FIELD: mechanics.
SUBSTANCE: invention relates to aeration devices of minor purification installations used in separate small houses, cottages and country houses. The device contains capacity 1, biological loading, a sewage feed branch pipe, an air feed system including compressor 2 with distribution valve 3, small-bubble aerator 10 consisting of horizontal pipe 12 with a micro-punched elastic cover and a feed pipeline connected to the air feed system. Every biological loading is made in the form of section 4 and consists of, at least, two vertically arranged frames 5 with flexible spear-like structural elements 6 interconnected by racks 7. Every top frame 5 is furnished with floats 8 arranged at its top part and connected with cross-beams 9, while small-bubble aerators 10 are fixed on the bottom frames 5 and attached to the lower part of each biological loading 4 by racks 7. Every small-bubble aerator 10 is furnished with a cylindrical sinker located coaxially inside a horizontal pipe filled with a material with density considerably exceeding that of a liquid in the aforesaid capacity. Small-bubble aerators 10 are connected by means of air ducts 11 with distribution valve 3 and compressor 2.
EFFECT: higher efficiency of sewage purification and simpler design.
