Beschreibung
Zusammenfassung:	The utility model discloses a risk control and denitrification system for dissolved oxygen in sewage. The system comprises a deoxidation tank, a denitrification biofilter and a PLC (Programmable Logic Controller), the denitrification biofilter is connected with the deoxidation tank, a dissolved oxygen concentration detector is arranged in the deoxidation tank, and the dissolved oxygen concentration detector is in data connection with the PLC; the denitrification biological filter receives the sewage deoxidized by the deoxidation tank, and a total nitrogen online detector is arranged in the denitrification biological filter and is in data connection with a PLC (Programmable Logic Controller). According to the risk control and denitrification system for dissolved oxygen in sewage provided by the embodiment of the invention, the deoxidation mode of the deoxidation tank can be adjusted according to the specific dissolved oxygen concentration value, so that the cost of controlling the concentration of dissolved ox
