Embodiment 1
[0032] The technological process of this denitrification and dephosphorization A-MA-A method is as follows figure 1 shown.
[0033] The process is mainly composed of anaerobic tank 1, rapid sedimentation tank 2, micro-aerobic tank 3, anoxic tank 4, and secondary sedimentation tank 5. At the same time, COD is also degraded, and anaerobic ammonium oxidation dominant bacteria are cultivated in the pool, ammonia nitrogen oxidation is carried out in the micro-aerobic pool, and environmental conditions are controlled to enrich nitrite, and ammonia oxidizing bacteria (AOB) are cultivated in the pool as the dominant bacterial group .
[0034] The pH meter, DO meter and ORP meter in the main biological reaction tank are automatically controlled by the computer to monitor the pH value, DO value and anaerobic, microtrophic and anoxic environments in the reactor, and samples are taken through sampling ports 22, 23 and 24 to detect water Water quality and water flow are controlled by sol...
