Description

Technical Field

[0001] The present invention relates to the technical field of water pollution detection, and particularly to a sampling device for detecting pollutants in wastewater. Background Art

[0002] In the current booming development of modern industry, various industrial activities generate a large amount of wastewater containing complex pollutants. If this wastewater is discharged into natural water bodies without effective treatment, it will cause serious damage to the ecological environment, threatening human health and ecological balance. To accurately control the pollution status of wastewater, it is crucial to scientifically and efficiently detect the content of pollutants in wastewater, and obtaining a representative water sample is the key prerequisite for detection.

[0003] Traditional wastewater sampling methods have many limitations. In the detection of water bodies such as rivers and lakes, conventional water quality detection sampling equipment usually uses sampling buckets made of glass or plastic. Staff collect surface water or groundwater by hand-carrying the sampling bucket, and after collection, it is covered and sealed to ensure that the sample is not contaminated during transportation. However, most of this collection method can only collect water samples with a relatively shallow depth on the riverbank. When staff want to obtain deeper water samples, they need to wade into the water. When staff wade into the water, they face risks such as drowning, slipping, and falling into the water.

[0004] To solve the above problems, it is extremely urgent to develop a sampling device that can break through the limitations of traditional sampling, efficiently collect deep water samples, and adapt to complex wastewater environments. This has important practical significance for improving the accuracy and reliability of wastewater pollutant detection and strengthening water resource protection and pollution control.
