Abstract
The utility model provides a pair of keep apart and control sour side slope ecological recovery structure, this structure mainly includes lime layer, bentonite layer, plants soil layer, nutrition substrate and plants the plant at planting soil layer, lime layer is laid at acid treatment area side slope surface, lays bentonite layer on the lime layer, lays on the bentonite layer and plants the loam layer, lays nutrition substrate on planting the loam layer. This structure can effectually realize vegetation and cover green, reaches the ecological restoration effect that the arbor and shrub grass combined together, through the isolation measure, can effectually prevent to administer regional deep acid water exosmosis, has both solved ecological restoration back acid water pollution problem, provides a good growing environment again for the vegetation restoration, is favorable to vegetation.
Description
Technical Field
The utility model relates to an ecological technical field that resumes in acid region, like copper mine refuse dump, dump leaching yard, stope etc. gangue stope, barren rock field etc. the ecological structure that resumes of sour side slope of isolation accuse of a concretely design.
Background
Mining of mine often is along with elemental sulphur, and elemental sulphur can produce the acid after the oxidation, and serious polluted environment is especially serious in this kind of condition of copper ore, coal gangue ore, and along with the national attention to the environmental protection, these mines also corresponding ecological remediation, the main problem that exists at present includes:
(1) the acidity cannot be effectively controlled
At present, most of the ecological restoration measures adopted in China are earthing or neutralization by adding alkaline materials of lime, the measures only have certain effect on the surface layer, and the surface of the soil also has the phenomenon of acid reversion along with acidification of deep rocks after a long time.
(2) Can not realize sewage disposal and diversion
Because the surface layer is easy to generate the acid reversion condition, the initial rainwater after ecological restoration is polluted, and the initial rainwater needs to be collected and treated, so that the standard of ecological reclamation is difficult to achieve, and the initial rainwater in a treatment area after ecological restoration cannot be treated according to clean water.
(3) The environment for plant growth is degraded
The traditional method does not improve the growing environment of plants, the whole area is also in an acid environment, and the risk of degradation of the ecological system exists after the growth time.
Based on the above problems, measures such as covering soil in an acidic region or neutralizing an alkaline material added with lime have a certain effect on the surface layer, and how to control the acid is the key to success or failure of ecological restoration.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, an object of the utility model is to provide an keep apart sour slope ecological recovery structure of accuse, mainly used acid regional copper ore refuse dump, dump leaching field, stope etc. gangue stope, spoil area through set up a recovery structural layer on the regional slope surface of mine site acid, realize needing to administer regional acid improvement and plant the plant.
In order to achieve the above object, the present invention provides a method for manufacturing a semiconductor device, comprising:
the utility model provides an keep apart sour side slope ecological restoration structure which characterized in that, includes lime layer, bentonite layer, plants soil layer, nutrition substrate and plants at planting soil layer, lime layer is laid on regional slope surface of acid treatment, lays bentonite layer on the lime layer, lays the soil layer of planting on the bentonite layer, lays nutrition substrate on the soil layer of planting.
Furthermore, the thickness of the bentonite layer is 2-3 cm, and the thickness of the plant loam layer is 20-30 cm.
Furthermore, the slope planting plants are any one or more of plants such as acacia, bermuda grass and ramie.
The utility model has the advantages that:
the utility model provides an keep apart sour ecological restoration method of accuse can effectually realize that the vegetation covers green, reaches the ecological restoration effect that the arbor and shrub grass combined together, through the isolation measure, can effectually prevent the acid water exosmosis of administering regional deep, has both solved ecological restoration back acid water pollution problem, provides a good growing environment again for the vegetation resumes, is favorable to vegetation to grow.

Fig. 1 is a schematic view of an ecological restoration method for an isolated acid-controlled slope according to an embodiment of the present invention;
the names corresponding to the reference numbers in the drawings are as follows:
1-side slope, 2-lime layer, 3-bentonite layer, 4-planting soil layer, 5-nutrition base material and 6-plant.
Detailed Description
The following is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
The utility model provides an keep apart and control sour side slope ecological restoration structure, include lime layer 2, bentonite layer 3, plant loam layer 4, nutrition substrate 5 and plant at the plant 6 of planting loam layer, lime layer 2 is laid on the 1 surface of acid treatment area side slope, lays bentonite layer 3 on lime layer 2, lays on bentonite layer 3 and plants loam layer 4, lays on planting loam layer 4 and sets up nutrition substrate 5. The thickness of the bentonite layer is 2-3 cm, and the thickness of the planting loam layer is 20-30 cm. The slope planting plants are any one or more of plants such as locust trees, bermudagrass and ramie. The nutrition base material 5 can be formed by mixing an organic fertilizer, an inorganic fertilizer, animal manure and rice hulls according to the proportion of 1:1:1:1, and the dosage of the nutrition base material 5 is 16-20 kg/m2。
Example 1
The following are specific embodiments of the present invention: taking a slope of a certain copper ore heap leaching field as an example, the height of the slope is about 25m, firstly, the slope is leveled, and boulders and pumices on the slope are removed, so that the slope is suitable for paving materials such as a lime layer, a bentonite layer, a soil planting layer and the like. Paving a lime layer on the leveled slope surface for surface layer acidity improvement, wherein the using amount of the lime layer is 8kg/m2. And a bentonite layer is laid on the lime layer for physical barrier, and the thickness of the bentonite layer is 2 cm.
