Description

Technical Field

[0001] The utility model relates to the technical field of chemical wastewater detection, in particular to a chemical wastewater detection device. Background Art

[0002] Chemical wastewater refers to wastewater produced in the process of producing products in chemical plants, such as oily wastewater from the production of ethylene, polyethylene, rubber, polyester, methanol, ethylene glycol, oil tank areas, air separation and air compression stations, etc. After biochemical treatment, it can generally meet the national secondary emission standards and is now mostly used for biochemical treatment. Chemical wastewater has complex components and contains a variety of toxic and harmful substances, such as cyanide, phenol, arsenic, mercury, cadmium and lead.

[0003] Chemical wastewater needs to be sampled during testing. Existing sampling devices can only test chemical wastewater at the same depth, but cannot sample wastewater at different depths. Since only wastewater at the same depth can be sampled, the water quality data obtained may not fully reflect the true situation of the entire sewage pool or sewage fluid. Sewage at different depths may have different pollutant concentrations, types and distributions. Therefore, sampling only from a single depth may result in data distortion or omissions.
