Black and odorous water body ammonia nitrogen release research device

Abstract

The invention relates to the field of water environment detection, in particular to a black and odorous water body ammonia nitrogen release research device which is used for detecting ammonia nitrogenof bottom mud and is arranged on the bottom mud during detection. Ultra-pure water is stored in a first release box and a second release box. Ammonia nitrogen in the bottom mud is diffused to the ultra-pure water in the first release box and the second release box in sequence, and the ammonia nitrogen moves from the first release box to the second release box to form a gradual diffusion and dilution process, that is, the ammonia nitrogen concentration in the first release box is higher than that in the second release box. A first power assembly pumps water samples containing ammonia nitrogenin the second release box and the first release box into a detection box respectively, ammonia nitrogen concentration detection is conducted through an ammonia nitrogen probe, and different ammonia nitrogen concentration data can be obtained. Therefore, the release detection of the ammonia nitrogen content in the bottom mud can be realized without collecting the bottom mud, so that the adverse effect in the bottom mud transportation process is improved, and the detection error caused by bottom mud transportation is improved.

Description

technical field [0001] The invention relates to the field of water environment detection, in particular to a device for researching the release of ammonia nitrogen in black and odorous water bodies. Background technique [0002] In the testing of water environment, the content of ammonia nitrogen in the sediment is also a very important testing indicator. In areas with serious water pollution, the content of pollutants exceeds the self-purification capacity of the water body, and the water body produces black and odorous phenomena. [0003] When detecting the ammonia nitrogen content in the sediment in related technologies, it is usually necessary to collect the sediment from the bottom of lakes and rivers, and then measure the ammonia nitrogen content. During the process of collecting the sediment and transporting it to the laboratory for ammonia nitrogen detection, it is easy to The actual content of ammonia nitrogen in the sediment will cause adverse effects and easily ca...
