MODULE FOR BIOLOGICAL WASTEWATER TREATMENT Russian patent published in 2018 - IPC C02F9/14 C02F3/04 C02F3/22 C02F1/74 

FIELD: water and air purification technology.

SUBSTANCE: invention relates to wastewater treatment systems and can be used to purify water from surfactants, organic contaminants, suspended solids and nitrogen compounds. In the method, the module for biological wastewater treatment includes housing 1, with first 2 and second settling chambers 3, located therein, bioreactor 4 with carrier material 41 for forming attached biocoenosis, system of water saturation with air oxygen – sprinkler 5, pipeline 6 for removal of purified water from the second chamber 3 and recirculated flow line 7 with circulation pump 8 immersed in second settling chamber 3. Housing 1 of the module is configured to be immersed in a sewage well to form chamber 10 after the installation, which is formed by the space between the walls of the well and housing 1 of the module, which serves for reception of wastewater and its equalization. In housing 1 of the module, opening 11 for overflowing into first settling chamber 2, located on the outside of housing 1, is formed.

EFFECT: invention makes it possible to provide the possibility of its installation in a sewage well with the maximum use of the volume of the sewage well, as well as the modernization of the existing treatment facilities, performed as a series of consecutively connected wells with overflows.
