Abstract
The invention discloses a method for treating contaminated shallow groundwater and soil by utilizing a bioremediation agent. The method is as below: isolating a contaminated site from the surrounding environment by concrete walls with depth of 2-10 m, in order to block the path of pollutants; penetrating a PVC pipe deeply into shallow underground water of the contaminated soil, pumping contaminated underground water with a water pump to a collection pool on the ground; quantitatively adding the bioremediation agent into the collection pool, and fully mixing the bioremediation agent with pumped underground water; spraying the solution in the collection pool onto the surface of the contaminated soil and slowly infiltrate the solution into the contaminated soil and underground water, so as to realize comprehensive remediation of soil and underground water. The method provided by the invention adopts a screened microbial agent with the ability to degrade organic pollutants to treat the contaminated shallow underground water and soil, and has the advantages of simple design, convenient operation, no sophisticated processing equipment, low cost, thorough processing and no secondary pollution.
Description
Technical field
The invention belongs to soil remediation technical field, be specifically related to a kind of method of utilizing biological prosthetic agent treatment to pollute phreatic water and soil.
Background technology
In recent years, along with China's economic development and city layout adjustment, the enterprise of a large amount of discharge such as many chemical fertilizer factories, insecticide factory, chemical plant organic waste moves away from down town, there is a large amount of " palm fibre ground " (abandoned, the front industry and commercial land and the facility that leave unused or do not re-use).Wherein, the concentration of part organic contaminants in soil is very high, and some pollutant even migrates to underground water and diffusion causes wider pollution.These soil organic pollutants mainly comprise petroleum hydrocarbon, Polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbon (PAHs), chlorinated solvents, explosive, agricultural chemicals etc., are all much wherein the materials of " teratogenesis, carcinogenic, mutagenesis ".These pollutants in soil may enter human body by approach such as direct contact, breathing and food chains, have potential human health risk.According to national relevant regulations, these organic polluted soils need to carry out environmental assessment and repair and could again come into operation afterwards according to pollution condition.Therefore, carry out the reparation research of organic polluted soil, the key technology of development organic polluted soil reparation is very urgent in China.
At present, the kind of the soil remediation technology of having developed is in the world a lot, as stable/curing technology, Landfill, hot analytic technique, water-washing technique, biological prosthetic etc.From renovation technique, be mainly divided into original position reparation and showering.The biological prosthetic phytoremediation, microorganism of generally can being divided into repaired and combines the types such as reparation.Compare with other method, bioremediation technology has the advantages such as low, the effective and secondary pollution of cost is few, therefore at home and abroad causes in recent years widely and pays close attention to.
But bioremediation technology also exists some problems in applying at present.For example, except soil pollution, also there is the problem of underground water pollution in contaminated site conventionally, and the often reparation for contaminated soil or underground water of present restorative procedure.Therefore, the invention provides a kind of method of utilizing biological prosthetic reagent integrated treatment to pollute phreatic water and soil, solved the difficult problem in existing contaminated soil and underground water improvement.
Summary of the invention
For addressing the above problem, the invention provides a kind of method of utilizing biological prosthetic agent treatment to pollute phreatic water and soil, solved the difficult problem in existing contaminated soil and underground water improvement.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
Utilize biological prosthetic agent treatment to pollute a method for phreatic water and soil, comprise the following steps:
Step 1) by the dark cement wall of 2-10 rice and surrounding environment isolation for contaminated site, the mobile route of blocking-up pollutant;
Step 2) pvc pipe is goed deep into the phreatic water layer of contaminated soil, with water pump by the underground water extracting of polluting in the collecting pit on ground;
Step 3) quantitatively in collecting pit, add microorganism to repair reagent, fully mix with the underground water pumping;
Step 4) surface at contaminated soil by the spray solution in collecting pit, is slowly penetrated in contaminated soil and underground water, realizes the comprehensive repair of contaminated soil and underground water.
Further, described biological prosthetic reagent be screening organic pollution is had to the microbial bacterial agent of degradation capability.
The invention has the beneficial effects as follows:
The present invention adopts the microbial bacterial agent that organic pollution is had to a degradation capability of screening process to pollute phreatic water and soil, simplicity of design, and easy to operate, without complicated treatment facility, cost is low, processes thoroughly non-secondary pollution.
The specific embodiment
Below in conjunction with embodiment, describe the present invention in detail.
