Abstract: The present invention belongs to the sewage treatment and sand remediation technology, it is about a new type of system and method about sand/water remediation with photocatalytic fuel cell. The characteristic photocatalytic fuel cell (PFC) using photons or solar energy to produce highly active electron/holes is introduced into soil remediation system to degrade pollutants. In the constructed Visible light photocatalytic fuel cell sand water remediation system, there was overlying water above polluted sands in a tubular reactor. Allowing static adsorption equilibrium to buildup, in the built photocatalytic fuel cell, the photocatalytic anode and photoelectric catalytic cathode were connected by wires with an external resistance. Using 50 W halogen lamp as the light source, it maintains photocatalysis and electrocatalytic reactions to degrade pollutants in the system. By degrading the pollutants in the overlying water, the pollutants in the sand were also desorbed and degraded, and rapidly decreased to a very low level. Thus in this system water purification treatment and sand remediation take place simultaneously.
