Problems solved by technology

In the 1980s, microbial fuel cells were proven to be applicable to daily production and living processes, but microbial fuel cells are difficult to completely oxidize organic pollutants, and microbial fuel cells lack long-term stability due to the influence of the life cycle of microorganisms themselves.

Abstract

The invention provides two TiO2-based photocatalytic composite-electrode fuel cells with different structures, and an apparatus used for processing organic wastewater. The apparatus comprises a speed regulator, a driving motor, a photocathode shaft, a photocathode rotary table, plural sheets of photo-anodes, a fuel cell reaction tank, and an excitation light source. The apparatus is characterized in that: a draft-tube is arranged on the bottom of the fuel cell reaction tank; and a water pump is arranged on the draft-tube. The water pump is started; the organic wastewater is transferred from the draft-tube on the bottom of the photo-anode reaction tank to the top of the photo-anodes, and flows down, such that a liquid film is formed on the surfaces of the photo-anodes; meanwhile, the driving motor is started, the rotation speed of the photocathode rotary table is controlled by the speed regulator, such that the photocathode rotary table rotates, and a liquid film is also formed on the surface of the photocathode. Photo-anodes with different structures are adopted, such that the processing efficiency of the organic wastewater is improved. The photo-anodes are designed as rectangles, such that the liquid film formed by the water flow on the surfaces of the photo-anodes is more uniform, and the organic wastewater can be more effectively processed by using the TiO2-based photocatalytic composite-electrode fuel cell.
