Description

Technical Field

[0001] The utility model relates to the field of detection devices, in particular to a sampling detection device for printing and dyeing wastewater treatment. Background Art

[0002] Printing and dyeing wastewater refers to the wastewater discharged from various processes in the printing and dyeing process. The printing and dyeing industry uses a large amount of chemical agents and dyes in the production process. These substances are mixed with water during the production process to form wastewater with complex components. Printing and dyeing wastewater usually contains dyes, pulp, auxiliaries, fiber impurities, oils, acids, alkalis, inorganic salts and other pollutants.

[0003] Printing and dyeing wastewater treatment refers to the purification and treatment of wastewater generated by the printing and dyeing industry through a series of physical, chemical and biological methods to ensure that it meets the national emission standards or water quality requirements for reuse. If printing and dyeing wastewater is discharged directly without effective treatment, it will cause serious pollution to the environment, destroy the ecological balance of water bodies, and affect human health. Therefore, during the printing and dyeing wastewater treatment process, regular sampling and testing of the wastewater is required to monitor the treatment effect and water quality.

[0004] However, when the existing printing and dyeing wastewater sampling and detection device is used, it is not conducive to timely flushing of the sampling and detection device. After the sampling and detection device samples and detects the printing and dyeing wastewater, the printing and dyeing wastewater is likely to remain in the sampling and detection device. The printing and dyeing wastewater remaining in the sampling and detection device will affect the accuracy of the sampling and detection device in subsequent printing and dyeing wastewater detection.

[0005] Therefore, we proposed a sampling and detection device for printing and dyeing wastewater treatment. Utility Model Content
