Present application and development of municipal wastewater treatment by high-rate anaerobic reactors

The anaerobic treatment of municipal wastewater becomes a focus with the development of anaerobic treatment technology,especially the appearance of high rate anaerobic reactors.In this paper,the research and application situations of upflow anaerobic sludge blanket(UASB) reactor in municipal wastewater treatment are described,and the application and development of municipal wastewater treatment by other high rate anaerobic reactors,such as anaerobic baffled reactor, internal circulation anaerobic reactor and expanded granular sludge bed reactor are also discussed.
