"Industrial discharge wastewater heavy metal online monitoring technology system" passed the acceptance
[ China Instrument Network Instrument Development ] On November 23, the Anhui Science and Technology Plan Project “Industrial Wastewater Heavy Metal Online Monitoring Technology System†undertaken by Anhui Researcher of Anguang Institute passed the expert acceptance organized by the Science and Technology Department of Anhui Province.
Online monitoring demonstration operation
In response to the demand for monitoring of pollution sources and on-line monitoring technologies and equipment for key pollution sources in the implementation of heavy metal pollution reduction in the industry, the project is based on laser-induced breakdown spectroscopy, using graphite substrates as water-like carriers, by automatically loading and unloading graphite substrates. , water sample automatic injection and accurate titration, sample drying, spectral measurement and analysis, to achieve continuous online automatic detection of heavy metal content of wastewater. The project designed the sample-specific workbench and electromagnetic heating enrichment device, developed the substrate automatic loading and unloading module, the sample liquid addition module, the sample heating module and the spectrum detection module, and developed the automatic online monitoring of wastewater heavy metal based on laser breakdown spectroscopy. system.
The project has achieved innovative results in laser-induced plasma spectroscopy enhancement technology, wastewater heavy metal automatic enrichment method and data quantitative processing algorithm. The industrial wastewater discharge heavy metal online monitoring system was completed online in a wastewater smelting outlet of a smelting plant in Tongling. Automatic monitoring demonstration verification. The project completed the various assessment indicators specified in the contract, providing high-end technical equipment for the implementation of the comprehensive prevention and control plan for heavy metal pollution in Anhui Province and the State. The acceptance expert group unanimously agreed to pass the project acceptance.
