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. The current signal passes through The load amplifies the voltage signal and converts the voltage signal into a visible toxicity value through a calculation formula. 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. The inflow of toxic substances or nutrient-type organic matter is judged by the sharp decrease and increase of current (voltage), and real-time monitoring and analysis of toxic substances and loaded organic matter in water bodies can be realized.
