摘要
A process for the environmental recovery of water beds in urban areas that uses a water treatment process or a process of removal of contaminant materials and / or substances consisting of the following steps: application of flocculating or coagulating material (21) a a volume of water (1, 2 or 3) to be treated; promotion of flocculation (22) of the volume of water (1, 2 or 3), ensuring the aggregation of suspended particles (12), defining particles of larger dimensions; subjecting those coagulating particles of greater size (12) to downstream of the volume of water (1, 2 or 3) to successive stages of dissolution and injection of air (11), causing the flotation of such aggregate particles (12); allow the formation of a dissolved air flotation basin (24) downstream (25), with the agglomeration of the floating material (13) on the surface and near the margins of the water volume (1, 2 or 3), defining the concentration of floating material (13) in a restricted area (23) of the surface of the watercourse (1, 2 or 3) and promoting the removal (26) of that floating material (13) retained in that restricted area ( 25) of the surface of the water volume (1, 2 or 3); characterizing the process of environmental recovery by understanding the successive realization of these steps along the escape of sewage and sewage, from the domestic runoff pipe (1) of water and sewage, in which a process of material removal begins and / or polluting substances (20); followed by at least one stage of aeration (11) of water flowing through the pipe until the waters reach the secondary exhaust (2), defined by a totally urban secondary canyon or tributary; Subsequently, said secondary leakage (2) is subjected to an average process of removal of contaminant materials and / or substances (20a), followed, at least, by an aeration stage (11) of the secondary water leakage, until arrive at the river bed in its urban section (3), then submitting said urban river bed (3), along its escape, to successive and interspersed aeration stages (11) using material removal macroprocesses and / or polluting substances (20b), extending along the urban section (3) of the tributary escape, before the latter reaches the receiving water body.
