Design and calculation solutions for designing biological treatment facilities on the pumping station example

The article is devoted to the study of design solutions for the biological treatment facility construction - a pumping station for emptying secondary sedimentation tanks. The main purpose of the design and construction of a pumping station for emptying is the use of advanced technology and the latest technological equipment for biological treatment of urban wastewater and sludge treatment. The pumping station for emptying secondary sedimentation tanks belongs to biological treatment facilities. Each sedimentation tank is provided for by an emptying pipeline, which enters the bottom of the sedimentation tank. The pumping station is a rectangular recessed structure where an emptying pump is installed. The initial data for design were considered and analysed: climatic conditions at the site, hydrogeological conditions, geological conditions, the assessing the impact of construction work on the surrounding buildings was analysed. The accepted volumetric planning and design solutions are described and substantiated. Recommendations for the building structures and foundations protection from destruction in aggressive gaseous and liquid environments are given. Compliance with the requirements of mechanical safety is justified by calculations performed manually, as well as use of a certified software package LIRA-SAPR. Technical solutions for the foundations were made on the basis of calculations performed in certified software complexes LIRA SAPR, the calculations of the enclosing structures were performed manually. Building structures calculations were carried out: lateral pressure, forces in the walls, reinforcement in the walls were determined, calculation of the structure for ascent was performed.
