摘要

The textile dyeing industry produces large volumes of wastewater during dyeing processes where the major step includes the color removal and COD removal. In the present study, the combined electrooxidation process and a novel biological degradation at high compressed gas pressure were studied. The removal of color in the real textile dye effluent was achieved by electrooxidation with Titanium Substrate Insoluble anode and titanium as cathode through generation of hypochlorite. The hypochlorite produced during the electrooxidation was removed by exposing the solution to direct sunlight. The impact of compressed atmospheric condition on the degradation of organics by Pseudomonas aeruginosa (MTCC No.1201, GenBank Acc. No KC545414) was studied. The compressed gas pressure condition increases the level of dissolved gas in the liquid phase and exerts the pressure on the growing cells in the liquid phase. Interesting synchronization between the utilization of oxygen by active microbial cells and the dissolution of oxygen in the water from gas phase was observed which enhanced the bacterial degradation process. It should be mentioned here that the P. aeruginosa was grown without addition of nutrients. The compressed atmospheric pressure enhances the bacterial proliferation, EPS production and COD reduction in the electrooxidized effluent. FTIR and HPLC reveal the degradation of organics in the compressed pressure condition.
