How should sewage generated by the Animal Disease Control and Prevention Center be treated?

The wastewater discharged from the Animal Disease Control and Prevention Center contains a large number of bacteria, viruses, parasite eggs, pet feces, and toxic and hazardous substances, some of which may contain radioactivity. Therefore, wastewater from the Animal CDC should be treated and discharged by a unified wastewater treatment system.

The wastewater treatment process of the Animal Disease Control Center adopts the biological treatment method of Aike wastewater: biological contact oxidation + sedimentation + disinfection process, i.e., A/O process. The equipment covers a small area, the process is simple to operate, the one-time investment and operating costs are low, and the water treatment effect is good. The ammonia nitrogen in the sewage is transformed into nitrite nitrogen and nitrate nitrogen, and then nitrate nitrogen is transformed into nitrogen through the action of denitrifying bacteria to remove the nitrogen in the sewage. The key is to pay attention to the sterilization and disinfection of sewage and sludge. The key is to kill pathogenic bacteria.
