Description

TECHNICAL FIELD

[0001] The application relates to a water quality detection technology field, in particular to a water nitrogen element detection device. BACKGROUND

[0002] Wastewater refers to water discharged in the process of resident activities and runoff rainwater. It includes domestic wastewater, industrial wastewater and initial rain runoff into drainage pipes and other useless water. Generally, it refers to water that cannot be recycled or treated after primary pollution and the difficulty of pure treatment does not reach a certain standard. The ammonia nitrogen tester is a mechanical equipment suitable for large, medium and small water plants, industrial and mining enterprises, and ammonia nitrogen concentration detection of domestic or industrial water in order to control the ammonia nitrogen of water to reach the specified water quality standard. The ammonia nitrogen detection device in the wastewater is not convenient for storing sample test tubes due to poor overall connectivity of the detection device.

[0003] In view of the above problems, through retrieval, the patent with publication number CN216411270U discloses a wastewater ammonia nitrogen detection device, which relates to the technical field of wastewater detection. The wastewater ammonia nitrogen detection device comprises a device main body, a detection door movably installed at the top end of the device main body, a turnover door movably installed at the front end of the device main body, a cavity formed in the inside of the device main body, a placing rack placed at the inside bottom end of the cavity, a disinfection lamp fixedly installed at the inside top end of the cavity, a sliding block fixedly installed at the bottom end of the placing rack, a sliding groove formed at the inside bottom end of the cavity, the sliding groove and the sliding block being in sliding connection, a placing groove formed at the top end of the placing rack, and a control panel fixedly installed at the top end of the device main body close to the detection door.

[0004] Based on the above patent and combined with the existing findings, the following problems exist:

This method relies on manual operation and has certain requirements for operation experience. The shaking methods of different experimenters are different. The whole process needs to take out the test tube and then fix the test tube again, which consumes time and affects the detection efficiency.

[0006] (2) When the solution is prepared, the pH value of the water sample needs to be compared. The existing method requires the tester to hold the test paper and colorimetric card to a position where the light is reliable for visual judgment. This method is relatively cumbersome and needs to be improved. SUMMARY
