A case study on the biological start-up of hydrolysis acidification in a sewage treatment plant of a certain industrial park in Feicheng City
(1) Company Profile: State-owned enterprise Water Group
(2) Wastewater type: Tail water treatment of enterprises in industrial parks
(3) Wastewater treatment capacity: 10,000 cubic meters per day
(4) Treatment process: Hydrolysis acidification + two-stage AO tank + secondary sedimentation tank + high-efficiency sedimentation + high-efficiency filter + first-stage ozone oxidation + first-stage biological carbon filter + second-stage ozone oxidation + second-stage biological filter + disinfection tank
(1) By adding the Qinggang ® series of highly efficient strains, it features dual high-efficiency characteristics: short acclimation time, strong ability to remove pollutants, and rapid cultivation of bacterial colonies.
Serial number | Strain name | Specification | Dosage |
1 | Qinggang®Hydrolytic Acidifying Bacteria | 2 billion CFU/g | 500kg |
2 | Qinggang®Anaerobic Removal Bacteria | 10 kilograms per bag | 300kg |
3 | Qinggang® COD Removal Bacteria (Aerobic) | 200 billion cfu/g | 100kg |
4 | Qinggang Ammonia-Nitrogen Removal Bacteria (Autotrophic) | 500mgNH3-N/L/h | 100kg |
Add our company's hydrolysis acidification bacteria and anaerobic biological growth promozers to rapidly cultivate the activated sludge in the hydrolysis acidification process, thereby enhancing the biodegradability of the wastewater. COD removal bacteria and ammonia nitrogen removal bacteria (autotrophic) are added to the aerobic tank to rapidly establish an aerobic microbial community and enhance the system's capacity to remove COD and ammonia nitrogen. Subsequently, the gradient inflow method was adopted to gradually increase the treatment load of the system. After 15 days of commissioning, the hydrolysis acidification process was successfully initiated.
