Abstract
The Sequencing Batch Reactors (SBR) is a variation of activated sludge and has been wide applied in wastewater treatment since 1920s. The advantages of this technology are not only the high performance in low or varying flow patterns but also present worth cost for a long time. Therefore, the article evaluates the technical -economic efficiency of this technology in municipal wastewater treatment from combined sewerage system. Based on building and operation pilot SBR with process Nitrification/Denitrification and bio-film in municipal wastewater treatment plan for 1 months, the technical -economic efficiency has been determinates. Firstly, the efficiency removal pollutants is more stable and the quality of pilot’s effluence achieved Russian Standard about treated water. After that, the environmental damage has been decreased for 8 – 11 time, especially damage from nitrogen ammonia and nitrate. At least, the calculation from economic factors of SBR has been showed that the cost of treating 1 m3 wastewater than 0.5 USD when optimized this technology by process Nitrification/Denitrification and bio-film.
