Introducing the emission process of hydrogen sulfide to a sewer process model (WATS)

摘要: Emission of hydrogen sulfide in sewer networks results odor, health and corrosion problems. These problems generally occur when wastewater is transported under anaerobic turbulent conditions. Studies on integrated aerobic/anaerobic processes sewers have led to a conceptual process model, WATS (Wastewater Aerobic/anaerobic Transformations Sewers). The model accounts for the carbon cycle, reaeration formation. However, handle more efficiently, other aspects sulfur cycle need be included. Emphasis this study an extension terms emission. A fundamental concept extended related emission molecular form thereby pH wastewater. An engineering application includes different scenarios performance concerning dissolved oxygen-limited By applying users can realistically cope with fate sulfide. Consequently, dealing no longer restricted formation but also take transfer across air-water interface into account.
