[0002] Wastewater refers to the general term for water discharged during residents' activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other unused water such as initial rain runoff into drainage pipes. It generally refers to water that cannot be recycled after certain technical treatment or water that is difficult to purify after primary pollution and does not meet certain standards. Heavy metal ions often exceed the standard in wastewater, and some wastewater also contains a large number of microorganisms. For such wastewater, it is necessary to sample the wastewater to determine how much it exceeds the standard, and then place it on the detector for measurement. However, the existing wastewater sampling process is too simple, and generally a plastic straw is used to simply absorb trace amounts of wastewater. This method is prone to cause imbalance in the wastewater and affect subsequent wastewater testing.

[0003] Therefore, in response to the above problems, research and development of wastewater sampling technology was carried out. Utility Model Content
