Paper Title
Sulfure Removal from Urban Sewage in Bioelectrochemical Process

Abstract
Bio-electrochemical new technologies can, in wastewater treatment, convert the energy stored in the chemical bonds of biodegradable organic materials through the catalytic reaction of microorganisms into renewable electrical energy. The purpose of this study was to investigate the efficiency of a single-cavity bio-electrochemical system without catalyst as a simple and inexpensive method for removing corrosive and sedimentary sulfur compounds from urban sewage with indigenous bacteria. In this study, bacteria were isolated from urban sediment and sediments as Substrate was used. During the six months of the lead, the sulfate concentration reached at least 63 ± 57.2 mg / l, indicating the system's ability to remove 76.7% of sulphate from municipal wastewater and generate bioenergy. Maximum COD removal was 80% and maximum density was 54 W / cm3 and 82/1 W / cm2. The presence of elemental sulfur in sediments showed that these systems have the capability to optimize the recovery of elemental sulfur from urban sewage.
