Technical field
The utility model relates to a kind of experimental provision, relates in particular to a kind of experimental provision of measuring ion coefficient of diffusion in soil.
Background technology
Ion coefficient of diffusion in soil is migrate in the soil key parameter of diffusion of pre-measured ion, and the accurately pre-measured ion basis of refuse landfill design and contaminated soil improvement etc. especially that in soil, distributes.Generally test this parameter now by the earth pillar diffusion experiment.Because experimental provision is an one-piece construction, thus need earlier soil sample to be made, and then move in the earth pillar diffuser casing.This contacts undertighten around just having caused soil sample and diffuser casing container, contaminated ion easily from around diffusion downwards, thereby influence measuring accuracy.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, guarantees the experimental provision of mensuration ion coefficient of diffusion in soil of measuring accuracy.
The utility model comprises pollution source solution chamber, soil sample chamber and leaches solution chamber, and described soil sample chamber is arranged in pollution source solution chamber and leaches between the solution chamber, removably with pollution source solution chamber with leach solution chamber and be tightly connected; In above-mentioned pollution source solution chamber, a pollution source solution chamber is set and gets a liquid mouth and a pollution source solution chamber fluid mouth, be provided with one in the solution chamber and leach solution chamber and get liquid mouth and and leach solution chamber's fluid mouth above-mentioned leaching.
When the experimental provision in use the utility model experimentizes, the contaminated ion of the prescribed concentration of in pollution source solution chamber, packing into, the distilled water of in leaching solution chamber, packing into.Get the liquid mouth and leach solution chamber by above-mentioned pollution source solution chamber and get the liquid mouth and take out solution in the corresponding solution chamber, to measure pollution source solution chamber and to leach in the solution chamber contaminated ion concentration over time.Test the soil sample in the specimen chamber that fetches earth after finishing, the ion concentration of diverse location in the test soil sample.This ion concentration can be represented with Fick law (Fick ' sLaw) or macroscopical polyion migration diffusion diffusion equation, and by inverse analysis method, try to achieve the effective diffusion cofficient of ion in soil sample.When pollution source solution chamber with leach liquid level in the solution chamber when contour, be pure diffusion experiment; When pollution source solution chamber with leach liquid level in the solution chamber when not contour, be the convection current diffusion experiment.
This experimental provision is simple in structure.The soil sample chamber can and leach solution chamber from pollution source solution chamber and disassemble, thereby can directly soil sample closely be compressed in the soil sample chamber, closely contact between making around soil sample and the soil sample chamber, efficiently solve contaminated ion around around diffusion problem, to guarantee measuring accuracy.
Preferably, described soil sample chamber is tubular; On the sidewall of described pollution source solution chamber, a pollution source solution chamber joint is set, on the described sidewall that leaches solution chamber, is provided with one and leaches solution chamber's joint; One end of described soil sample chamber interconnects by ring flange and Tetrafluoro spacer and pollution source solution chamber joint, the other end of described soil sample chamber by other ring flange and other Tetrafluoro spacer with leach solution chamber's joint and interconnect.
Adopt the syndeton of ring flange and Tetrafluoro spacer simple, make things convenient for the dismounting of soil sample chamber, and avoided the joint infiltration effectively.
Preferably, in above-mentioned pollution source solution chamber, a pollution source solution chamber is set and connects the pressure mouth, be provided with one in the solution chamber and leach solution chamber and connect the pressure mouth above-mentioned leaching.
The above-mentioned pressure mouth that connects can be convenient to pressurize in corresponding solution chamber in experimentation, to guarantee carrying out smoothly of convection current diffusion experiment.
Preferably, described pollution source solution chamber, to leach solution chamber, soil sample chamber and ring flange all be to be made by the PVC material.
Adopt the critical piece of this experimental provision of PVC material, have and draw materials easily advantage easy to make, with low cost.
