Sewage treatment tower design
Abstract：Tower is an important production equipment in chemical, petroleum and other industries widely used. After long-term development, the formation of a variety of types of structures to meet the needs of all parties. Device for the realization of the distillation column and the operation of the absorption are called two separate distillation column and the absorber. In recent years, with the central and local governments on industrial production and attaches great importance to environmental protection, construction of industrial sewage treatment works at an unprecedented pace, policy makers, engineers, technicians and management personnel to run an aspect of common concern is how to enhance and guarantee functions, efficiency and management of these projects and facilities, so creating their own sewage treatment system, the sewage treatment process run by the optimal solution, it is particularly important. Conducted in accordance with the mission statement tower design, structural design process itself, select the relevant standard.
