SYSTEM FOR DISINFECTING SEWAGE PUMPING STATIONS AND WASTEWATER TREATMENT STATIONS Russian patent published in 2019 - IPC A61L2/20 C02F1/78 A61L2/24 A61L9/15 B01D53/34 

FIELD: sewerage.

SUBSTANCE: group of inventions can be used for disinfection of sewage pumping stations and wastewater treatment stations. Disinfection system comprises at least one ozone generator (5, 18) for generating ozone in a gaseous and/or liquid medium, at least one ozone detector (6, 7) for measuring ozone concentration in a gaseous medium, programmable timer (10), a human presence detector (14), central controller (13) for controlling ozone generators (5, 18) with taking into account the established level of ozone, at least one intermediate controller (11) for transmitting data to central controller (13), an airflow velocity detector (9) outputting from disinfected room (3), mounted inside the air outlet of the disinfected room. Central controller (13) is configured to stop ozone generators (5, 18) if the airflow velocity detector (9) detects that the air flow rate has dropped below the boundary value. Method of controlling ozone concentration includes controlling ozone generators at least in the environment of the disinfected room by central controller (13) in accordance with the obtained data of at least one ozone detector (6, 7) and the first and/or second ozone concentration level values, and/or the human presence detector (14) detector signal, and/or timer data (10), including data on time of day and/or time of year. Additionally, ozone generation is controlled by signal from airflow velocity detector (9).

EFFECT: group of inventions enables to eliminate unpleasant odor and causes thereof, to disinfect waste water, rooms and equipment by controlling ozone concentration, avoiding potentially dangerous effect of ozone on people working in disinfected environment or living near such environment.
