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...
