These researchers' mud treatments are not suitable for large-scale soil treatment. Usually in all attempts, the anaerobic stacking of H C B cannot be completely dechlorinated and the aromatic ring is cleaved, which usually leaves a single or polychlorinated toxic metabolite. Only partial chlorine atom removal was shown during anaerobic degradation, and a single chlorobenzene was never shown. SUMMARY OF THE INVENTION The present invention provides a method for decontaminating soil and / or sediments containing H C B pollutants and converting the pollutants into harmless substances. This method can decontaminate the soil to a desired degree, that is, partially decontaminate or completely correct it. More specifically, the method for removing HC B pollution in the soil provided by the present invention includes: C a) Preparation of an inoculum 'manufacturing a A mixture of contaminated soil containing a small amount of pollutants and a nutrient-free heterotrophic culture medium, and the mixture is stored at 20 ° C to 30 ° C for a sufficient time to allow microorganisms to adapt to the environment to produce and produce viable Anaerobic and aerobic microorganisms, can convert pollutants present in the soil into harmless substances, and in the anaerobic and aerobic decontamination treatment state This paper is suitable for the standard (CNS) A4 ( 210 * 297 public love) -------, 1; --- Gan ^ ------- order --------- line-- (Please read the note on the back first Please fill in this page again for matters) -5- Seal of the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economy-* '| 私 ^ 446585 Α7 _ Β7 V.

The oxidation-reduction potential of the stacking mixture is less than about minus 200 m V until the pollutant is degraded in a significant amount: and (e) the stacking mixture is oxidized to increase its oxidation-reduction potential to above 10 OmV. And maintain a redox potential of more than about 10 to a significant amount of pollutants are degraded. The method includes preparing an inoculum containing a viable anaerobic and aerobic microbial population to convert pollutants to harmless substances, and surviving through this anaerobic and aerobic treatment. These soils are then treated in a solid state with these microorganisms, as described below. The inoculum is prepared by mixing a small amount of contaminants, preferably 10 to 100 by weight of the final inoculation mixture, and mixing it with a heterotrophic medium formulated with a conventional high-nutrient aqueous solution. Ideally adding some soil to this mixture is still liquid. This liquid mixture is then stored at 20 ° C to 3 ° C for 6 to 10 weeks. During this period, endogenous anaerobic and aerobic microorganisms that can adapt to the environment are formed, and special pollutants can be transformed into harmless substances, and they can still survive through this anaerobic and aerobic treatment. Decontamination treatment includes mixing HCB-contaminated soil with improved materials to form a solid stacking mixture containing organic nutrient substances, and applying the National Solid State Standard (CNS) A4 specification (210 * 297mm 3E) from 20 to this paper size (Please read the precautions on the back before filling in this page) --- a ± ^ ------- order --------- line-> ---------- ---------- ^ --- -6- Employees' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, Cooperative Printing and Printing Co., Ltd. 446585 Α7 ____ Β7 V.

The description of the invention (5) is transferred from the HCB molecule Except for one or more chlorine atoms, η CB 尙 is not completely degraded to harmless substances. '' Decontamination effect '' means that the transformed pollutant is a harmless substance, including biological degradation of the pollutant and / or binding of the pollutant to soil or other substances. Α Correction means decontamination of contaminants in soil / sediment to the point where it is not objectionable. Soil means land, for example: humus soil, sand and granular rocks, and sediments that come from above or below the water surface. DETAILED DESCRIPTION OF THE INVENTION In the degradation step of the treatment of the present invention, the soil to be decontaminated must contain a treatment capable of degrading the contaminant through the treatment of a suitable type of viable microorganisms. Therefore, anaerobic and aerobic microorganisms must be present, and these microorganisms must be able to survive in anaerobic and aerobic conditions so that they can exist in this process. Furthermore, when the stacked mixture is treated in an anaerobic and aerobic state, this microbiota cannot be killed or adversely affected so that they do not sufficiently degrade HCB. These microorganisms are usually bacteria, fungi, actinomycetes, and a small number of protozoa. As will be described later, the first step of the present invention is to prepare a suitable inoculum from microorganisms. The microorganisms are initially present in the soil to be treated so that they can adapt to contaminants and decontaminate them. Additional viable microorganisms can be recycled from decontaminated soil. In the practice of the present invention, the preparation of the solid heaping mixture is achieved by decontamination by mixing suitable soil improvement materials into the soil, wherein the improvement materials account for at least 10% of the total amount, up to the weight of the mixture.

