Description
Technical field
The utility model relates to the open-air enriching apparatus of underground water semi-volatile organic matter.
Background technology
Because the unreasonable disposal of " three wastes ", the unreasonable abuse of chemicals such as agricultural chemicals, chemical fertilizer, it is more and more serious to cause in the underground water semi-volatile organic matter to pollute, human survival and health are constituted a serious threat, thereby understand in time that the semi-volatile organic matter pollution situation has become instant problem in the underground water.Carry out at present that the research and appraisal for semi-volatile organic matter are wherein important ingredients in the nationwide groundwater contamination research and appraisal work, semi-volatile organic matter belongs to contaminant trace species, content in underground water is generally μ g/l or even ng/l rank, must adopt high sensitivity and specific analytical approach could detect its content in underground water, and the enrichment of semi-volatile organic matter is as the preprocessing process that detects, and is significant to follow-up extraction, testing.Current comparatively ripe method is open-air sampling, be transported to the laboratory at a distance, carry out pre-treatment and gas chromatography-mass spectrum monitoring analysis then, idiographic flow is: use 1 liter of Brown Glass Brown glass bottles and jars only sampling of handling through high temperature purification in the open air, must adopt sampler adjusting pressure to reach 0.2～0.25MPa in case the underground water degassing, rising pipe is slowly carried until water sample at the following 3cm of liquid level and being overflowed during sampling, cover bottle cap more rapidly and guarantee do not have air in the bottle, preserve at insulation can low temperature sampling back, long-distancely then carries out monitoring analysis after transporting the laboratory to.
Find that by the long-term work practice above-mentioned flow process has following problem: 1. because sampling bottle is that vial is frangible, in preservation, transportation, must resample as if after fragmentation occurring; 2. since from project district field condition to often far away the laboratory, sampling will keep low temperature, will prevent the sampling bottle fragmentation simultaneously, thereby causes low temperature storage and transport cost height; 3. for guaranteeing the sampling pressure requirement, should regulate pressure cost great effort and time, very easily damage water pump again, feasible sampling flow process complexity; 4. operation steps requires loaded down with trivial details, easily cause the analytical test result than mistake, the glass sampling bottle must be resampled if enter air, cause groundwater resource, sampling time and waste of electric energy, this problem in arid, that semiarid northwest lacks the area is particularly outstanding; 5. vial on-site sampling, Solid-Phase Extraction is carried out in long-distance transportation to the laboratory then, and the problem of this sampling flowsheet maximum is to cause loss and the phreatic secondary pollution of object in the underground water, has a strong impact on the recovery and test result.
The utility model content
At the deficiency of semi-volatile organic matter Sampling techniques in the existing underground water, the utility model provides semi-volatile organic matter enriching apparatus in a kind of underground water, to be implemented under the groundwater contamination investigation field condition enrichment to semi-volatile organic matter in the underground water.
For realizing the utility model purpose, this underground water semi-volatile organic matter enriching apparatus is characterized in that it comprises that one is provided with the cylindrical shell of overflow vent and evacuation port, the cylindrical shell upper end is provided with the water sample entrance, the water sample inlet end was equipped with hydrophone, be evenly equipped with connecting link on the cylindrical shell, install a disk body that is provided with water inlet pipe on the connecting link, one arm is set on the described water inlet pipe, sealing ring under water inlet pipe passes disk body and is located at disk body communicates, cross the lower end outlet of hydrophone and communicate with refluence pipe on being fixed on cylindrical shell, the lower end of refluence pipe exports the bottom that is positioned at cylindrical shell.
The technical progress that the utility model is obtained:
Because semi-volatile organic matter enriching apparatus in the underground water of employing the utility model structure, can realize under the Field Geology Investigations condition enrichment to semi-volatile organic matter in the underground water, eliminated existing use breakaway glass sampling bottle flow process, strengthened the operability of sampling process, the column of utilizing field condition to have adsorption film is crossed the tubulose of hydrophone or filling sorbing material and is crossed the sample mode that hydrophone has replaced existing glass sample bottle, greatly reduce the sampling cost, improved work efficiency, be implemented in compatible multiple underground water well type in the field condition sampling, spring and various sampling pump, both can be connected with deep well submerged pump, also can unite use with the shallow well centrifugal pump, satisfying under the above-mentioned positive pressure, can also be connected with vacuum pump, the sampling of realization negative pressure, be used for gathering surface water, spring, underground water overflows the sampling under the hydrogeological conditions such as band, so the utility model just, the characteristic of negative pressure sampling has satisfied the collection service condition under the various field conditions substantially.The utility model all adopts 316 type stainless steels to make, and easily preserves, and is easy to carry, anti-organic corrosion, and no organic contamination deposits yields has avoided the external source of sampling process to pollute, and is convenient to the geologic examination use under the condition in the open air.The utility model can directly be connected with sampling pump or sampler, and the underground water sample can directly contact with the present invention, has reduced the artificial link that participates in such as vial sampling, sealing, has avoided artificial contact factor, does not produce secondary pollution.Reduced the vial sampling, the glass sampling jar transports, opens flow processs such as glass sampling jar Solid-Phase Extraction at a distance, avoided the loss of semi-volatile organic matter in the aforesaid operations flow process, improved the recovery of semi-volatile organic matter, to add the standard specimen phenanthrene in the underground water be example to detect, the utility model recovery can rise to 90% by 70% of prior art, the utility model be particularly useful for the groundwater contamination research and appraisal and repair in the research in the open air fast, accurate enrichment underground water semi-volatile organic matter.
