Description
Technical field
The present invention relates to rapid evaluation of renovation effect of contaminated soil, specifically a kind of devices and methods therefor of rapid evaluation of renovation effect of contaminated soil.
Background technology
The evaluation of contaminated soil repairing effect is the key link [document 1: Zhou Qixing edits 2004 contaminated soils and repairs principle and method Beijing: Science Press] of soil environment pollution control.The simple chemical method that relies on is diagnosed, under many circumstances because of can not characterizing the total quality feature of soil environment comprehensive, scientifically, the time and cause some wrong conclusions.Soil environment pollution ecology toxicology diagnostic techniques is complied with this objective requirement, is also carried out rapidly thus.Physics, the chemistry and biology of migration, conversion and the degraded experience a series of complexity of pollutant in soil environment change.In these change, part pollutant is removed from system, but other pollutants are in form and change in nature, generate new intermediate product, they tend to bring bigger potential safety hazard [document 2: Sun Tiehang to system, Song Yu virtue .1999. soil environment PAHs and mineral oil phytoremediation study on regulation, Chinese Journal of Applied Ecology, 10:225-229; Document 3:Posthuma is in aneco-toxicological standard protocol with protozoa L.1997.Progress; Results form apilot ring-test with soil protozoa.Chemosphere, 35:1023-1041].Therefore, judge that with the minimizing of target contaminant the degree that soil is cleaned produces wrong result sometimes merely.Earthworm is the biological bridge that transmits of terrestrial organism and soil environment.After soil environment was by all kinds of Pollution by Chemicals, the contaminated soil environment will produce different adverse effects to existence, growth, the breeding of earthworm, even dead.Therefore, the situation of utilizing earthworm indication soil environment to pollute, estimate the important indicator [document 4: Song Yufang that soil environment quality has been used as the diagnosis of soil environment pollution ecology toxicity, Zhou Qixing, Song Xueying, the ecological toxicology diagnostic method progress that Sun Tie top gem of a girdle-pendant .2002. soil environment is polluted. ecological science 21 (2): 182-186].
Earthworm acute toxicity testing, long term toxicity test and avoidance experiment are from the toxicity of different test terminal point reflection chemical substances, wherein, the chemical substance of acute toxicity test reflection high concentration is the lethal effect of (14d) generation in a short time, chronic toxicity test reflection chemical substance is avoided the influence of experiment reflection chemical substance to the earthworm behavior to the inhibition of earthworm fertility.Estimate for the contaminated soil repairing effect, obviously, the earthworm acute toxicity testing that only limits to measure high concentration chemical substance toxicity is no longer suitable, the earthworm long term toxicity test reaction time long (56d), and need be to earthworm ovum and young counting, waste time and energy, by contrast, earthworm avoiding reaction easy (only 3d) fast, favorable reproducibility, highly sensitive [document 5: Bu Chunhong, the application progress of tall and big civilian .2006. earthworm avoiding reaction in ecological toxicological study. agricultural environment science journal .25:799-804].
The experimental provision of current utilization earthworm avoiding reaction adopts single box body [document 6: Tai Peidong usually, Li Peijun, permitted China. a kind of fast soil health quality diagnosing method and experimental provision of being used for. China: G01N33/24.2004.01.21], single box body is divided into two Room, cleaning soil and pollution soil are placed on two Room of box body, earthworm is gone in the box body by artificial input, fails to make full use of the autonomous selection avoidance ability of earthworm, and artificial subjective influence factor is bigger; Once can only experimentize to a kind of soil sample, repeated experiments and parallel laboratory test need be carried out in other box, because the conditions such as moisture illumination in the different boxes are difficult to keep the repeated variation that causes in full accord; Earthworm can only be moved at the bottom of box body two Room, and the possibility that moves freely reduces; The humidity of soil is unadjustable in the slot to avoid.
Summary of the invention
The object of the present invention is to provide and a kind ofly utilize earthworm obviation principle fast to the evaluating apparatus and the method thereof of contaminated soil repairing effect.
For achieving the above object, the technical solution used in the present invention is:
The device of estimating avoids the chamber by earthworm and moisture adjustment disk is formed, and earthworm avoidance chamber places and is provided with gauze on the moisture adjustment disk between the two, avoids the indoor coaxial central locellus that is provided with earthworm, is provided with light source in it; Earthworm is avoided the chamber and is provided with baffle plate with space between the central locellus, is separated into a plurality of earthworms that fill cleaning soils respectively and pollute soil and avoids locellus, and each earthworm is avoided locellus and is provided with shadow shield, on the baffle plate and central locellus have earthworm escape hole all around; Avoid the bottom, chamber earthworm and have the moisture adjustment hole.
Earthworm is avoided the chamber and is provided with a plurality of barrier partitions with space between the central locellus and becomes a plurality of earthworms to avoid locellus, and adjacent earthworm is avoided locellus and fills cleaning soil respectively and pollute native.
Described central authorities divide the indoor dividing plate that is provided with shutoff earthworm escape hole.
Described earthworm is avoided chamber size less than moisture adjustment disk.
The using method of evaluating apparatus: in moisture adjustment disk, fill up colored mud, add water to state of saturation; To clean soil and pollute soil and be divided in successively, the a plurality of earthworms avoidances that space between earthworm avoidance chamber 1 and the central locellus 3 are separated into by baffle plate 4 divide indoor, and the earthworm chamber of avoidance lain in a horizontal plane on the moisture adjustment disk, and keep water cut to regulate the water cut of flower mud in the pallet, make earthworm avoid indoor soil and reach suitable water holding capacity; Earthworm being placed on central authorities divides indoor again, utilize central locellus inner light source that earthworm is carried out illumination, hide each earthworm with shadow shield simultaneously and avoid on the locellus, treat to place 25 ± 1 ℃ of constant temperature stationary indoors to place 72 hours in device after earthworm all changes in the soil, then use the earthworm escape hole on the dividing plate shutoff central authorities locellus, detect each and avoid the indoor earthworm quantity of branch.
The advantage that the present invention had:
1. ability is avoided in the autonomous selection that makes full use of earthworm.Earthworm of the present invention directly is not added in the middle of the soil, but puts into the middle locellus of device, and middle locellus is carried out illumination, to the avoidant property of light autonomous selection of earthworm is entered in the different soil by earthworm.
2. experimental provision of the present invention can be measured a plurality of pedotheques simultaneously, and the plug by dividing plate with holes, realizes once the mensuration to a plurality of pedotheques or different soils sample.
3. earthworm can be divided indoor free activity in a plurality of avoidances, and the present invention on average is provided with the escape hole of 20 diameter 1.5cm on the baffle plate of different locellus, and the escape hole total area accounts for 40% of dividing plate area.Earthworm can move freely in each avoids the different aspects of locellus.
4. experimental provision of the present invention is provided with water cut and regulates pallet, is covered with the high colored mud of 5cm in the pallet, and by the humidity that pedotheque is regulated in the adjusting of flower mud humidity, and the humidity unanimity of pedotheque is respectively tested in maintenance.
5. experimental provision volume of the present invention is little, is easy to carry, and is fit to field evaluation.
