摘要

The fluidised-bed reactor for biological waste water purification using carrier particles for microorganisms is composed of a tank (1) equipped with a retaining system (12, 15, 17), aeration units (3) for the carrier particles and a jet pump (4) arranged longitudinally along the tank (1) for recycling the particles. The waste water stream (19) to be purified is ejected from the propellant nozzle (5) of the jet pump (4). ……
