- Abstract:
- The terrain elevation difference of a waterworks in Guizhou Province is large. If the buildings or structures are arranged according to the conventional layout, surrounding residences need to be relocated, and the slope support treatment is difficult and risky. Therefore, the design abandoned the traditional layout, and utilized the vertical space for superimposed distribution of the treatment structures and dosing rooms, respectively. That was, clean-water tank was located under mechanical mixing flocculation tank, inclined tube sedimentation tank and V?type filter, and polyaluminum chloride dosing room, potassium permanganate dosing room and sodium hypochlorite preparation room and dosing room were combined constructed in a two?story building. The overall design requirements of the superimposed tank, the superimposed layout, the main technological design parameters of each single unit and the passage relationship, the vertical transportation, ventilation and maintenance measures were introduced. The superimposed design not only met the requirements of technological process, but also met the engineering requirements, and achieved good engineering benefits.
