1. Scope of application and principle:
MBBR was developed and applied in the mid-1990s. It has the advantages of both traditional fluidized bed and biological contact oxidation, and is a new and efficient sewage
treatment method. So far, MBBR has been used in small-scale, pilot and production experiments for domestic sewage treatment and industrial wastewater treatment abroad , and good results have been achieved.
Among them, the Captor process in the United States and the Linpor process in Germany are currently two relatively mature porous suspended carrier systems. Polyurethane foam blocks are added to the complete mixing reactor for microbial attachment and growth, which
is used to treat urban domestic sewage. Its removal and nitrification of BOD are studied.
The results show that nitrifying bacteria preferentially attach and grow on the carrier, and the nitrification activity reaches 0.33mgN/h•carrier block (carrier volume is 8cm3/block). Within 4h, BOD can be completely removed, and nitrification occurs subsequently, and nitrification can be completed within 10h. In the past 10 years, moving bed biofilm technology has been developed in Norway. Now there are more than 100 sewage treatment plants based on this technology in operation or under construction in 17 countries. They are m*nly used to remove organic matter and ammonia nitrogen from municipal sewage or industrial wastewater.
