The hot air is discharged through multiple injection holes to ensure that the inner and outer walls of the water intake pipe and the detection tube can be fully dried. At the same time, the ultraviolet disinfection lamp disinfects the inner wall of the pipeline, which improves the disinfection effect and the efficiency of drying and disinfection. Through drying and disinfection, the moisture and bacteria inside the water intake pipe and the detection tube can be quickly removed, avoiding the influence of residual moisture on subsequent detection, and improving the efficiency and accuracy of water quality detection.

[0027] 5. In the present invention, an E. coli detector and a water sample ORP detection module are provided inside the water quality detector body. During detection, water samples are collected through the sampling component and sent to the E. coli detector and the ORP detection module respectively. The water quality detector body detects the fecal coliform count of the water sample to ensure that the fecal coliform count in the effluent is less than 1000 / L and meets the discharge standard. The ORP detection module measures the ORP value of the water sample in real time, records and saves the data, and establishes the corresponding relationship between the fecal coliform count and the ORP value through multiple detections. In particular, when the fecal coliform count is just less than 1000 / L, the ORP value at this time is recorded as a reference standard. In actual production, the amount of disinfectant added at the outlet of the sewage treatment plant is adjusted according to this reference standard. When the ORP value displayed by the online instrument is lower than the reference standard, the amount of disinfectant added is increased; otherwise, it is appropriately reduced to ensure that the effluent water quality is stable and meets the standard, thereby reducing the frequency and cost of detection and improving the efficiency and accuracy of water quality monitoring.

After the water intake pipe (613) is moved to a suitable water intake height, the piston rod of the electric push rod (620) moves upward, so that the push block drives the sealing block (614) and the positioning rod (615) to move upward, and the positioning rod (615) moves along the positioning groove (613). 6) sliding to separate the sealing block (614) from the top surface of the water intake pipe (613), allowing the disinfected water to enter the water intake pipe (613), returning the sealing block (614) to the initial position after sampling, sealing the water inside the water intake pipe (613), sampling and testing water at different depths, pouring the sampled water into the corresponding test tube (806), placing the test tube (806) inside the water quality tester body (10) to test the disinfected water; Cleaning: before and after the detection, the corresponding water intake pipe (613) and the detection pipe (806) are respectively inserted into the hollow pipe (16) of the cleaning tank (704) in reverse, so that the pipe openings of the water intake pipe (613) and the detection pipe (806) are in frictional contact with the top surface of the first hollow block (708), and the sealing cover (19) on the cleaning tank (701) is closed. At this time, the water inside the water tank (702) is sucked by the water pump (705) and transported to the inside of the hollow pipe (16) and the annular pipe (15) through the connecting pipe (18), and then sprayed to the outside from the spray hole (17). The water sprayed through the spray hole (17) cleans the inner and outer walls of the water intake pipe (613) and the detection pipe (806), and the cleaned water is discharged to the outside through the drainage groove (707); Disinfection and storage: After cleaning, the water intake pipe (613) and the detection tube (806) are respectively inserted into the outside of the hollow tube (16) of the drying tank (802) in an inverted state, so that the water intake pipe (613) and the detection tube (806) are in friction contact with the top surface of the second hollow block (807), and the sealing cover (19) on the storage box (801) is closed. The blower (803) sucks the external air through the air inlet pipe (809) and transmits it to the connecting pipe (18), and the air heater (808) heats the transmitted air, so that the hot air enters the drying tank (802). The liquid inside the connecting tube (18), the annular tube (15) and the hollow tube (16) is discharged from the injection hole (17), and the inner and outer walls of the cleaned water intake pipe (613) and the detection tube (806) are dried. During the drying process, the water intake pipe (613) and the detection tube (806) are disinfected by the ultraviolet disinfection lamp (14). After the drying process is completed, the water intake pipe (613) and the detection tube (806) are respectively inserted into the corresponding placement groove (805) for collection. After the collection process is completed, the sealing cover (19) is replaced and the inner walls of the stored water intake pipe (613) and the detection tube (806) are disinfected by the ultraviolet disinfection lamp (14).

10. The detection method according to claim 9, It is characterized in that The water quality detector body (10) is provided with an E. coli detector and a water sample ORP detection module. During detection, a water sample is collected through a sampling component (6) and sent to the E. coli detector and the ORP detection module respectively. The E. coli detector detects the number of fecal coliform bacteria in the water sample, and the ORP detection module measures the ORP value of the water sample in real time. The method also includes the following steps: The number of fecal coliform bacteria in the water sample is detected by an E. coli detector, and the ORP value of the water sample is measured in real time by an ORP detection module. Through multiple tests, the corresponding relationship between the number of fecal coliform bacteria in the water sample and the ORP value is established. In particular, when the number of fecal coliform bacteria in the water sample is just less than 1000 / L, the ORP value at this time is recorded as a reference standard.
