Abstract

The invention provides a total phosphorus and total nitrogen integrated and automatic measurement system and an automatic measurement method thereof, and the system comprises a total phosphorus measurement module, a total nitrogen measurement module, and a control mainboard module which is in communication connection with the total phosphorus measurement module and the total nitrogen measurement module. Each of the total phosphorus measurement module and the total nitrogen measurement module comprises a sample introduction device and a solution transfer device connected with the sample introduction device, and the total phosphorus measurement module and the total nitrogen measurement module share a high-pressure digestion device. The total phosphorus and total nitrogen can be integrally and automatically measured, the problems of article damage, low efficiency, potential safety hazards and the like caused by frequent uncovering of the high-pressure digestion device are avoided, and the contact of operators with related toxic reagents is reduced.

Description

technical field [0001] The invention relates to the technical field of water quality detection, in particular to a total phosphorus and total nitrogen integrated and automatic measurement system and an automatic measurement method thereof. Background technique [0002] Excessive total phosphorus and total nitrogen in water will lead to eutrophication of water, resulting in excessive algae reproduction and red tide phenomenon; nitrate in total nitrogen will be reduced to nitrite in the human body, and nitrite will be formed with protein in the human body. Nitrosamines are strong carcinogens; drinking water with too high total phosphorus content will lead to calcium loss, vomiting, diarrhea and even death from poisoning. Therefore, the content of total phosphorus and total nitrogen in the water body needs to be monitored. [0003] The traditional measurement method of total phosphorus and nitrogen requires manual loading of the water sample to be tested into a special digesti...