Soil improvement materials include a customary organic nutrient source for microorganisms during the composting process. = Better modification nutrients are agricultural waste and municipal sewage sludge, such as horse, cattle, sheep, turkey, chicken or fish manure. Or activated sewage sludge is preferred. Alfalfa, hay, sawdust, sludge, pasture, and other bulking materials may be present in the composting mixture, and the origin of the manure may be specifically added. Inoculum is added to the stacking mixture in sufficient amounts to significantly affect the population of microorganisms. At least 1% is required, and preferably 1-2% of inoculum volume / volume is added to the improved material. In some cases it may be necessary to include a surfactant in soil improvement to make pollutants more susceptible to biological degradation. Suitable surface-active agents include polysorbates, caprylic polyols, anionic alkyl sulfates, anionic alkyl aryl sulfates, and ethoxylates. Examples of suitable surfactants include TWEEN® nonionic surfactants from ICI Americas, Inc., TRITON® nonionic surfactant products from Union Carbide, and DAWNTM detergent products from Procter & Gamble. Improved substances can also contain or supplement liquid or solid organic or inorganic nutrients. Organic substances containing high levels of nitrate and phosphate are often used. The stacked mixture is maintained in a solid state containing moisture. Through the whole process, the water retention (w H C) of the mixture whose humidity is maintained at less than 1000% is preferably about 40 to 70%. After mixing, the biodegradation of organic substances in the mixture begins, increasing the temperature and consuming oxygen to make it anaerobic. This paper is then mixed.

Invention Note (7) The temperature of the substance is maintained in the range of 20-65 ° C, which can be easily accomplished by controlling the air movement through the stacking mixture (such as through a duct) and / or by adding nutrients. Below 20 ° C, biodegradation is slow to comply with economic effects, while above 65 ° C, too many microorganisms may be killed. The preferred temperature range is about 20-50 ° C. The anaerobic microorganisms in the composting mixture will survive the subsequent aerobic degradation step, and the anaerobic microorganisms will survive any need for the continued anaerobic degradation step. Therefore, the treatment process of the present invention must maintain the survival of aerobic and anaerobic degradation microorganisms. During the anaerobic step, the stacking mixture maintains a low redox potential, at least about negative 200 mV, and preferably between negative 300 mV and 500 mV. This range has been found to be the most suitable range for anaerobic processes. The redox potential is maintained in this range by the movement of humid air through the stacking process and / or by addition of conventional reducing agents such as sulfites and acetate reducing compounds. 11 The first anaerobic step and any subsequent The oxygen step continues until a significant amount of pollutants are degraded, which can be determined by analysis. A typical situation is the degradation of 30% to 70% of the initial H C B pollutant content in the first anaerobic step. After a significant reduction in the content of contaminants in the soil / manure mixture during the first anaerobic phase, the mixture is oxidized by any suitable method, preferably by aerating the air and / or mixing with the mixture to achieve an aerobic state. The redox potential during aerobic treatment is suitable for sufficient oxidation. It must be maintained above 1000 m ν. This aerobic state further activates the degradation to produce harmless substances.

