Aeration system in the aeration tank for sewage treatment

摘要

Aeration system in the aeration tank for wastewater treatment, comprising over the corresponding area of ​​the bottom of the aeration tank arranged in at least two zones, one of which - nitrification, and another - denitrification, in which the nitrification zone located pneumatic aerators, which are assembled into respective modules and has in the bottom part of the corresponding portion of the bottom of the aeration tank, characterized in that at least each group of aerators formed of pneumatic aerators, diffusers wherein the group, located in zone nitrifi katsii, formed of a porous tube diffusers, which is used as aerators, each of which is configured as a tube formed of a glass cloth impregnated with the composition of thermosetting resins, with subsequent polymerization and having an ordered microporous structure with a predetermined distance between the pores, providing preventing coalescence onto air bubbles from the pores, and the group of aerators located in the denitrification zone is formed from a perforated tubular aerators, wherein within kazh Doi of said aerators are collected in groups aerating modules and arranged so as to form aeration in the aeration tank broad band.
