Review article

The article presents a substantiation of the problem of deterioration of sanitary and environmental conditions of the urban environment due to emissions of harmful gases from the sewerage network. The most dangerous gases are hydrogen sulfide and methane, which are products of biochemical reactions occurring during transportation through pipelines and facilities at the network. Based on the existing experimental data, estimation of gas emission intensity is presented, depending on the type of construction and flow conditions. In order to consider the places of intensification of gas emission, a method for simulation of the sewage network on the whole or its individual sections is proposed. There has been developed a conceptual model based on ANSYS CFX. In order to optimize the process of creating the calculation geometry, the authors used the Revit building information modeling software implementing the principle of BIM (Building Information Modeling).
