| titleOfInvention | Method for preparing porous polyurethane spherical spheres and their use in wastewater treatment |
| abstract | Foamed polyurethane microspheres for the immobilization of microorganisms were polymerized, and the density was generally lower when water and benzene, water and cyclohexane were used as solvents. Such a carrier had excellent foaming power and a large amount after polymerization, and spherical density increased with addition of activated carbon and zeolite during polymerization.n n n In order to evaluate the performance of the foamed polyurethane microspheres as carriers, comparative experiments were conducted with the sintered porous glass spheres. WA, WCA, and GB showed 79%, 87%, and 88% COD removal after 24 hours in primary culture, but 94%, 99%, and 98% removal after 10 hours in 10 culture. . |
