Abstract
A kind of soil remediation medicament, including ethanedioic acid, humic acid, sulfuric acid, manganese sulfate, microbial bacterial agent and chicken manure, eluent preparation technology is simple, at room temperature, the elution effect of heavy metal is stronger simultaneously, the destruction to soil property can be reduced, while it is preferable to add fertility after the efficiency of chemical leaching, soil remediation.
Description
Technology neighborhood
The invention belongs to soil remediation field, and in particular to a kind of soil remediation medicament.
Soil is the material base of human society survival and development, in recent years, and economic fast development causes soil pollution
It is increasingly severe.The recovery technique of current contaminated soil includes physics, chemical and biological prosthetic three major types, and wherein chemical leaching is repaiied
Recovering technology receives favor due to can quickly, thoroughly remove heavy metal-polluted soil and organic pollution materials.Chemical leaching is main
Refer to elute from soil pollutant using water, eluent or other materials, even gas bleed soil, make soil
In heavy metal be transferred among liquid, obtain clean soil, then the method for being handled solution, being recycled.
The principal element of restriction chemical leaching has two aspects at present：One is the selection of chemical leaching, chemical leaching
The selection of eluent directly determines the efficiency of elution in reparation, and the process to whole chemical leaching is most important.Therefore, find and close
It is the most key and important for elution technique to fit effective Soil leaching agent, and the arsenic in soil eluent generally used is divided into
Inorganic eluent,
Chelating agent and biosurfactant etc..Two be the recovery and recycling of eluent.The recovery and utilization of eluent have
It is beneficial to
Rehabilitation cost is reduced, is economized on resources.
Invention broadly provides a kind of soil remediation medicament, the pharmaceutical production is with low cost, can fast and efficiently go
Except the heavy metal in soil, the fertility of soil is kept.
The technical solution adopted in the present invention is as follows：
A kind of soil remediation medicament, in parts by weight it include following component：2 parts of ethanedioic acid, 2 parts of humic acid, sulfuric acid 1
Part, 0.5 part of manganese sulfate, 1 part of microbial bacterial agent and 5 parts of chicken manure.
A kind of as the present invention limits, and the sulfuric acid concentration is 0 .03mol/L, and the concentration of ethanedioic acid and humic acid is
0.1-0.2mol/L, the concentration of manganese sulfate is 0.03mol/L.
As another restriction of the present invention, heavy-metal contaminated soil is one or more of in Cr, Zn, Cd and Pb
The soil of heavy-metal composite pollution.
The present invention also has a kind of restriction, and the eluent is added among the soil of heavy metal pollution, and soil ratio is 1:3 enter
Row mixing, stirs mud-water separation after 4h, standing.
Chemical leaching used in the present invention, can be to drenching for the difference of content of beary metal contained by different contaminated soils
The concentration of lotion, the parameter such as processing time carries out certain adjustment.Soil after elution processing is filled out back after being cleaned through clear water
Original place,
Secondary pollution is not resulted in.
Advantage of the invention compared with other soil remediation medicaments is：
(1) the soil remediation medicament configuration technique is simple, and raw material is easy to get, and effect is notable, with preferable economic benefit；
(2) the soil remediation medicament can quickly remove the heavy metal in contaminated soil, be imitated compared with other chemical leachings
More preferably, the elution time is shorter for fruit.
(3) the soil remediation medicament uses rear recyclable recycling, it is easy to separates, remains less and residual from soil
Stay eluent easily to be decomposed by edaphon, reduce the destruction to soil property and the fertility of soil can be kept.
The present invention is repaired suitable for heavy metal contaminated soil.
Embodiment
A kind of soil remediation medicament of embodiment 1
Take 0.1mol/L ethanedioic acids 2g, 0.2 humic acid 2g, 0 .03mol/L sulfuric acid, 1 g, tri- kinds of materials to be mixed, formed water-soluble
Liquid, conduct after the g of chicken manure 5 after the g of 0.03mol/L manganese sulfates 0.5, microbial bacterial agent 1g are added thereto and is crushed is well mixed
Eluent.
A kind of repairing effect of soil remediation medicament of embodiment 2
Take heavy metal pollution（Containing Cr and Cd）Soil in centrifuge tube, add above-described embodiment 1 configure soil remediation medicament,
It is 1 to form Tu Shui ratios:3, vibration elution 4h on constant temperature oscillator is placed at a temperature of 25 DEG C, with 4000rpm after the completion of vibration
Rotating speed centrifuges 20min, abandons its eluate, takes out remaining soil, air-dries the concentration that four kinds of metals in soil are determined after grinding, as a result
It is as follows：
Cr and Cd contents in before processing soil are respectively 395 .4mg/L, 9 .7mg/L, and the Cr and Cd after processing in soil contain
Amount is respectively 106 .3mg/L, 1 .6mg/L, and the reduced rate of two kinds of metals is respectively 73 .1%, 83 .5%.
Claims (4)
