water
inlet flow and operation pressure are collected, an improved XGBoost
machine learning model is combined, and a comprehensive
pollution index is constructed to quantify the membrane
pollution degree; the model realizes double analysis of a
pollution mechanism and a data rule through
feature engineering. The
system supports full-closed-loop management from minute-level early warning to hour-level cleaning
decision making, the threshold value is dynamically adjusted through
Bayesian optimization, the generalization and anti-interference capacity of the
system are remarkably improved, and the system is suitable for intelligent operation and maintenance of membrane separation processes such as
reverse osmosis and
ultrafiltration.
