Water quality detection device and method based on laser-induced breakdown spectroscopy technology

Abstract

The invention discloses a water quality detection device and method based on a laser-induced breakdown spectroscopy technology, belongs to the field of marine water quality monitoring, and aims to solve the problem that coastal zone heavy metal elements and water pollution are difficult to automatically detect online in real time so as to decrease the risk of heavy metal pollution in seafood and reducethe risk of the heavy metal pollution in seafood the source. The device structurally comprises an unmanned ship, a visual detection module, a spectrum detection module and the like. According to the water quality detection device and method based on the laser-induced breakdown spectroscopy technology of the invention, a rasterized information transmission system is established on a coastal zone; map positioning is conducted on the unmanned ship after rasterizing treatment is conducted on the coastal zone; heavy metal elements and water quality in grids of the coastal zone are detected through the spectrum detection module; the content of the heavy metal elements in the coastal zone is analyzed through a non-standard analysis method; if the content exceeds the standard, the area is marked and early warning is performed; the effect of all-day real-time online automatic detection of the coastal zone is achieved; and the risks that the health condition of the human body is abnormal due to the heavy metal elements and water pollution are reduced.

Description

technical field [0001] The invention belongs to the technical field of coastal zone pollution monitoring, and in particular relates to a water quality detection device and method based on laser-induced breakdown spectroscopy technology. Background technique [0002] The nutritional value of seafood is very high, and many people especially like seafood, especially coastal residents, who eat seafood all year round. However, in recent years, due to a large amount of industrial wastewater or domestic sewage being discharged into the ocean, ocean water pollution has become increasingly serious, and organisms in the ocean will also be polluted to varying degrees, especially organisms near the coast, which gradually affect human health. According to the survey, in terms of elements, copper and zinc are the most common pollutants in aquatic products, and chromium is the lowest. These elements are highly toxic metal elements, and the harm to the human body is mainly chronic accumula...
