[0029] Working principle: This wastewater treatment multi-level sampling device;

[0030] When performing multi-level sewage sampling, the installation pipe 2 is first placed into the sewage. Using the sliding structure of the U-shaped rod 3 on the installation pipe 2, the positioning rod 19 is pulled, causing the spring 18 to extend and retract elastically, thus canceling the insertion and positioning with the slot 20. At this point, the U-shaped rod 3 can be raised and lowered on the outside of the fixed column 4 and the inside of the installation pipe 2. This allows the lifting groove 9 to descend according to the different depths of the sewage, adjusting the sampling depth of the sampling head 14. After adjusting to the specified depth, the positioning rod 19 is released and reset under the elastic restoring force of the spring 18, inserting into the slot 20 to position the U-shaped rod 3. Then, by starting the water pump 6, and connecting the sampling pipe 5, the connecting pipe 10, and the sampling head 14, the sewage at the adjusted depth can be sampled. The sewage passes through a double-layer filter of the filter head 15 and the gauze filter bag 16, automatically filtering out impurities and sediment, improving the accuracy of sewage sampling, increasing the convenience of sampling operations, and enhancing the efficiency of subsequent testing.
