Process for the recovery of the environment in urban areas

摘要

Process of environmental recovery in urban regions, charaterised by the fact that it is formed by stages which start from the canalized domestic course (1) of water and sewer to be carried out in a micro process of removal of polluting material and/or substances (20), followed by, at least, one stage of aeration (11) of the canalized watercourse until it reaches the secondary watercourse (2), defined by a streamlet or totally urban secondary affluent; next, such secondary watercourse (2) is submitted to a medium process of removal of polluting materials and/or substances (20a), followed by at least one stage of aeration (11) of the secondary watercourse until it reaches the riverbed in its urban section (3), provided that such urban riverbed (3) is submitted to successive and intercalated stages of aeration (11) alongside its watercourse, with macro processes of removal of polluting materials and/or substances (20b), which extend along the urban sector (3) of the affluent watercourse before it reaches the receiving hydro body.
