Abstract
The invention relates to a remediation method of contaminated soil. The remediation method of the contaminated soil is characterized by specifically comprising the steps of 1) incinerating the contaminated soil in an incinerator under a temperature of 120 to 150 DEG C to enable high-molecular-weight harmful substances to converted into volatile substances or semi-volatile substances; 2) processing the incinerated smoke by dust removing, cooling and purifying, so as to enable the smoke to meet the emission standard.
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) contaminated soil is burned in incinerator, incineration temperature is 120-150 DEG C, makes the harmful substance of HMW become volatility or half volatile, 2) burn the flue gas produced, through dedusting, cooling and purified treatment, flue gas is made to reach discharge standard.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) contaminated soil is burned in incinerator, incineration temperature is 120-150 DEG C, the harmful substance of HMW is made to become volatility or half volatile, 2) burn the flue gas produced, through dedusting, cooling and purified treatment, make flue gas reach discharge standard.
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.
