Four layers of filter screens 2 are arranged in the connecting pipe 1, and meshes of the filter screens 2 are sequentially reduced along the water inlet direction towards the water outlet direction. And the filtering sand 3 is filled between two adjacent filter screens 2, and the particle size of the filtering sand 3 is smaller than the mesh diameter of the filter screens 2. The flushing pipe 4 communicates with the connecting pipe 1 and is located at an end close to the sampling pipe. The quick-release connector 5 is arranged at one end of the water inlet of the flushing pipe 4, and the valve 6 is arranged on the quick-release connector 5.

When in use, one end of the connecting pipe 1 is connected with one end of the sampling pipeline, and the valve 6 arranged on the quick connector after the connecting pipe 1 is connected is in a closed state. The filter device is placed in a sewage tank for sampling, sewage passes through the filter screen 2 and then passes through the filter sand 3 arranged between the filter screens 2. The impurities in the sewage are filtered through the filtering sand stone 3, and the filtering cleanliness degree of the impurities in the sewage is related to the particle size of the sand stone, so that the filtering sand stone 3 meeting the particle size requirement is more required to be selected. In order to avoid sand and stone running during sampling, the particle size of the filter sand 3 is larger than that of the filter screen 2. After the sampling is completed, clean water is connected into the filter screen 2 and the filter sand 3 through the flushing pipe 4 to perform back flushing, so that the filter device is convenient for secondary use.
