| titleOfInvention | A/A/O and MAP combined treatment method for kitchen wastewater |
| abstract | Provided is an A/A/O and MAP combined treatment method for kitchen wastewater, comprising the following steps: (1) adjusting the pH of wastewater to pH=6.8-7.5; (2) making the wastewater after pH adjustment enter A/A /O system, A/A/O system includes anaerobic fermentation tank, anoxic tank, aerobic tank and secondary sedimentation tank, so that the wastewater enters the anaerobic fermentation tank, anoxic tank, aerobic tank and secondary sedimentation tank in turn; ( 3) Make the sediment of the anaerobic fermentation tank and the sludge in step (2) enter the MAP system, the MAP system includes the MAP reaction tank and the MPA sedimentation tank, add magnesium salt and phosphate into the MAP reaction tank, and control the temperature to 20– 30°C, react for 15-20min; (4) add flocculant to the MAP reaction tank, and react at 20-30°C for 15-20min; (5) make the product processed in step (4) enter the MAP sedimentation tank , let stand until the supernatant and the precipitate are clearly separated. The invention optimizes and combines modern traditional wastewater treatment processes, effectively improves the removal efficiency of ammonia nitrogen, COD, BOD and total phosphorus in wastewater, so that wastewater can be better purified. |
