Reduction of environmental hazard of hudrogen sulfide emission from sewerage pipelines and visual pollution, formed by degassing units
At some sites of the sewage collector in Kharkov concentration of hydrogen sulfide in the underroof space exceeds in thousands of times daily average MPC. As a result the gaseous emissions from the sewage network in the city atmosphere the content of hydrogen sulfide in the atmosphere of residential development area may exceed the MPCd.a. The degasifier, installed above the sewage shaft efficiently rectifies gas releases. Design solutions are developed, which allow to harmonize degasifiers on sewerage nets with urban environment of different application.
