<p>There is disclosed a one-unit fluidized-bed reactor for purification of waste water by means of biomass attached to carrier particles, comprising above the bottom of the reaction space a liquid distribution device (2), suited in particular for introduction of waste water in wide reactors achieving uniform fluidisation therein, consisting of a number of substantially horizontal pipes each of them having in the under-surface a number of regularly distributed openings for downward introduction of the liquid, and on top of the reaction space (1) united therewith a multifunctional separation compartment (3) for complete separation of the gas-liquid-solids mixture leaving the reactions space and for complete return of attached biomass into the reaction space. The separation compartment is construction-wise adaptable to treatments involving large or small gas fractions in reactors of varying width. The reactors are particularly suited for biological processes involving complete and firm attachment of biomass to carrier without undue surplus accretion of biomass.</p> |
