The second branch pipe 18 is connected to the first water sampling pipeline 13, and the first branch pipe 17 and the second branch pipe 18 are respectively provided with a third water sampling valve 19 and a fourth water sampling valve 20, and the two first water sampling bottles 14 are also respectively provided with a first liquid level sensor (not shown in the figure) and a second liquid level sensor (not shown in the figure); the cleaning pipeline 5 is connected to the first water inlet pipeline 4, and a cleaning pump 21 and a cleaning valve 22 are provided on the cleaning pipeline 5; the sewage outlets of the grit chamber 1 and the preliminary inspection tank 2 are both connected to the sewage pipe 23, and a sewage valve 24 is provided on the sewage pipe 23; the controller controls the operation of the first water sampling valve 15, the first water sampling pump 16, the first water inlet valve 10, the first water inlet pump 11, the cleaning valve 22, the cleaning pump 21, the diaphragm pump 12, the pH value sensor, the third water sampling valve 19, the fourth water sampling valve 20, the first liquid level sensor, the second liquid level sensor and the sewage valve 24.

[0035] Specifically, when used, the first water inlet pump 11 and the first water inlet valve 10 are opened through the controller, and the external water sample enters the sand settling tank 1 from the first water inlet pipe 4, and enters the initial inspection tank 2 from the overflow port as the water level in the sand settling tank 1 rises.

At this time, the first water inlet valve 10 and the first water inlet pump 11 are closed by the controller, and the second water inlet valve 36 and the second water inlet pump 37 are opened to complete sampling.
