Description
Technical field
The present invention relates to mining soil recovery technique field, and in particular to a kind of mining area nickel contamination soil remediation method.
Background technology
Diggings soil nickel contamination is serious, and agricultural use is typically used as after China's mining area nickel contamination soil remediation, if repaired
Not exclusively, nickel is entered in plant by root system, causes plant undergrowth, and plant is caused harm, and even results in Plant death.
Nickel can be put aside in plant, when nickel savings beyond normal contents plant enter food chain when, will influence animal or even
The health of the mankind.
At present, China's nickel contamination soil majority is not governed, and huge hidden danger is caused to environment.Soil nickel contamination has
Disguised, hysteresis quality and chronicity, cause harm to ecological environment, and nickel is animal migration pollutant, after nickel enters in soil, quilt
Contaminated soil scope gradually expands.
The recovery technique for nickel contamination soil mainly includes microorganism removal method, chemical method in the prior art(Medicament is washed
Wash, thermally decompose), Physical(Electric current makes charged particle migration etc.)And planting plants, substantial amounts of method is also in laboratory
Conceptual phase, field conduct is more difficult, meanwhile, existing nickel contamination land treatment technique technique falls behind relatively, result in nickel contamination
Land remediation efficiency is low, high cost, secondary pollution and the big problem of environmental risk.
The soil in mining area is uneven, and soil nickel content differs greatly, therefore when being repaired to soil, it is necessary to carry out
Collecting soil sample and analysis are tested.During collection pedotheque, because soil nickel content difference is too big, traditional is " S " or " right
Linea angulata " method is difficult to react the actual conditions of soil nickel content, when being repaired to nickel contamination soil at present, does not take into full account soil
The Spatial Difference of earth nickel content, Spatial Difference is not accounted in collecting soil sample and on repairing, and there is certain deficiency.
The content of the invention
In order to solve the above-mentioned technical problem, it is an object of the invention to provide a kind of mining area nickel contamination soil remediation method, repair
Multiple efficiency high, low cost, non-secondary pollution are suited measures to local conditions, and more precisely can quickly repair mining area nickel contamination soil, effectively resistance
Only nickel is migrated in soil, prevents soil pollution scope from expanding, and long-term for soil provides nutrition in soil remediation process
Element, improves the use value of soil.
The technical solution adopted in the present invention is:A kind of mining area nickel contamination soil remediation method, first using grid multiple spot
Method carries out collecting soil sample, and then the nickel content of the pedotheque to being gathered is measured, and is surveyed according to soil nickel content
Result is determined by soil divided rank, the soil of the nickel contamination upper soll layer thickness 10-18cm that then turns over, further according to the soil for being divided
Grade applies the soil-repairing agent and slow-releasing granules to application amount, and finally nickel contamination soil is irrigated, and water irrigating depth is
More than 20cm, relative moisture of the soil keeps the relative humidity 10~20 days up to more than 85%, and the soil-repairing agent is
It is made up of absorption carrier and the effective viable bacteria being adsorbed on the carrier, and the effective viable bacteria contained in every gram of soil-repairing agent is total
Number is(5~150)×108CFU;Effective viable bacteria is made up of the mixing of Halomonas, colloid bacillus and rainbow conk keyhole bacterium,
And the living bacteria count ratio of Halomonas, colloid bacillus and rainbow conk keyhole bacterium is 1.5~2:1~2:2~3.5, it is described
Absorption carrier is to compare 1 according to weight by coconut palm chaff, diatomite and bentonite:2:1 is mixed;
The slow-releasing granules are by 120~140 parts of Flaxseed cakes, 50~60 parts of peony seeds shells, 100~120 according to weight ratio
Part stalk, 30~40 parts of bamboo charcoal powders and 150~200 parts of modified rice bran protein solution are made, and the modified rice bran protein solution is pressed
It is to sequentially add 0.5~1 part of glutamine after being mixed with 100-120 parts of distilled water by 10-15 parts of rice bran protein to turn according to weight ratio
Ammonia enzyme and 0.1~0.2 part of potassium diformate heat 2h at a temperature of 45~50 DEG C and are obtained.
Size of mesh opening in the grid multipoint method for being used for(10~45)m×(10~45)m.
The specific preparation method of the slow-releasing granules is:Flaxseed cake, peony seeds shell, straw are weighed according to above-mentioned weight ratio
Stalk, bamboo charcoal powder, rice bran protein, distilled water, glutamine transaminage and potassium diformate, peony seeds shell and the stalk mixing that will be weighed
Crushing is the powder of 200~400 mesh in being put into pulverizer afterwards, and the powder that will be obtained dries after mixing with bamboo charcoal powder, Flaxseed cake
It is dry, granulation in comminutor is subsequently placed in, hybrid particles are obtained, then take addition glutamine turn after rice bran protein and distilled water mixing
Ammonia enzyme and potassium diformate are simultaneously heated to 45~50 DEG C, keep the temperature 2 hours, obtain modified rice bran protein solution, then will be modified
Rice bran protein solution spraying is obtained slow-releasing granules on hybrid particles after drying.
It is described to refer to by soil divided rank according to soil nickel content measurement result:According to soil nickel content measurement result,
Soil is divided into five grades, the soil nickel content of one-level soil is less than 9.5mg/kg, and the soil nickel content of second grade soil is not
Less than 9.5mg/kg and less than 20 mg/kg, the soil nickel content of three-level soil is not less than 20 mg/kg and less than 38 mg/kg,
The soil nickel content of level Four soil is not less than 38mg/kg and less than 49mg/kg, and the soil nickel content of Pyatyi soil is not less than
56mg/kg;
Soil-repairing agent and sustained release grain amount applied in the soil of five grades are:Soil in grid is one-level soil
