PROCESS FOR THE BIOLOGICAL TREATMENT OF WASTE WATER ON AN ADSORPTION BED

摘要

A process for treating a liquid effluent, such as waste water, containing biodegradable organic materials in solution and/or in suspension which consists in causing this effluent to flow over an adsorbing material previously seeded with microbian flora and on which said organic materials spread out depending on their ease of adsorption while thus defining successive layers. This process is characterized in that the adsorbing material is in the form of as many independent beds as there are layers, these beds being disposed in series.
