Description
Technical field
The utility model is related to a kind of continuous water dispensing apparatus for column experiments, belongs to water-treatment technology field.
Background technology
Pollutant removal behavior and efficiency evaluation process are the key problems in the research of field of environment engineering water technology.
In the research of pollutant removal degradation experiment, two kinds of commonly used implementations are static experiment and dynamic experiment：It is static real
I.e. common batch experiment is tested, test solution and decontamination material containing target contaminant are added in specific reaction vessel, one
Reacted, be analyzed and evaluated by the way that different time after reaction is measured by sampling under fixed shaking, temperature, air pressure conditions；Dynamic
Experiment is the column experiments of continuum micromeehanics, and generally decontamination material is filled in experiment post, then will be molten for trying containing pollutant
Liquid is injected into experiment post, is measured by sampling and is analyzed and evaluated at column outlet.Compared with static experiment, dynamic column experiments have
Higher scientific research value and practical engineering value.Packed column, can be in laboratory according to filler and the difference of design condition
In interior simulation soil or underground water hydrologic regime and the transportion and transformation of target contaminant, it is particularly possible to simulate prolonged permeation
Property reaction wall (PRB) Evolution, and these to be static experiment can not realize.In addition, compared with static embodiment,
Dynamic column experiments also have more significant advantage in terms of plant area space, Operation and Maintenance, system stability.
Water dispensing apparatus when laboratory carries out column experiments is usually 5-50L glass jar, holds and is matched somebody with somebody with pure water in glass jar
The solution of system, then by supplying solution in the continuous post to experiment of the modes such as siphon.Therefore, when experiment bed volume is larger, flow velocity
During larger or longer experiment period of supervision, there is problems with the water dispensing apparatus：(1) have because glass jar holds amount of solution
Limit, does not reach experiment demand, thus manually must repeatedly prepare solution and supplement is periodically filled into glass jar, therefore,
Glass jar feed flow automaticity is relatively low, continuity is poor, cumbersome, hence it is evident that to increase workload；(2) for preparing every time is molten
Because there is error and disunity in liquid concentration, feed flow concentration is unstable, have a strong impact on the accuracy of experimental result；(3) glass
Solution in tank is with the progress of column experiments, and liquid level declines, and glass jar changes to the flow velocity and pressure of experiment post feed flow, supplies
The less stable of liquid；(4) into glass jar fill make-up solution time easily normally worked with experimenter, rest when
Between conflict and bring inconvenience.It is general and current commercial commercial high precision micro diluter and industrial on-line dilution installation cost are high
Logical laboratory is difficult to bear, and its working dilution capacity is not suitable for the column experiments of usual laboratory scale yet.
Chinese utility model, publication number：203461868U, publication date：On March 5th, 2014, disclosing a kind of simulation can ooze
The laboratory experiment system of permeability reaction wall, including be sequentially connected feed flow bag, with flow control water inlet pipe, simulate it is permeable
Property reaction wall experiment column device, waste collection bucket, absorbent packet.Experiment column device composition includes：Permeable reaction post, gravel
Stone bed course, sand gravel protective layer and cylindrical shell.Sand-gravel cushion, permeable reaction post, sand gravel protective layer from lower and
On be arranged in cylindrical shell, the bottom of cylindrical shell offers water inlet, and top offers delivery port, and side wall, which is offered, to be taken
Sampling plug is connected on sample mouthful, sample tap.The device measures permeable reactive barrier to 1,2- in underground water bis- by sample mode
The dechlorination effect of chlorobenzene, while examining the time of break-through of permeable reactive barrier.Its weak point is：(1) feed flow bag finite capacity,
Need periodically to change, therefore add experimenter's workload；(2) the solution concentration value in feed flow bag is certain, it is impossible to root
Factually testing needs to adjust into Mobile state, thus, feed flow bag feed flow applicability is poor；(3) pressure of feed flow bag feed flow and flow meeting
Change with the change of surplus solution amount in feed flow bag, therefore, it is difficult to ensure the stability of experiment condition.

The present apparatus port of export is connected with experiment column inlet, and experiment bed volume (BV) is 0.5L, and design object is to pass through
Continuous water dispensing apparatus carries out High Concentration of Arsenic solution and running water to mix the continuous micro- pollution of simulation for preparing As concentration for 50 μ g/L
Water, with 20BV/h (10L/h) constant flow rate by testing post.The built-in 50mL concentration of syringe 7 concentrates for 500mg/L As
Liquid, during the present apparatus is run, water distribution As concentration is measured by sampling by valve 15 in interval certain volume, to investigate the operation of the present apparatus
Stability, As concentration is analyzed using AFS, and analysis result is as shown in Fig. 2 the bright present apparatus of the chart is continuously run
During 4200L (8400BV undergoes 420h), the As concentration continuous-stable of water distribution has reached experimental design in 50-52 μ g/L
The requirement of target, embodies the good stability of the present apparatus.In addition, the present apparatus can provide 240L pollutants containing prescribed concentration daily
Water distribution be used to test the continuous supply of post, the working strength of traditional filling manner of formulation is significantly reduced, operation 420h's
In time, the present apparatus only needs repeatedly to change the medical plastic syringe 7 (50mL) for being filled with High Concentration of Arsenic concentrate, and nothing
Other operations are needed, thus the automaticity of the present apparatus is higher.In addition, required accessory is common commercial standard product, price
Cheap easy acquisition, its cost is far below commercially available commercial High Precision Automatic diluter and industrial on-line dilution device.It is common commercially available
