Eutrophicated water bodies are black and smelly and difficult to treat. They are toxic to humans and organisms. When quickly testing the ammonia nitrogen content in wastewater, the wastewater is generally placed in a test tube, and then the detection reagent is dripped into the test tube. The test tube is shaken to fully mix the detection reagent and wastewater and perform colorimetry.
