Embodiment 1

[0197] Testing Equipment :

[0198] Ammonia nitrogen detection equipment such as Figure 4a shown, it includes:

[0199] Among them, for the sake of brevity, the casing of the device, the quantum dot spectral detection components (the quantum dot spectral detection device with about 60 channels, using an active light source, and the detector receiving transmitted light of 400-700 nm) and other components are not shown. Accessories. Such components or materials are commercially available.

[0200] The volume of the transparent reaction chamber above the electrolytic cathode is 2 mL (length, width 1 cm, height 2 cm), and a thymol blue color developer with a concentration of 0.7 mmol / L is placed.

[0201] In addition, an electrolytic anode (15mm*15mm in size, Pt electrode) is placed in the area where the pH needs to be increased in the ammonia nitrogen detection device, and the cathode is placed far enough away from it.

[0202] At the beginning of the detection, the direct...

Abstract

The invention relates to ammonia nitrogen detection equipment and a water quality detection method. The ammonia nitrogen detection equipment comprises an ammonia gas generation unit; an ammonia gas detection unit; the ammonia gas generation unit comprises an electrolysis electrode, and the electrolysis electrode electrolyzes a to-be-detected water body entering the ammonia gas generation unit to generate OH <-> under a current condition; the ammonia gas detection unit comprises an ammonia nitrogen detection part, the ammonia nitrogen detection part comprises a reaction cavity and a spectrum detection part, and the spectrum detection part is used for carrying out spectrum detection on the reaction cavity.

Description

technical field [0001] The invention belongs to the field of environmental protection, and specifically relates to the field of water quality monitoring of water bodies, especially river water, lake water and the like. Background technique [0002] With the increasing awareness of environmental protection, new requirements and challenges have been put forward for water quality monitoring of various natural water bodies, domestic or industrial wastewater, and secondary purified water. [0003] Whether it is natural water, such as river water, lake water, etc., or secondary purified water obtained after wastewater treatment, the control and detection of nitrogen content in it is one of the focuses of various environmental protection technology research or treatment. In actual detection or monitoring methods, the existing methods are usually based on field sampling, and then the determination of the content of various target elements or substances in water bodies is carried out...
