Description
Technical field
The present invention relates to a kind of dedicated well-flushing sampling pump of Techniques of Underground Water Environment Monitoring Well and well-flushing sampling methods, are used for underground water
The well-flushing and sampling work of monitoring well, belong to Techniques of Underground Water Environment Monitoring Well equipment technical field.
Background technique
With Chinese society expanding economy, groundwater environment problem becomes increasingly conspicuous, and partial region underground water is by tight
Heavily contaminated.The accurate investigation of science, evaluation is carried out to contaminated underground water to become more and more important with improvement.Underground at present
Water pollution survey, water quality monitoring main means be to take sample to be chemically examined in groundwater monitoring well.It is taken carrying out underground water
When sample works, the whether abundant well-flushing of Techniques of Underground Water Environment Monitoring Well and the selection etc. for sampling utensil are all directly related to underground
The quality and validity of water water quality detection result.Developed countries attach great importance to groundwater sampling technology, formed scale,
The sampling appliance product of systematization；And China starts late in terms of groundwater sampling technology especially sample devices, technology phase
To lagging behind foreign countries.
Well-flushing refers to due to requirement of engineering, during workover treatment, by well-flushing medium by pumping-in equipment through pit shaft or brill
Bar injection, carries the substance (liquid phase, solid phase, gas phase) in pit shaft to ground, so that the medium character changed in pit shaft reaches
The process of job requirements, it is main comprising changing slurry, well-flushing and three continuous operations of drawing water.
Through market survey, China's sampling utensil common at present is roughly divided into four classes: sampling cartridge type sampler, inertia-type are adopted
Sample device, gas-powered formula sampler and diving, Electric pump type sampler.Each utensil performance superiority and inferiority is irregular, at a low price pump such as inertia
Formula sampler and immersible pump etc., bore flow is big, sampling quality is low, it is difficult to meet increasingly strict clean sampling requirement；And it can
With meet the requirements air pocket pump and U-tube pump etc., need to carry the equipment such as operation bench and operation it is more complex it is cumbersome, efficiency is lower,
There are service lifes it is short, consumptive material is expensive the problems such as.
When Techniques of Underground Water Environment Monitoring Well shaft building, sediment content is higher, so more stringent to well-flushing job requirement, well-flushing is extremely
Water sand removal is net, at least needs to clean 3~5 times of (about 50~500m of water body in well casing3Underground water volume).And current state
It is immersible pump that interior market well-flushing, which commonly pumps, but it is often due to diameter cannot function as greatly well-flushing and sampling instrument, or exist
The devices such as generator and external power supply, use cumbersome；Then efficiency is extremely low, time-consuming and laborious for artificial Beile's pipe water lift；Though there is portion
The available uses such as point air pocket pump, minor diameter Multifunction centrifugal pump, but there are expensive, day-to-day loss is very big, flow velocity is low
Defect sample at high cost so that well-flushing inefficient.
China has promulgated the shaft building specification of multinomial Techniques of Underground Water Environment Monitoring Well and the technical method of sampling successively at present, wherein
Regulation monitoring well well casing outer diameter scope of design is 50~200 mm, and depth to water range is in groundwater monitoring well under normal circumstances
2~100 m.Well-flushing should be carried out before acquisition water sample in time, cleaning underground water consumption must not be less than 3~5 times of well volume (well-flushing waters
About 10~100 m3).And immersible pump is often due to diameter is big, greater than the hole diameter of part monitoring well, restricted application；Portion
Point air bag flow rate pump is smaller, efficiency is lower and expensive, cost performance is not high；Then efficiency is extremely low for artificial Beile's pipe water lift well-flushing,
Need to expend a large amount of manpower and material resources.
Monitoring index in " the groundwater quality standard GB/T-14848-2017 " that China came into effect on May 1st, 2018
By 39 indexs of primary standard are increased to 93, wherein organic compound index increases 47, also increases and adopts to underground water
The requirement of sampling instrument and method: while reducing the disturbance to underground water to the greatest extent, it is desirable that sampling flow velocity preferably less than 0.5 L/
min.When having carried out press proof sampling, low-cost diving pump discharge is big, larger to the disturbance of underground water, is not suitable for volatilizing
The sampling of the organic pollutants such as property, half volatile；Air pocket pump price is high, and the silt in underground water is big to the loss of air pocket pump, property
Valence ratio is not high, and popularization degree is low；Either immersible pump or air pocket pump require the devices such as generator or external power supply, Fan Zachen
It is heavy, not portable, cause sampling efficiency low.
For the sampling pump of underground water, at present mainly include the following types: Chinese patent CN207866560U " groundwater sampling
Device " can prevent the full rear directly suck-back of the water in receiving flask from entering in sampling pump, protect sampling pump by the way that transition bottle is arranged, the
One solenoid valve can stop outside air to enter in transition bottle, and sampling pump is avoided to vacuumize again, and second solenoid valve can be avoided
Humid air enters sampling pump, extends the service life of sampling pump, reduces cost.But it is primarily adapted for use in sampling, then for well-flushing
Low efficiency.Chinese patent CN203587386U " built-in inertia underground water sampling pump " by probe tube and is placed in the probe tube
Interior water baffle ring, ball sealing and the base combination crossed is constituted, and solves that external inertia underground water sampling pump outer diameter is big, globality is poor
The problems such as with abrasion well casing.But the devices such as external power supply are needed, use is cumbersome, time-consuming and laborious.Chinese patent
CN205506471U " a kind of hand-held sampler ", by main casing internal cavities be equipped with control unit, built-in motor and
Built-in sampling pump can hold manual sampling, can also place and sample with automatic on the ground, be automatically stopped, the scene of facilitating is adopted
Sample work, but it is used for well-flushing work then low efficiency.
" a kind of Novel underground monitoring water environment well is special by the utility model patent ZL 2,018 2 0339278.5 of the applicant
With well-flushing sampling pump " solve some problems, but there are the following problems: 1, automatically taking water is realized using water level sensor and stopped
Only, sampling pump leaves after the water surface that there are still the idle periods；2, battery box structure is unreasonable, and battery and the pump housing are closed entirety, no
Battery can be replaced, wiring is complicated；3, pump capacity is non-adjustable, poor operability；4, water pump diaphragm material has an impact to water quality, deposits
In secondary pollution.
