The sedimentation tank 43 is arranged at a position close to the bottom of one side far away from the visual angle direction, and the detection tank 46 is arranged at a position close to the top of the same side.

The water intake pipe 51 penetrates into the cabinet body from the bottom of the collection area 4, and is connected with the primary filtering unit 41 and the water inlet of the primary pump 42 in sequence. The outlet pipe of the primary pump 42 extends from the bottom to the top across the side wall of the settling tank 43, extends into the settling tank from the top opening thereof, and extends to a position close to the bottom of the settling tank 43.

The sedimentation tank 43 is a circular tank with an open top, a conical slope is arranged inside the circular tank, and a drainage pipeline 52 which downwards penetrates through the cabinet body to the outside is arranged at the bottom of the slope, namely the center of the bottom of the sedimentation tank 43. The drain line 52 is provided with a first solenoid valve 53. The bottom of the sedimentation tank 43 is provided with a vertical column for mounting the first electromagnetic valve 53.

The water inlet pipe of the secondary pump 45 extends into the sedimentation tank 43 from the top thereof, and only extends into the sedimentation tank 43 near the top thereof for taking supernatant. The outlet pipe of the secondary pump 45 is connected to the secondary filter unit 44 and extends from the top of the detection cell 46 into the detection cell 46 to a position near the bottom of the detection cell 46.

The detection pool 46 is a circular pool with an open top, but a cover plug is arranged at the top, and the cover plug is provided with a water outlet pipeline for the secondary pump 45, a sample reserving pipeline for sample reserving equipment and a through hole for the probe of the detection equipment to pass through. The bottom of the detection cell 46 is also provided with a tapered slope, but the bottom of the slope is positioned close to the left side wall of the detection cell 46.
