Abstract
The invention provides an antipercolator for preventing soil pollution, which comprises an activated carbon fiber felt and a culture media which is arranged on the activated carbon fiber felt and contains microbial stains. Activated carbon fibers are large in specific surface area, fast in adsorption rate and desorption rate, high in adsorption efficiency and adsorption broad spectrum, good in adsorbing ability of various pollutants in soil and capable of avoiding soil pollution. Simultaneously, the activated carbon fiber felt can not block normal circulation of moisture in the soil, and therefore dead soil can not form. After the activated carbon fiber felt adsorbs the pollutants, the microbial strains in the culture media can decompose the absorbed pollutants in situ mode, and the pollutants can not be automatically released to cause secondary pollution. In addition, the activated carbon fiber felt can be regenerated in real time, thereby avoiding adsorbing saturation and influence on anti-seepage performance of the antipercolator, and further greatly prolonging service life of the antipercolator.
Description
Technical field
The invention belongs to the pollution prevention technique field, relate in particular to a kind of percolator that is used to prevent soil pollution.
Background technology
Along with the development of process of industrialization, soil pollution is serious day by day.With respect to air and water body, the self-purification capacity of soil is comparatively low, is difficult to repair in case pollute; And after soil polluted; Also can directly have influence on local vegetation, crops and underground water etc. and human survival has the ecological factor of direct relation, get into soil like the oil seepage after, petroleum pollution can stop up the soil aperture; Make that soil is ventilative, water penetration reduces; Change the carbon-nitrogen ratio and the carbon-phosphorus ratio of the soil organism, cause the variation of edaphone, fauna, destroy the micro-ecological environment of soil; Simultaneously, the petroleum pollution in the soil can perhaps be carried the polluted surface water body by rainwater by downward gradually leakage pollution underground water, influences water safety and crops safety; In addition, the petroleum pollution in the soil can volatilize in air, spreads and shift, and air quality is descended, and directly influences health.
Prior art discloses multiple prevention and has administered the method for soil pollution, and wherein, the prevention method science of being generally is carried out sewage irrigation, preventive measures such as applying pesticides, rational use of chemical fertilizer rationally, is difficult to fundamentally solve the soil pollution problem.The method of administering soil pollution generally comprises methods such as physics reparation, chemistry reparation or phytoremediation; Though above-mentioned improvement method has certain regulation effect; But; Because soil pollution has disguise and hysteresis quality, generally need be through pedotheque being carried out the residue detection of analytical test and crops, even could confirm the influence of human and livestock health situation through studying.That is to say, when adopting above-mentioned restorative procedure to administer soil pollution, pollute and taken place and lasting special time, soil, vegetation, crops and underground water etc. have been caused influence.Therefore, at easy Polluted area prevent mean prevention soil pollution being set in advance is to avoid one of effective way of soil pollution generation.
At present, the general generation of adopting the method prevention soil pollution of laying leakproof film in zone of leakage pollution takes place in oil field, oil plant, gas station, refuse landfill etc. easily.But this type of leakproof film is generally waterproof membrane, in block contaminant, has also stopped the normal circulation of moisture in the soil, makes this regional soil become dead soil, has destroyed its normal ecological environment.
Summary of the invention
In view of this, the technical problem that the present invention will solve is to provide a kind of percolator that is used for soil pollution, and percolator structure provided by the invention, easy to use prevents that pollutant from can not stop the circulation of moisture in soil in the time of soil percolation.
The invention provides a kind of percolator that is used to prevent soil pollution, comprising:
The NACF felt;
Be arranged on the said NACF felt, contain the culture medium of microorganism fungus kind.
Preferably, said culture medium is adsorbed on the said NACF felt.
Preferably, said microorganism fungus kind is aspergillus fungi, has a liking for oily bacterium, acid-producing bacteria, methanogen, bacillus or bacillus pumilis.
Preferably, the thickness of said NACF felt is 20cm～70cm.
Preferably, said NACF felt is a lipophile NACF felt.
Preferably, said NACF felt is polyacrylonitrile radical active carbon fiber felt or viscose-based active carbon fiber felt.
Compared with prior art, the percolator that is used to prevent soil pollution provided by the invention comprises the NACF felt and is arranged on said NACF felt, contains the culture medium of microorganism fungus kind.In said percolator, said NACF not only has bigger specific area, adsorption desorption speed is fast, adsorption efficiency is high, and has higher absorption broad spectrum activity; Each pollutant in the soil is all had better adsorption capability, can block the diffusion of pollutant in soil, prevent the generation of soil pollution; Simultaneously, the NACF felt has porous, can not stop the normal circulation of moisture in soil; Thereby can not form dead soil, can not destroy the ecological environment of laying work area; After the NACF felt adsorbs pollutant; Microorganism fungus kind in the culture medium can be with the pollutant decomposition in situ that is adsorbed; The situation that pollutant discharges, causes secondary pollution automatically can not take place not only; And can realize the real-time regeneration of NACF felt, and can not adsorb barrier performance saturated, that influence percolator, thus the service life of improving percolator greatly.In addition, the NACF felt can not combine with soil, is prone to change.
