Description
Technical field
The invention belongs to monitoring water environment technical field, specifically, relate to a kind of micro-disturbance passive type underground water sampler.
Background technology
In groundwater environment pollution surveys, can the representative groundwater sample of Obtaining Accurate be whether the pith of groundwater environment pollution surveys information evaluation.The developed countries such as America and Europe in groundwater sampling technical research comparatively early, have very strong research and development ability, and China has also successively carried out the research work of Sampling techniques equipment.Present stage, representative underground water sampler had: Bailer sampler, discontinuous interval sampler, air pocket pump, gas displacement type sampling thief, inertia lift pump etc.Structure, Bailer sampler can be divided into bivalve Bailer sampler and single valve Bailer sampler, bivalve Bailer sampler all has a non-return valve in bottom and top, equal can put into groundwater monitoring well similar to single valve Bailer sampler is used to carry out groundwater sample sampling work, but need use artificial releasing means valve open after using Bailer sampler, again the groundwater sample taken out is loaded sampling bottle, increase the duration of contact with air.Air pocket pump is that water inlet and freeing port are separately installed with non-return valve at a steel cylinder built with a pliable and tough squeezable air bag, when air pocket pump being put into monitoring well water, under the effect of hydrostatic force, water enters the pump housing by the non-return valve in bottom, when air pocket pump is full of, and closure of check ring.Enter the space between the pump housing and gasbag ektexine at earth's surface injecting gas, extruding gasbag makes waterbornely to be raised to pipeline, at the non-return valve at top, the water entering pipeline can not be refluxed, release gas balloon water-filling again.Repeat in the same way, groundwater abstraction, in whole extraction process, water sample contacts with pipeline, is also not easy to cleaning simultaneously.
No matter be single valve or bivalve Bailer sampler all can increase air and sample contact in sampling process, cause the Cucumber loss of sample or change the character of sample, being difficult to obtain representative groundwater sample.Compare bailer sampler, other sampler have self feature separately, be applicable to the sampling of different characteristic pollutant, but their sampling utility appliance are more, safeguard and cleaning complicated, cause cost to increase or feasibility declines.Therefore, design one can the true underground water water sample of Obtaining Accurate, and the sampling apparatus with stronger operability low cost is very necessary.
