Fully considering the floor area in the plastic surgery hospital, the particularity of the waste liquid, the nearby operation of personnel, the equipment requirements occupy a small area, low noise, beautiful appearance, the treatment facility is a set of completely sealed equipment, the system operation is simple, the maintenance and management are convenient, the treatment system can run automatically, the regular operating cost is low, the investment is low, the sludge generation is small, and the treatment facility should have greater adaptability and emergency.
Design parameters
1. Nature of sewage: plastic surgery hospital waste liquid (can be selected according to the actual water quality).
2. Sewage volume: 200L D (daily treatment capacity can be customized according to user needs).
3. Inlet water quality: COD<1000mg L
4. Product size: 18 meters.
5. Effluent standard: The effluent quality of the treatment equipment meets the national "Comprehensive Sewage Discharge Standard" (GB8978-1996) ** discharge standard.
The sewage enters the grid canal of the sewage treatment station from the drainage system, and after removing the suspended particles and debris, it enters the regulating tank for homogenization and uniform adjustment, and then transmits the signal through the liquid level controller, and is pumped to the anoxic tank for hydrolysis and acidification, and the denitrification removes the total nitrogen and then flows into the aerobic tank for aerobic biochemical reaction. The adsorption is degraded, the effluent flows to the sedimentation tank, and the supernatant flows into the disinfection tank after the mud water is separated, and the disinfectant is added to contact the water body to kill the E. coli in the water, and then enters the clear water tank and discharges up to the standard.
