The invention relates to a multi-hole
foam glass carrier for a fast
mass transfer biological
fluidized bed and a preparation method and application thereof, which belong to
sewage disposal technology. The multi-hole
foam glass carrier is prepared by using waste glass as a
raw material to be composited with volcanic rocks,
coal ash,
coal gangue, furnace clinker,
iron powder, aluminum
powder, binding agents, foaming agents, foam stabilizer and fluxing agents by weight, and multi-hole
foam glass is obtained by stages of preheating, fast
sintering, foaming, fast cooling and annealing. The preparation process of the multi-hole foam glass carrier is simple in
route, easy to control and low in cost, and the prepared carrier is stable in performance, high in
porosity, large in specific surface area, resisting in
impact, good in mechanical performance, high in
biocompatibility, favorable to efficient fixing of the
microorganism, and suitable to the fast
mass transfer biological
fluidized bed. The multi-hole foam glass carrier solves the problem that biological immobilization carriers in the prior art are easy to abrade, small in bio-film formation amount, low in
mass transfer effects and the like in the fast
mass transfer biological
fluidized bed. The preparation method opens up new approaches for preparing the biological carriers, and fills blank spaces in using of foam glass materials in
sewage disposal.
