Ultraviolet-visible spectrum in situ monitoring device capable of adjusting optical path and water quality multi-parameter measuring method

Abstract

The invention discloses an ultraviolet-visible spectrum in situ monitoring device capable of adjusting an optical path and a water quality multi-parameter measuring method. The monitoring device comprises a monitoring part, a light source, a collimating lens, a converging lens, an emitting part, a flat field holographic concave grating and an image detector; a monitoring probe is arranged in waterto be detected; and a second sub-chamber is filled with the water to be detected. The light source is arranged for supplying illumination, the light emitted by the light source is collimated by the collimating lens to become parallel beams, the parallel beams pass through the water to be detected in the second sub-chamber, then are converged by the converging lens and are emitted from emitting slits of the emitting part, the light emitted from the emitting slits is divided through the flat field holographic concave grating and is imaged on a light-sensitive surface of the image detector, theimage detector converts light intensity signals with different wavelengths into electrical signals, namely an ultraviolet-visible spectrum, and a controller acquires and records ultraviolet-visible spectrum signals. The monitoring device is greatly improved in monitoring efficiency and high in measurement accuracy.

Description

technical field

[0001] The invention relates to the field of environmental monitoring, in particular to an ultraviolet-visible spectrum in-situ monitoring device with adjustable optical path and a water quality multi-parameter measuring method. Background technique

[0002] In the field of water environment monitoring, automatic monitoring of water bodies such as rivers, lakes, reservoirs, groundwater, and coastal waters includes sampling monitoring and in-situ monitoring. Sampling monitoring adopts the automatic sampling system to periodically collect water samples, and the monitoring equipment analyzes the water samples. There are problems such as long monitoring period, high power consumption of moving parts, complex system, large maintenance, and pipeline blockage and aging; in-situ monitoring It has unique advantages, including real-time monitoring, few moving parts, low power consumption, simple system, and low maintenance, especially when using ultraviolet-visible spe...
