With the acceleration of urbanization and population growth, the discharge of domestic sewage continues to increase. Domestic sewage contains large amounts of organic matter, nutrients such as nitrogen and phosphorus, as well as microorganisms such as bacteria and viruses. If discharged directly without effective treatment, it can cause serious pollution to the aquatic environment, leading to eutrophication and damage to aquatic ecosystems. During sewage sampling, a sewage sampler with easily adjustable depth is required.

The utility model has a simple structure and is easy to operate. Under the action of the sampling mechanism and the adjustment mechanism, the bottom water inlet sampling method can prevent the upper layer of sewage from replacing the lower layer, which is convenient for use. This patent solves the problems of complex structure, many parts, and inconvenient operation;

[0004] Although the above utility model patent solves the problems of complex structure, many parts and inconvenient operation, the sewage sampler in the prior art is not convenient for sampling sewage of different depths. During use, the sewage concentrations at different depths in the sewage pool are different. If the sewage at different depths cannot be sampled, it will lead to inaccurate test results in the later stage, making the sampler less practical and less accurate, and it is not convenient to fix the sampler on the side of the sewage pool. During use, if it is not convenient to fix the sampler on the side of the sewage pool, the sampling tube will be unstable during the lifting process, thereby making the sampling tube unable to perform normal lifting work, resulting in poor stability of the sampler.
