A water quality monitoring device based on a microbial fuel cell, relating to the technical field of water quality monitoring. A storage battery module is provided in a main machine body (4) to provide power. The main machine body (4) can move in a water environment to detect the water quality of different areas in the water environment. An integrated sensor module (3) and a microbial fuel cell module are provided on the main machine body (4). The integrated sensor module (3) collects a pH value in the water environment. The microbial fuel cell module continuously and stably charges the storage battery module by means of sliding mode control, and collects data of current that is generated in the water environment and changes with time, wherein the data of the current changing with time is used for determining a heavy metal pollution status of the water environment. The water quality monitoring device combines a microbial fuel cell with a water quality monitoring system, improves the quality of water resources, and can also provide stable power supply for a long time to realize long-term real-time monitoring of water quality. The device has large technology and market development space, and has remarkable social benefits, economic benefits and environmental benefits.
