Abstract
The disclosure relates to a staggered electrode bio-electro-Fenton groundwater circulation well system, including a groundwater circulation well, a water pumping and injecting assembly and an in-well bio-electro-Fenton assembly. The water pumping and injecting assembly is configured to realize water pumping and injection between different screening sections of the groundwater circulation well. The bio-electro-Fenton assembly arranged in a first screening section of the groundwater circulation well includes at least one electrode device. A cathode and an anode of the electrode device form a spatially staggered arrangement according to different distribution areas. According to the disclosure, the spatially staggered arrangement of the cathode and the anode, the influence of oxygen on an anaerobic environment of an anode chamber in the electrode device is greatly reduced while ensuring the cathode takes oxygen as an electron acceptor, and the constructed bio-electro-Fenton system can accelerate the decomposition of organic pollutants in the groundwater circulation well.
