3. WASTE WATER TREATMENT TECHNOLOGY OF THE WEDDING RESTAURANTmicroorganisms
Technology explanation Wastewater generated from many locations and locations through septic tanks, grease separating tanks will be collected and led to the centralized wastewater treatment system of the restaurant. Air tanks Conditioning tanks are used to stabilize the flow and concentration of wastewater inlet, helping to stabilize the biological treatment facilities in the back. From the regulating tank, wastewater is pumped to the SBR biological tank in batches.
SBR biological tank SBR tanks will perform the processes of carbon reduction, nitrification, denitrification and biochemical phosphor reduction because aerobic, anaerobic and anaerobic processes in the tank can be adjusted by providing oxygen.
Pressure filter tank Water after being deposited in SBR tank will be transferred to an intermediate tank, from here pumped to a pressure filter tank to remove the residue remaining in the wastewater.
After passing the filter tank, wastewater is transferred to a disinfection tank.
Disinfection tank In the disinfection tank, wastewater is mixed with Chlorine or Javen solution according to a certain concentration to remove Coliform bacteria component in the wastewater before being discharged into the environment.
Water after disinfection, meeting QCVN 14: 2008 / BTNMT standard, column A and is eligible for discharge to the receiving source. Sludge storage tank The amount of excess sludge daily is pumped to the sludge tank, periodically hiring a car to suck and discharge according to regulations.
