Embodiment Construction

[0041] An online monitoring instrument of a heavy metal of water quality, consisting of online sample dissolution system A. Online sample detection system B. Measurement and control system C. The online water sample after physical pre -processing (ie crime, emulsification, filtering) is measured onUnder the action of the control system, first enter the online sample dissolution system A, so that the mercury, lead, cadmium, chromium, and arsenic in the water sample will be resolved into the corresponding ion state, and then enter the online sample detection system."And" spectral analysis "detection of the measured metal content, instrument integrates national standard detection methods, due to the characteristics of the characteristic absorption wavelength corresponding to the tested color rendering substances corresponding to the each of the monotherapy substances (mercury: 485nm, lead, lead, lead, lead (485nm, lead, lead: 535nm, cadmium: 518nm, chromium: 540nm, arsenic: 530nm). T...

Abstract

The invention discloses a water quality heavy metal multi-parameter online monitoring instrument which comprises an online sample digestion system, an online sample detection system and a measurement and control system. The water quality heavy metal multi-parameter online monitoring instrument disclosed by the invention can realize automatic online monitoring of content of heavy metals such as mercury, lead, cadmium, chromium and arsenic in water, can be widely applied to the fields of surface water quality pollution monitoring, seawater pollution monitoring, up-to-standard release monitoring of industrial wastewater treatment and municipal sewage treatment and the like and has the advantages of high functional expansibility, wide measurement range and low cost.

Description

Technical field [0001] The invention is a kind of water quality metal multi -parameter online monitoring instrument involving the field of water quality monitoring instruments. Background technique [0002] The five types of heavy metal pollution of heavy metals, especially mercury, lead, cadmium, chromium, and arsenic, which will directly affect the safety of the water ecological environment and the safety of drinking water sources, cause the aquatic creature, or be rich in aquatic creatures.In the body, the food chain is seriously endangered through the food chain. Therefore, heavy metals are the water quality parameters that need to be strictly monitored. In recent years, the water quality heavy metal pollution incident has been frequent, which has been highly valued by the Chinese government. The Minister of Environmental Protection Zhou ShengxianIt has been said that the goal of the "Twelfth Five -Year Plan" heavy metal pollution prevention is to establish a relatively compr...
