Abstract

The invention discloses a full-spectrum water quality online monitoring device. The device comprises a monitoring control host and a sensing probe electrically connected with the monitoring control host, the monitoring control host comprises a data display unit, a data output unit, a control unit, a data processing unit, a light source unit, a standard-added calibration unit and an analysis unit,the sensing probe comprises a probe body, an analysis chamber and a reflection unit, a beam splitter is arranged in the probe body, a transition position of the probe body and the analysis chamber isprovided with a plurality of photoscopes, a transition position of the analysis chamber and the reflection unit is provided with a plurality of arc reflectors, and a temperature sensor is arranged inthe analysis chamber. According to the device, a light source is externally arranged in the monitoring control host, a deuterium lamp is adopted, ultraviolet, visible and near-infrared broadband spectrums are generated, capacity control of the light source can be performed, and high-precision monitoring and analysis of multiple monitoring objects can be realized; and the arc reflectors are adoptedso that multiple times of reflection absorption of the spectrum in the analysis chamber can be realized, the absorption optical path is increased, and the analysis resolution of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of water quality monitoring, and in particular relates to a full-spectrum water quality online monitoring device. Background technique [0002] As one of the important tasks of environmental management, water quality monitoring is one of the important tasks of environmental management. Traditional water quality monitoring is basically single-factor monitoring through color chemical reaction methods, and the price of a single system is relatively high, and there are problems such as secondary pollution of waste liquid; full-spectrum water quality The online monitoring device is based on the real-time and rapid monitoring of the characteristic spectral absorption of the pollution factors in the water quality, and can simultaneously monitor COD, temperature, TOC, BOD, O3, ORP, turbidity, organic matter (benzene), nitrate nitrogen, chromaticity and other types Pollutant parameters do not produce secondary pollut...

Problems solved by technology

[0003] However, the spectrum of the existing full-spectrum water quality analysis equipment is usually directly integrated in the sensor probe. The spectral line bandwidth is narrow, the spectral ability is low, and it is not adjustable, resulting in equipment problems such as less monitoring content and low accuracy; secondly, the existing equipment The sensor probe adopts single optical path transmission spectral absorption analysis, and the spectral absorption optical path is small, resulting in low analysis accuracy of the equipment
