According to the principle of microbial fuel cells, electrochemically active electrogenic microorganisms (electrogenic bacteria) are used as anode catalysts to oxidize and decompose organic matter in the water. The generated electrons are transferred along the electrode to generate current, which directly converts chemical energy into electrical energy.

When toxic substances flow in, the activity of electrogenic bacteria decreases, resulting in a decrease in current; when nutrient organic matter flows in, the activity of electrogenic bacteria increases, resulting in an increase in current.
