[0003] Generally speaking, before sewage is treated or discharged, sewage needs to be sampled and detected to determine the degree of pollution of sewage or whether it meets the discharge conditions, etc., at which time sewage sampling and detection equipment needs to be used to sample sewage. For example, the invention patent with publication number CN107219097A discloses a sewage sampling and detection device, which comprises wheels, a bottom support, a partition, a fixed frame, test paper, a sampling device, a moving device and a top support.

The top support is arranged on the left side of the moving device. The fixed frame is connected to the moving device. The partition is arranged in the middle of the fixed frame. The sampling device is used to sample sewage. The moving device drives the fixed frame to move left and right, and the sewage is uniformly dropped on the test paper. The detection is more accurate. The test paper changes color. The standard color comparison card is placed in the fixed frame in front of the partition. People can compare the color change of the test paper with the color comparison card to determine the pH value of the sewage, and then determine whether the sewage is acidic or alkaline. People can adjust the pH value of the sewage according to its acidity or alkalinity. The pH value of the sewage should be between 6 and 9 to meet the discharge standard.

The sampling method according to any one of claims 1 to 6, wherein The method comprises the following steps: S1, sampling: since one end of the liquid suction pipe (411) located inside the treatment bin (3) is communicated with the liquid guide tank (51), and the liquid guide tank (51) is communicated with the air pump (52), during the process of pumping the liquid guide tank (51) to vacuum by the air pump (52), the liquid suction pipe (411) extending into the sewage can extract the sample into the liquid guide tank (51) for storage, and during the liquid sampling process, the driving motor (44) drives the telescopic rod (46) to rotate, which can stir and treat the sewage to improve the uniformity of the sewage turbidity; S2, adjusting: by locking the telescopic rod (46) through the adjusting screw rod (49) on the telescopic rod (46), the electric push rod (47) can be started to push and pull the telescopic rod (46) to rotate and adjust on the rotating seat (42), which can adjust the liquid suction angle of the liquid suction pipe (411), and by locking the rotating seat (42) through the right adjusting screw rod (49), the length of the telescopic rod (46) can be adjusted through the telescopic adjustment of the electric push rod (47), which can adjust the sampling depth, and by cooperating with the movement of the treatment bin (3), the sampling direction can be adjusted in multiple directions; S3, filtering: pumping the sewage sample in the guide liquid tank (51), when discharging through the drain pipe (53), the double shaft motor (57) can drive the guide liquid tank (51) to vibrate through the cooperation of the rotating disc (58) and the connecting rod (59), so that the sample can be vibrated and screened by the filter screen (55) in the drain pipe (53) during discharging, to filter the impurities in the sewage sample, reduce the content of solid impurities in the sample, and improve the detection convenience and accuracy; S4, sample storage: place the sampling box (63) on the placement plate (62), and when the door plate (61) is closed, the placement plate (62) can be driven to slide through the supporting rod (64), so that the sampling box (63) is driven to the lower side of the guide liquid frame (54) for sampling the sewage sample, and the sampling box (63) after sampling can be placed in the storage box (7) for closed storage.
