Abstract

the sewage networks functioning is accompanied by the processes of intensive emission of sewage gases (hydrogen sulfide, methane, ammonia, carbon dioxide) from the sewage stream into the air. Subsequent gas distribution due to the entraining stream ability results in gas accumulation in the under-roof space of pipelines and wells and subsequent seepage into the environment. This process reduces the functioning reliability and the environmental safety of the network and therefore requires preliminary forecasting during structures design and operation. The purpose of the study: to create an Ansys CFX based model of the sewage network. Results: creation of the sewage network model taking into account two-phase flow of wastewater stream and a mixture of air and sewage gas (hydrogen sulfide), model calculation data - liquid and gas phases ratio in the design area, the pressure field in the gas-air environment, the content of hydrogen sulfide volume fraction in the design area. Practical significance: determination of places of intensive emission of hydrogen sulfide and accumulation places to justify measures for gas cleaning and to protect the walls of pipes and structures against gas corrosion.
