Description
Technical field
The present invention relates to heavy metal wastewater thereby on-line monitoring field, more particularly, to a kind of sewage based on XRF technology
Heavy metal on-line monitoring equipment.
Background technology
In recent years, domestic a lot of particularly serious heavy metal pollution events have been recurred.In January, 2012, Guangxi Longjiang river is sent out
Raw cadmium pollution event, the serious drinking water safety threatening Liuzhou City 1,440,000 people.With《Heavy metal pollution integrated control " 12
Five " plan》Enforcement, China's heavy metal analysis will increase with the monitoring instrument market demand.Water body is the important of heavy metal pollution
Carrier, all contains heavy metal in the enterprise wastewater of the industry such as many electric power, battery, metallurgy, is the significant concern point of environmental monitoring
One of.In terms of environmental pollution, heavy metal refers to the significant heavy metal of bio-toxicity such as hydrargyrum, cadmium, lead and " metalloid "-arsenic.
What human body was poisoned with maximum has 5 kinds：Lead, hydrargyrum, arsenic, cadmium.These heavy metals can not be decomposed in water, and people drinks rear toxicity puts
Greatly, be combined with other toxin in water and generate the bigger Organic substance of toxicity.
Based on above reason, country requires increasingly stricter, to a huge sum of money to the heavy metals emission standard in factory's sewer
The required precision of on-line monitoring equipment belonging to waste water is also more and more stricter.But at present in the on-line monitoring of heavy metal wastewater thereby
Field market share highest is still traditional chemical colorimetry, and the method has following defect：
1) add pharmacy response and colour developing medicament before testing, shelter medicament etc., made by the various medicaments adding
Water sample colour developing to be measured, is converted to the content of heavy metal in water, belongs to indirect monitoring, and add according to the difference of the colour developing depth
Various medicaments can exclude with waste liquid, secondary pollution is caused to environment；2) because the limitation of its Cleaning Principle, testing result
Can be affected by factors such as the particulate matter in tested water, colourity and other elements, generally require certain pre-treatment step and enter
Row filtering type samples, and the accuracy of such data and representativeness cannot ensure；3) due to needing the reaction that each is added
Medicament carries out accurate quantification, is often caused detection error because the quantitation of some medicaments is forbidden, the stability of detection data
Cannot ensure；4) because each sampling quantity is few, sampling interval duration is long, and detection data may not have representativeness and real-time.
The requirement to factory's sewer for the country at present is more and more stricter, but the traditional change of existing market occupation rate highest
Learn colorimetry and because adding various reaction reagents, environment is caused with secondary pollution while detection, and because its principle
Limitation testing result can the factor such as particulate matter colourity in tested water and other elements impact, generally require certain
Pre-treatment step and need the pharmacy response that each adds is carried out accurate quantification, the accuracy of data cannot ensure,
Sampling quantity minority is not according to may have representativeness and real-time.
Chinese invention patent, publication number：CN103105407A, publication number：2013.05.15, disclose a kind of mensure liquid
In sample, the method for the content of heavy metal, comprises the following steps：Using polymeric membrane, described fluid sample is filtered, described
Polymeric membrane is impermeable for described heavy metal, so that the heavy metal in described fluid sample is trapped within described high score
On sub- film, and obtain the polymeric membrane of attachment heavy metal；Using the high score to described attachment heavy metal for the Xray fluorescence spectrometer
Sub- film is detected, to obtain X-ray fluorescence spectra data；And it is based on described X-ray fluorescence spectra data, determine described
The content of heavy metal in fluid sample.Effectively the heavy metal in fluid sample can be measured using the method.It is not
It is in place of foot：This patent is unable to direct detection heavy metal in waste water content, needs enrichment on polymeric membrane before testing,
Complex structure, and need polymeric membrane no block and other exceptions in the case of use, strict to water quality requirement to be checked, deposit
In unreliable factor.
