Description

Technical Field

[0001] The utility model relates to the technical field of sewage sampling, in particular to an environmental sewage sampler for environmental engineering. Background Technique

[0002] Environmental sewage sampling refers to the process of collecting water samples from sewage systems for analysis and monitoring. These samples can be used to analyze the composition of sewage, evaluate water quality, monitor pollutant concentrations, trace pollution sources, evaluate sewage treatment effects, and conduct other environmental studies.

[0003] When the existing sewage sampling device samples sewage, it can sample at most one collection bottle at a time. When multiple samplings of sewage at different depths are required, it takes time to replace different collection bottles for sampling. Moreover, due to the large amount of impurities in the sewage, the sampler is prone to blockage during the extraction process.

By setting multiple sets of collection devices, it is convenient to perform multi-bottle sampling during a single sampling process. By setting a filtering structure at the sampling port of the sampler, the sampler can be prevented from being blocked. Content of the Utility Model
