AI Technical Summary

Problems solved by technology

Manual on-site sampling laboratory analysis and testing methods, analysis of independent samples, limited by sampling methods and equipment, requires high labor costs and time consumption
The in-situ detection of the buoy mooring sensor can obtain in-situ continuous data of a fixed-point natural water body, but the long-term work has serious biological adhesion and requires manual and regular maintenance, so the equipment and maintenance costs are relatively high

Abstract

The invention discloses an underway continuous treatment, sampling and multi-parameter water quality monitoring device for seawater. The device is characterized by comprising a seawater flow diverter,a peristaltic pump, a detection tank, sensors, an ion field effect pH meter, an ultraviolet nitrate instrument, a communication antenna, a GPRS data transmission antenna, a positioning communicationantenna, a data acquisition and power control box and a pCO2 pressure divider. According to the method, the real-time property of data is high, labor and time are saved, the maintenance cost is lowerthan that of an in-situ sensor detection method, and data quality is easier to control. The device can be conveniently carried on a scientific research ship, a merchant ship or a fishing boat, so thatmost of global oceans can be covered, and precious data are acquired.

Description

technical field [0001] The invention relates to the field of water body detection, in particular to a mobile seawater continuous processing, sampling and multi-parameter water quality monitoring device. Background technique [0002] With the increase of global climate change and human activities, the water quality of the ocean surface water body is also undergoing significant changes, such as nitrate, ammonium salt, active phosphate, silicate and other nutrients input intensified, eutrophication, harmful red tide , Water hypoxia and other ecological disasters occur frequently. The annual increase of atmospheric carbon dioxide has also made ocean acidification more and more serious, and the carbon flux at the air-sea interface has changed significantly. Therefore, it is urgent to carry out high-resolution continuous automatic monitoring of marine water quality in order to carry out research and governance on the deterioration of the marine environment. [0003] At present, t...
