Construction drawing of radial flow secondary sedimentation tank of sewage plant (including plan and section)

This drawing is the process construction drawing (including civil engineering) of a slaughterhouse sewage plant, which includes: system installation drawing, process flow elevation diagram, equipment layout and control instructions, regulation pool accident pool, contact oxidation pool plan, etc. The contents are detailed and can be used for reference.

Content introduction 1. All dimensions marked in the drawing are in mm except elevation in meters; 2. Except for the water pump, valve and expansion joint, which are connected by flange, the steel pipe is welded 3. Handrails shall be set on the walkway plates, and the pipe trench shall be covered with grating plates after the installation of air pipes; This drawing: water decanter, submerged mixer, submersible sewage pump and other major equipment Cass scale sewage pipe plan Sewage plant plan Coarse grid lifting pump room plan

This project is the chlorination room of sewage sludge treatment project of a river pollution comprehensive treatment project in Xianning City. Single storey reinforced concrete frame structure. The total building area is 234M2, and the building base area is 244.5M2. The seismic fortification intensity of the building is 6 degrees, and the fire resistance rating of the building is Grade II; The fire hazard is classified as Class B. The reasonable service life of the building is 50 years. The design elevation of the project is ± 0.000m, which is equivalent to the elevation of the Yellow Sea of 25.30m. The height difference between indoor and outdoor is 0.300m. The roof waterproof grade of this project is Grade II. Environmental category of building concrete structure: Class I above the design ground, Class II a below the design ground. Crack control grade: Grade III. Basic wind pressure: Wo=0.35kN/m ￠, ground roughness: Class B. Standard value of design load: dead load: roof waterproof and thermal insulation layer 3.05KN/m ￠; The volume weight of roof slope making material is ≤ 6.0KN/m, and the use live load: no access roof: 0.5KN/m ￠ sewage treatment scale: 60000 m3/d in the short term, and 60000 m3/d in the long term. The chlorination room is used for chlorination of secondary treated water. The civil engineering is designed as 120000 m3/d in the long term, and the equipment is installed as 60000 m3/d. Chlorine dosing room includes chlorine storage room, vacuum chlorinator room and chlorine absorption unit room. The chlorine dosage for disinfection of secondary treated water is designed as 5~12mg/L. The chlorine bottle reserve in the chlorine storage room is set with 12 chlorine bottles, 8 online, divided into two bus bars, and each row is set with 5 bottle positions.

Design description: none, type: sewage treatment plant, process selection: others, design stage: construction drawing design, Number of sheets: Less than 10 sheets

The plan of the sewage treatment plant, including the reasonable layout of sedimentation tank, flocculation tank, concentration tank and dosing room, is intuitive to the overall layout of the sewage treatment plant.