Description of the invention (8) Continue until the amount of pollutants treated with aerobic treatment is significantly degraded. In most cases, biodegradation of pollutants to an acceptable level of correction was not achieved during the first anaerobic / aerobic treatment sequence. During the 'excellent anaerobic / aerobic treatment sequence, continuous repetition of one or more times is necessary to decontaminate the soil to an acceptable level. After this many times, the sequential better treatment can achieve the effect of continuous complete correction and improvement. A desirable characteristic of this treatment is that the degradation microorganisms need to remain active during the anaerobic / aerobic treatment cycle, so that it is not necessary to replenish the microorganisms before repeating the treatment cycle. However, it is necessary to add more improved substances, manure or other commonly used fermentation components, mainly to supplement the supply of this organic raw material, and also to introduce more expansion agents. As mentioned earlier, in order to effectively carry out the process of the present invention, it is necessary to maintain the proper redox potential of the stacked mixture in the anaerobic and aerobic steps. A suitable redox potential can be maintained by adding conventional nutrients and / or reducing agents such as sulfite and / or acetate compounds. Absolute anaerobic and aerobic conditions are required (although transient local deviations are to be expected). For the purposes of the present invention, an oxidation-reduction potential of less than negative 20 OmV is considered anaerobic, and is necessary for the anaerobic step: and an oxidation-reduction potential greater than positive 10 OmV is considered aerobic, and it is the essential. During the anaerobic step, the redox potential is preferably from 300 to 500 m V: and during the aerobic step, the redox potential is preferably from 2000 to 300 m V. A redox potential between negative 20 OmV and positive 10 OmV is considered hypoxic. In the present invention, from the anaerobic state to the aerobic state1 and, in contrast, the anoxic state is present in the stacking mixture.

Description of the Invention (9) The degradation of some pollutants, but the rate is very slow. Therefore, the rapid transition from one state to another can accelerate the completeness It may be possible to design the compound to have an anaerobic state in one part of the compounded mixture and an aerobic state in the other part when implementing the compound. This is suitable because different parts of the compounded mixture have different Initial pollutant concentration and / or degradation rate. Therefore, in order to achieve consistent degradation, it is necessary for some parts of the stack to maintain a long anaerobic or aerobic state. High microbial counts occur during the stacking process , Preferably a maximum of 108 aerobic colony forming units (ci U) per gram, which can be measured by standard plate counting techniques without A maximum of 106 cf U / g is preferred. These microbial counts, of course, include microorganisms other than degrading contaminants. This treatment is performed in a stack of processing vessels, usually in a container cell or in a row. The soil to be treated can be analyzed and piled in the laboratory to determine the most suitable improved composition conditions, as well as the time and sequence number of the anaerobic / aerobic treatment. As described above, the process of the present invention includes the anaerobic reactor. The anaerobic composting stage is followed by the processing stage. However, the initial anaerobic treatment of the soil can be performed before the first anaerobic stage to reduce the content of pre-existing unsuitable substances. The following examples illustrate the invention Example 1 Preparation of an inoculum for decontamination of soil containing HCB, 25 ml of diluted heterogeneous culture medium * mixed 6 2 5 microliters of 2 mg / ml HC Β methanol solution and 5 0% of uncontaminated soil.

Description of the invention (10) The species are stored in an anaerobic chamber at 2 ° C for 6 weeks. One milliliter of soil containing approximately 25 ppm of HCB was then mixed with a milled milliliter of straw containing 4000 milliliters of cow manure and the 50 milliliter inoculum described above. Cover it once, and store the mixture in the indoor anaerobic stacking site. The water retention capacity and redox capacity of the anaerobic stacking mixture are about 70%, less than 2 5 ◦ m V, and HCB at 2 2 ° C. Degradation. Thereafter, the oxidation-reduction potential is raised to an aerobic state by oxidation. During this period, W H C and oxidation also averaged about 70%, respectively, and further pollutant degradation above 200 mV and 34 during the aerobic phase. The 8-week phase of these continuous anaerobic / aerobic treatments is heavy. As a result, more pollutants are degraded. The degradation obtained in this experiment can be corrected in large-scale decontamination according to this technology. * Diluted heterogeneous culture medium composition: kg (60 ml of the compound, and 50 of the same sample were reprocessed for 6 weeks. At this stage and the temperature averaged, a significant increase in the stacking potential and temperature ° C occurred, It will happen again and again, and it can indicate the most suitable fit with a great degree of effect, --- ^ ---------- Order --------- line-- "(Please read first Please fill out this page on the back of the page.)
