Description
Technical field
A kind of dystopy multichannel Mercury in Soil flux rapid measurement device is the utility model is related to, belongs to the measurement skill of Mercury in Soil
Art field.
Background technology
Soil is the basis of agricultural production, however as the fast development of China's economy, the pollutant containing heavy metal, especially
It is that mercury metal enters soil by all means, has gradually formed heavy metal pollution of soil, heavy metal pollution of soil is polluted because of it
Concealment, chronicity and irreversibility and by World Focusing, its not only degenerated soil fertility, reduce crop product and product
Matter, and pollution of agricultural products and water resource pollution can be triggered, and the life and health of the mankind is endangered by food chain.
Reparation for Soil Mercury Pollution has become the hot spot in current environment scientific and engineering field, dirty to Mercury in Soil
Before dye is administered, measurement soil mercury content is generally required, but existing measurement method mainly measures at the scene, or by soil
Independent measurement after earth collection, measurement error big the problems such as low there are measurement efficiency.
Mercury is one of most strong heavy metal contamination thing of bio-toxicity, and it is big that its murder by poisoning to human body is mainly manifested in damage
Brain.In past more than 100 years, air mercury content adds 3 times.Soil, deposit, lake and the river of global large area, by
Produce in the unreasonable mode of the mankind, use and store mercury and be subject to serious mercury pollution.China is that the discharge of global mercury is big
State, while be also one of mercury pollution country the most serious.The research of mining soil mercury flux monitoring, to mercury contaminated soil reparation
Research and development and the soil pollution integrated control of mercury ore area of technology etc. have great importance.
Due to long-term exploitation and smelting, mercury content is up to 29.6-793mg/kg in Guizhou wanshan mercury area agricultural land soil,
Decades of times beyond national Soil standard is to thousands of times.According to incompletely statistics, the area of Guizhou Mercury Mine's area's mercury contaminated soil has surpassed
Cross 69000 hectares.Mercury content is 120-1150ug/kg in mercury ore area crops, and 115 are up to beyond national food hygienic standard
Times.Correlative study shows that the mercury in vegetables is mainly derived from air.Existing mercury ore exploitation and smelting have stopped, and high Mercury In The Air contains
Amount is volatilized essentially from serious mercury contaminated soil.Previously there is scholar to study the flux for finding that mercury mining soil discharges mercury into air
Average value ranges are 162-8385ng/ (m2H), it is higher by 1-3 order of magnitude of background area.It can be seen that this area suffers from serious air
Mercury pollution.Therefore, while being administered to Soil Mercury Pollution, mercury should be avoided to be volatized into air from soil, causes two
Secondary pollution.At this time, it may be necessary to observe the volatilization flux of Mercury in Soil.But existing measurement method mainly field survey at the scene, and
This measurement method needs to transport complicated instrument and its supporting equipment；Environmental condition at the same time（Wind speed, temperature and illumination etc.）
Real-time change, easily influences Mercury in Soil volatilization, and multigroup Mercury in Soil flux can not be measured at the same time.
In summary：A kind of efficient, quick, accurate and multichannel Mercury in Soil flux measuring device is established, it is dirty to following mercury
The research and development and the soil pollution integrated control of mercury ore area of dye soil restoring technology, which all have, to be of great significance.
Utility model content
The technical problems to be solved in the utility model is：A kind of dystopy multichannel Mercury in Soil flux is provided and quickly measures dress
Put, have simple in structure, easy to operate, measurement efficiency is high, the advantages that sample amount is few, result is accurate is needed, to overcome the prior art
Deficiency.
The technical solution of the utility model：A kind of dystopy multichannel Mercury in Soil flux rapid measurement device, including mercury vapour
Analyzer and multi-channel sampling device, the channel outlet of multi-channel sampling device pass through out sample tube and the port input of mercury vapour analyzer
Connection, the channel entrance of the multi-channel sampling device pass through sample feeding pipe and the high borosilicate flux bottle top for holding soil to be measured
Connection, in sample feeding pipe（Sample introduction pipe end）On be provided with aspiration pump.
Flowmeter is provided with the sample feeding pipe.
The flowmeter is arranged between aspiration pump and high borosilicate flux bottle.
The multiple sample feeding pipes being wherein arranged side by side are connected by Teflon threeway with aspiration pump, can so pass through same pumping
Air pump realizes the pumping of multiple sample feeding pipes, and realization measures at the same time.
The internal diameter 15cm, height 20cm of the high borosilicate flux bottle；Away from bottom 3cm be inserted into respectively two it is symmetrical a length of
2cm, internal diameter is 0.5cm tubules, as air inlet；The lid of flux bottle is frosted mouth, and cap top inserts a tubule and is used as
Gas port.
The beneficial effects of the utility model are：Compared with prior art, the utility model can be successively（At the same time）To multigroup soil
Earth mercury flux is quickly measured, it is possible to increase the measurement efficiency of Mercury in Soil.In addition, this measurement method can exclude external ring
Influence of the border to measurement result, has the characteristics that measurement result is accurate, needs sample amount few etc., easy at the same time to multigroup measurement result
Analysis contrast.
