Abstract
The invention relates to a method for remedying contaminated soil. The method is characterized by comprising the following steps: (1) preparing stalks, rice straws and wheat bran according to the mass ratio of 3 to 1 to 2; (2) mixing and crushing the prepared raw materials in a crusher for 10-15 minutes to obtain particles of 10mm in size; (3) adding water of 50 percent of the total mass and mixing to obtain a mixture; and (4) applying the mixture in the soil, applying fertilizers, irrigating, adding quick lime, and regulating the PH value of the soil to 7-8 to enable contaminations in the soil to be aerobically degraded on the upper layer of the soil.
Description
Technical field
The present invention relates to a kind of soil remediation method, be specifically related to a kind of contaminated soil remediation method, belong to technical field of soil remediation.
Background technology
Soil remediation refers to and utilizes the transfer of physics, chemistry and biological method, absorbs, degrades and transform the pollutant in soil, makes its concentration be reduced to acceptable level, or is harmless material by poisonous and hazardous contamination transform.Basically, the know-why of contaminated soil remediation can comprise for: (1) changes pollutant existing forms in soil or the combination with soil, reduces its transportable property in the environment and bioavailability; (2) concentration of harmful substance in soil is reduced.
Along with improving constantly of industrial expansion and living standard, the pollution of the mankind to soil is more and more serious, soil pollution becomes global problem, each state all solves in the various way of trial, relevant method have physics, chemistry, biological etc., but these methods all do not have desirable effect, therefore, a kind of new technical scheme of exigence solves the technical problem of Industrial Wastewater Treatment.
Summary of the invention
In order to solve above-mentioned Problems existing, the invention discloses a kind of contaminated soil remediation method, this contaminated soil remediation method cost is lower, and operating efficiency is high, and the waste gas after process can reach the relevant emission standards of environmental administration, can not produce secondary pollution.
To achieve these goals, technical scheme of the present invention is as follows, a kind of contaminated soil remediation method, it is characterized in that, described contaminated soil remediation method is specific as follows, 1) stalk, straw is prepared, wheat bran is that 3:1:2 carries out proportioning, 2 according to mass ratio) raw material that proportioning is good is put into pulverizer carry out stirring pulverize, grinding time is 10-15 minute, and pulverized particles size is 10mm; 3) in the moisture adding gross mass 50% mixes, 4) being manured into soil by mixture, carry out applying fertilizer, irrigating and add quick lime, the pH value regulating soil is 7-8, and the pollutant in soil is degraded by aerobic at topsoil.
Relative to prior art, advantage of the present invention is as follows: 1) whole technical scheme is simple, and cost is lower; Reduce entreprise cost: 2) this contaminated soil remediation efficiency is high, effective, and waste gas after treatment reaches the discharge standard that Environmental Protection Agency specifies; 3) the method operates comparatively safe, has no side effect to operating personnel; 4) this processing method is fairly simple, handling safety, reduces secondary pollution, is convenient to apply on a large scale.
Detailed description of the invention
In order to deepen, to understanding of the present invention and understanding, below in conjunction with detailed description of the invention, to illustrate the present invention further.
embodiment 1:
A kind of contaminated soil remediation method, described contaminated soil remediation method is specific as follows, 1) stalk, straw is prepared, wheat bran, be that 3:1:2 carries out proportioning according to mass ratio, 2) raw material that proportioning is good is put into pulverizer and carry out stirring pulverizing, grinding time is 10-15 minute, and pulverized particles size is 10mm; 3) in the moisture adding gross mass 50% mixes, 4) being manured into soil by mixture, carry out applying fertilizer, irrigating and add quick lime, the pH value regulating soil is 7-8, and the pollutant in soil is degraded by aerobic at topsoil.The method environmental protection, pollution-free, and agricultural crop straw is made full use of, reduce rehabilitating soil cost.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned technological means, also comprises the technical scheme be made up of above technical characteristic.
Claims (1)
1. a contaminated soil remediation method, it is characterized in that, described contaminated soil remediation method is specific as follows, 1) stalk, straw is prepared, wheat bran is that 3:1:2 carries out proportioning, 2 according to mass ratio) raw material that proportioning is good is put into pulverizer carry out stirring pulverize, grinding time is 10-15 minute, and pulverized particles size is 10mm; 3) in the moisture adding gross mass 50% mixes, 4) being manured into soil by mixture, carry out applying fertilizer, irrigating and add quick lime, the pH value regulating soil is 7-8, and the pollutant in soil is degraded by aerobic at topsoil.
