TREATMENT FOR DOMESTIC AND INDUSTRIAL WASTE WATER

摘要

The present invention refers to a method and system for the treatment of wastewater from domestic and industrial sources that effectively remove the water pollutants, thus reducing the generation of organic residues. The method comprises the stages of: providing wastewater in a wastewater collector (1); conveying at least a portion of said wastewater to a separating unit of coarse solids (2); making said portion of water to undergo filtering in said unit; collecting at least part of the water from the stage (iii), preferably through gravity medium in a first conveying plant (3); conveying at least a portion of the water from the stage (iv) to the separating unit of fine solids (4); making said portion of water to undergo filtering in said unit; collecting at least part of the water from the stage (vi) in a second conveying plant (5); conveying at least a portion of the water from the second conveying plant (5) to the biologic treatment unit (6) through pumping mediums and distribute the water to be treated preferably in homogenous way over said biologic treatment unit (6); making said portion of water to undergo the biologic treatment unit (6); collecting the water treated at the bottom of the biologic treatment unit (6) and optionally convey it to a chemical disinfection unit (8); making said portion of water to undergo treatment in said chemical disinfection unit; and optionally collecting the water treated in the stage (xi) in a container.

1. A method of treatment of wastewater from domestic and industrial sources that effectively remove the water pollutants, thus reducing the generation of organic residues and keeping continuous operation, WHEREIN it comprises the stages of:
i. providing wastewater in a wastewater collector (1); ii. conveying at least a portion of said wastewater to a separating unit of coarse solids (2) or coarse filtering station; iii. making said portion of water to undergo filtering in said separating unit of coarse solids; iv. collecting at least part of the water from the stage preferably through gravity medium in a first conveying plant (3); and v. conveying at least a portion of the water from the stage (iv) to the separating unit of fine solids (4) or fine filtering station; vi. making said portion of water to undergo filtering in said separating unit of fine solids; vii. collecting at least part of the water from the stage (vi), preferably through gravity medium in a second conveying plant (5); viii. conveying at least a portion of the water from the second conveying plant (5) to a biologic treatment unit (6), preferably through pumping medium and distribute the water to be treated preferably in homogenous way over said biologic treatment unit (6); ix. making said portion of water to undergo treatment in the biologic treatment unit (6); x. collecting the water treated at the bottom of the biologic treatment unit (6) and convey it to a chemical disinfection unit (8) through gravity medium; xi. making said portion of water to undergo treatment in said chemical disinfection unit; and xii. optionally collecting the water treated in the stage (xi) in a container.
