PROCESSO DE PURIFICACAO, POR VIA BIOLOGIGA, DE AGUAS RESIDUAIS SOBRE LEITO DE MATERIAL GRANULAR |
摘要 |
<p>Water is purified according to the principle of a biomass fixed on an aerated granular bed acting as a filter in a biological reactor. The water to be purified is sent, without presettling, upwardly through a multilayer granular bed placed in the reactor. The injection point of oxygenated gas determines two succesive zones, anaerobic and then aerobic. The water is evacuated from the reactor at the top thereof, or at a certain level of the bed. A sudden downward flushing of the filter with water is provided to eliminate the biomass. The filter is periodically washed with air/water and then rinsed with water.</p> |
