Abstract

The invention discloses a double-carrier fixed bed biomembrane reactor which comprises a biomembrane carrier and a carrier, wherein the outer surface of the carrier is coated with antibacterial nanoparticles. According to the double-carrier fixed bed biomembrane reactor, the problems that the traditional fixed bed biomembrane reactor needs operations of periodically backwash and cleaning the carrier, replacing an aerator and the like can be overcome.

Description

technical field [0001] The invention relates to a fixed-bed biofilm reactor, in particular to a double-carrier fixed-bed biofilm reactor with a biofilm carrier and an antibacterial carrier. Background technique [0002] The treatment of difficult industrial wastewater poses a great challenge to the environmental protection industry. Generally speaking, industrial wastewater has the following characteristics: 1) The industry differences are very large; 2) The COD value is high, often exceeding 10,000; 3) The composition is very different. Complex, some molecules are difficult to degrade and highly toxic; 4) Some wastewater contains very high salinity, with a concentration of 50g / L or even higher; 5) The impact load is very large and can reach the peak in a short time. [0003] At the same time, the biochemical removal of nitrogen-containing substances in industrial wastewater is also very important, because excessive nitrogen content is one of the important causes of eutrophi...
