PLANT FOR BIOLOGICAL AEROBIC TREATMENT OF WASTE WATER

摘要

A plant for biological aerobic treatment of waste water combining in one tank hydraulically connected denitrification compartment with intake compartment, nitrification compartment and gravity separation compartment, horizontal pipe for supply of purified water from gravity separation compartment into the fixed beyond the tank filter for afterpurification of water at the level of the upper layer of the main filtering element. The end of the pipe is bent vertically down and submerged into water to the level lower the surface layer of water in compartment and comprises placed at the level of water discharge from the plant ultraviolet bactericidal lamp.
