Description

Technical Field

[0001] This utility model relates to the field of sewage sampling equipment, and in particular to a portable sewage detection and sampling device. Background Technology

[0002] With the rapid advancement of industrialization and urbanization, the issue of sewage discharge has received increasing attention. Currently, there are many shortcomings in the existing technologies for sampling sewage in pipe wells. In such special environments as pipe wells, the sewage level is often low and the space is narrow, making it impossible for traditional large sampling equipment to enter. Therefore, small manual sampling tools are mainly used.

[0003] A common existing technique is to use sampling bottles with long ropes. The testing personnel tie the sampling bottles to the long ropes and then put them into the manhole. Gravity makes the sampling bottles sink into the sewage for sampling. The main problem with this method is that when the sewage level is low, it is difficult for the sampling bottles to accurately obtain sewage samples, which increases the difficulty and time cost of sampling.
