Integrated probe type photoelectric water-quality multi-parameter online measuring system

Abstract

The invention discloses an integrated probe type photoelectric water-quality multi-parameter online measuring system. The integrated probe type photoelectric water-quality multi-parameter online measuring system comprises a control and data acquiring unit and an optical system unit, wherein the control and data acquiring unit comprises an upper computer, a control and data acquiring unit and an acquiring device, the optical system unit comprises a composite light source and a light path, the composite light source comprises a left light source and a right light source, the left light source is an LED array composed of many LED light sources different in wavelength, and the right light source is composed of ultraviolet LED light sources and near-infrared LD (laser diode) light sources. The upper computer controls the light source to emit different wavelengths of light to irradiate water body to be detected by the control and data acquiring unit and triggers substances of the water body to be detected to emit fluorescent and scattered light signals. The integrated probe type photoelectric water-quality multi-parameter online measuring system has the advantages that direct detection can be realized without any chemical reagent, data detection is fast and complicated steps are avoided. Meanwhile, detection of types and concentration of various algae in the water and online detection of hydrocarbon content and turbidity can be completed; detection can be independent and accurate, and different needs of environment monitoring are met.

Description

Technical field [0001] The patent of the invention relates to an online in-situ detection device, specifically an online in-situ measurement system for water quality. technical background [0002] With the rapid development of the national economy, the economy has taken off, and the productivity has increased, the water quality and environment of our country have also suffered severe damage. Industrial wastewater discharge, increased navigation, and oil spills have caused eutrophication and increased hydrocarbon content in water bodies, resulting in excessive phytoplankton in the water body, causing frequent red tides in coastal waters in recent years, and excessive phytoplankton depleting dissolved oxygen in the water , Resulting in frequent deaths of a large number of aquatic organisms. In the fields of aquaculture, environmental monitoring, medical and health, and scientific research, it is necessary to grasp the changes of various parameters in the water body in real time fo...

Problems solved by technology

At present, the instruments for measuring water quality by spectrometry are basically monopolized by western developed countries. Compared with them, my country's spectrometry water quality environment detection and sensor technology are backward, and lack independent intellectual property rights with reasonable price, comprehensive analysis parameters, real-time, fast and accurate This situation seriously restricts the monitoring and control of the water quality environment
