摘要
Apparatus and method for treatment of wastewater and odorous fumes therefrom with low mechanical complexity. The apparatus consists of 3 chambers (I, II, III) to which one air pump (7a) provides aeration of activated sludge and biofilm processes. The same pump (7a) acts to obtain sludge return from sedimentation zone (6) to a mixed bioreactor zone (4), acts to pump liquid up through the sedimentation zone to obtain a suspended sludge bed, and provides pumping action to obtain mixing of the bioreactor zone (4), and flushing of odorous gasses from the first treatment stage (I) to the final treatment stage (III) where the odours are adsorbed and removed by biological reactions. The treatment capacity of the final stage, a trickle filter (9), is enhanced by integrating at least one equalisation tank (8) within the filter mass of the trickle filter.
