[0001] The utility model relates to the technical field of water quality monitoring, in particular to a sewage ammonia nitrogen monitor. Background Technique

[0002] Ammonia nitrogen wastewater mainly comes from chemical fertilizers, coking, petrochemical, pharmaceutical, food, landfill sites, etc. A large amount of ammonia nitrogen wastewater discharged into water bodies not only causes water eutrophication and makes the water body black and smelly, increasing the difficulty and cost of water treatment, but also has a toxic effect on humans and organisms. The treatment processes for ammonia nitrogen wastewater (before 2014) include various treatment processes such as biological methods and physicochemical methods.

[0003] There are various methods for monitoring the ammonia nitrogen content in sewage. For example, the patent number is CN217586898U, and the patent name is an on-line monitor for ammonia nitrogen in sewage and rainwater. By setting a semiconductor laser, the semiconductor laser emits laser light that passes through the sewage and is received by a photodetector and converted into an electrical signal to achieve the monitoring of the nitrogen content in the sewage. However, the number of semiconductor lasers in the device is one, and it irradiates from top to bottom, with limited monitoring accuracy. If the components in the sewage are uneven, the monitoring effect is even worse.

[0004] Therefore, a sewage ammonia nitrogen monitor is proposed. Content of the Utility Model
