Application progress of inorganic sulfur autotrophic denitrification treatment of sewage wastewater
The microbial characteristics of sulfur autotrophic denitrification system was systematically ex-pounded.The advantages of sulfur autotrophic denitrifying microorganisms in different reactors and the functional enzymes of inorganic sulfur source redox were analyzed.The methods of accelerating sulfur au-totrophic denitrification were introduced,such as reducing the particle size of S0 particles,applied magnet-ic field,adding sulfur metabolism intermediates or cattle serum protein.The practical engineering applica-tion of sulfur autotrophic denitrification at home and abroad was mainly summarized.The future develop-ment direction of sulfur autotrophic denitrification technology was prospected.It was aimed to provide ref-erence for the development of sulfur autotrophic denitrification system.
