Water quality detection system based on ultraviolet visible spectrum detection

Abstract

The invention discloses a water quality detection system based on ultraviolet visible spectrum detection. A first spectrum testing unit and a second spectrum testing unit respectively comprise a light source, a detection probe and a spectrometer and are connected with a first industrial computer and a second industrial computer respectively, both the first industrial computer and the second industrial computer are connected with a main control computer, the main control computer is respectively connected with an alarm device, a storage module, a display module and an instrument control module, the instrument control module is respectively connected with a cleaning system and a flow path system, the cleaning system is connected with the flow path system, and a sample pretreatment device is connected onto the flow path system. The two testing units and the two industrial computers are added, large data errors caused by faults are prevented, the main control computer gives an alarm to remind a worker of large testing errors when the errors are large, the worker detects whether instruments are damaged or improperly operated or not, the problem of detection errors is solved, and the water quality detection system is convenient to use.

Description

technical field [0001] The invention relates to the technical field of environmental protection systems, in particular to a water quality detection system based on ultraviolet-visible spectrum detection. Background technique [0002] Water quality analysis is to measure and evaluate the quality status and change law of water resources, and provide scientific basis for the development, utilization, management and protection of water resources by the country and governments at all levels. The quality of water resources is usually described by water quality indicators, commonly used water quality indicators include chemical oxygen demand (COD, Chemical Oxygen Demand), total organic carbon (TOC, TotalOrganic Carbon), nitrate nitrogen (NO3-N), turbidity (TURB) and other indicators. my country's national standard method uses chemical analysis methods for the detection of many water quality indicators. For example, COD uses permanganate index or potassium dichromate method, and n...
