Abstract

Aiming at the problem of the traditional flue gas desulfurization and effluent disposal, two identical dual-chambered Microbial fuel cells (MFCs) are designed to remove man-made flue gas pre-treatment wastewater (FGPW). Glucose is used as the carbon source of the Sulfate reducing bacteria (SRB). Carbon cloth is used as the material of anodic and cathode. The treatment performance of flue gas pre-treatment wastewater and the possibility of electricity harvesting and sulfur recovery were investigated. The results show that the output voltage is 0.68-0.72V and the maximum current density is 28.12mA/m² at pH=7.520. The concentration of sulfate measured with ion chromatography is decreased gradually during the operation of MFC. The elemental sulfur is found in carbon cloth (taken from the MFC after working for 58 days) by analysis with XPS. The results suggest that treatment of flue gas pre-treatment wastewater and electricity harvesting and sulfur recovery by MFC is technical feasibility.
