Below in conjunction with accompanying drawing, Vegetative Filter Strips purification simulation device of the present utility model is described in detail:
Shown in Figure 1, Vegetative Filter Strips purification simulation device of the present utility model comprises that inner filling has the soil box 100 of the soil body; For controlling the opertaing device 200 of indicator liquid in soil box, opertaing device 200 is connected with the interior balancing tank of soil box 100 by a fluid connection device; For regulating the conditioning equipment of the soil body gradient in soil box; And soil box support and opertaing device support.
Wherein, the flow of inlet water that opertaing device 200 is controlled in soil box 100, thus keep filter bag water velocity to be consistent within the same test period, for test controllability provides basic condition; Configure as required on the other hand the pollutant levels in opertaing device 200, thereby analyze the impact of different influent concentrations on Vegetative Filter Strips clean-up effect.
Particularly, the soil body in soil box 100 can be divided into two kinds: non-turbulent undisturbed soil and filling soil.Undisturbed soil has represented the native soil formation and physic-chemical property of research object preferably.Loading soil can be a kind of soil through screening, can be also several soil that mix by a certain percentage, although load soil, can not keep native soil structure, can be used for specializing in of certain object, and controllability is strong.For example, by changing the various parameters of soil (soil particle diameter, the pH value of the holard, or soil nutrient content etc.), study the affect situation of soil on different research contents.
In the present embodiment, can adopt undisturbed soil to be placed in soil box.If the soil body in soil box 100 is undisturbed soil, while loading the soil body, answer layering to load, every layer of suitable certain hour that stops carries out topsoil backfill again, to meet the requirement of undisturbed soil.
Preferably, soil box 100 comprises a plurality of for gathering the collection hole 105 of water sample, gathers the middle part that hole 105 is all arranged on soil box 100.By being arranged on the collection hole 105 at soil box 100 middle parts, can carry out the collection of water body example, can be used in the content analysis of soil moisture nutriment, thus the situation that affects that more different flow condition and influent concentration purify Vegetative Filter Strips.
Further, soil box 100 also comprises drainpipe 101, and drainpipe 101 is arranged on the either side of soil box 100 bottoms and end.Drainpipe 101 can, for regulating the hydrologic condition in soil box 100, meet different test demands.
Further, soil box 100 also comprises filter plant, and this filter plant 103 is arranged between the bottom and drainpipe 101 of the soil body.Filter plant 103 can be comprised of gauze and gauze, can regulate the hydrologic condition in soil box 100, and filter plant 103 requires there is good mistake water-based energy, can prevent again the seepage of particle.
Preferably, opertaing device 200 is distribution reservoir.The main material of distribution reservoir can be PVC(Polyvinylchloride), opertaing device 200 is used for controlling the interior flow condition of soil box 100 on the one hand, thereby guarantees that filter bag water velocity is consistent within the same test period; By changing different pollutant loads in the interior solution (allocating voluntarily according to content of the test) of distribution reservoir, can meet different testing requirementss on the other hand.
The size of distribution reservoir is according to size and the flow velocity designed, designed of different tests requirement, soil box, because part test requires liquid in distribution reservoir, it is nutrient solution, therefore the size of distribution reservoir should be taken into account interpolation time and the fluid preservation time of liquid in distribution reservoir, the flow velocity that can be set based on the test, calculates 2-4 hour trickle volume as the nominal volume of distribution reservoir.
It is good that the requirement planning sth. ahead according to different tests prepares nutrient solution concentration, nutrient solution is added in distribution reservoir, for guaranteeing nutrient solution quality, and consider the operability of test, control nutrient solution volume in distribution reservoir and meet test in 4 hours with interior, consider the impact of the factors such as evaporation of liquid in distribution reservoir, distribution reservoir should be added a cover.
Due to the environmental impact factor that Vegetative Filter Strips purification simulation device relates to more (flow velocity, vegetation, soil, water cut and the content of organic matter etc.), permutation and combination method is very complicated, the design of test needs to design on the analysis foundation of data in the wild, take Vegetative Filter Strips hydraulic detention time as example, as 900 seconds, different water velocities can be set.If consider that more multifactor will be more complicated.By Vegetative Filter Strips purification simulation device of the present utility model, can change the indexs of correlation such as flow of inlet water, water quality, vegetation and soil physical property of soil box, by detecting the chemical index situation of change of the soil body in Inlet and outlet water water quality and soil box, can reach the multifactor combined crosswise of multi-angle and analyze the situation that affects that many influence factors purify Vegetative Filter Strips, and then explore major influence factors and the controlling elements thereof affect Vegetative Filter Strips clean-up effect, for the research of Vegetative Filter Strips removal mechanisms at work, provide smoothly data basic.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
