| Abstract: | Simultaneous aerobic treatment of COD, phosphate, nitrate and H2S in a synthetic sewage wastewater was carried out using porous ceramic immobilized photosynthetic bacteria, Rhodobacter sphaeroidesS, Rb. sphaeroidesNR-3 and Rhodopseudomonas palustris. In the batch treatment, effective simultaneous removal of COD (89%), phosphate (77%), nitrate (99%) and H2S (99.8%) was observed after 48 h. In semi-continuous treatments with dilution rates of 0.17 to 0.75 day–1under aerobic conditions, simultaneous removal of these four components was also observed after about one month. |
