BIOCHEMICAL REACTOR FOR SEWAGE TREATMENT

摘要

A biochemical reactor designed to treat wastewater from minor sources of pollution using an activated sludge activation process in an upstream and / or growing microbial cultures, while all biochemical purification processes using an activation process proceed in a biochemical reactor containing one tank in which the functional zones of mechanical pre-treatment, aeration and separation of activated sludge are spatially separated from each other. The biological reactor includes a tank (1), in the central part of which a separation chamber (4) is placed, the area between the housing (5) of the separation chamber (4) and the housing (2) of the tank (1) is divided into two parts by two vertical separation walls A (7 ) and B (8), passing from the bottom (3) of the tank to the bottom of the outlet nozzle (29), namely, to the mechanical pre-cleaning chamber (11) and the aerated chamber (12). The active mixture is recirculated from the aerated chamber (12) with a high oxygen content into the mechanical pre-cleaning chamber (11) due to the fact that the mechanical pre-cleaning chamber (11) and the aerated chamber (12) are connected by openings (19, 22) located in the upper parts both vertical separation walls A (7) and B (8), while the aerating elements A (36) and B (37) located at the bottom of the aerated chamber (12) in front of the dividing walls A (7) and B (8) are located such that the height of the water column under aerating element A (36) is less than, h The height of the water column under the aerating element B (37) and / or the regulators (42, 43) of the air flow into the aerating elements A (36) and B (37) ensure the regulation of the air flow so that the amount of air supplied to the aerating element A (36)
