AI Technical Summary

Technical Problem

Existing anaerobic digester simulation and control technologies cannot effectively simulate the spatial heterogeneity inside the reactor, resulting in delayed fault detection, large computational load, and an inability to meet the real-time online prediction and rapid control requirements of industrial sites.

Method used

A simulation system based on discrete spatiotemporal multi-agent evolution is adopted. Through physical parameter mapping, discrete spatiotemporal calculation, virtual microbial community construction and dynamic evolution coupling processing, the microbial ecology and mass transfer process inside the reactor are simulated in detail, so as to realize early warning of failure and process optimization.

Benefits of technology

It enables low-cost real-time fault early warning and process optimization, improves fault prediction accuracy, reduces computational complexity, provides a model of micro-macro cross-scale instability mechanism, and provides a theoretical basis for formulating early intervention strategies.
