Description
Technical field
The present invention relates to soil and groudwater remediation technology, relate in particular to a kind of medicament that utilizes oxygenant and special efficacy bacterial classification to repair non-chloro organic polluted soil and underground water.
Background technology
Along with the development in industrialization city, increasing pollutent enters into soil and groundwater, but some pollutent is difficult to be biodegradable, remain in for a long time in environment, a lot of pollutents enter human body by underground water or other approach, human body is formed to great threat, cause human body to produce a lot of diseases.The type of soil and groundwater pollution there is no strict division at present, as the attribute from pollutent is considered ,-as can be divided into heavy metal contamination, petroleum-type organism stains, volatility, half volatile are compound polluted, chlorinatedorganic stains, and nuclear pollution etc.Wherein, non-chlorinatedorganic pollute comprise the place of petroleum-type, volatility, half volatile and people's daily life the tightst.
The technology of in prior art, organic contamination source being processed mainly contains biological ventilation, natural degradation, biological heap, chemical oxidation, air lift technology, thermal treatment, excavation soil removal and replacement etc.Wherein, taking biological restoration as basic biology ventilation, natural degradation, biological heap method etc., rehabilitation cost is lower, but due to organic pollutant complicated components, the difficult degradation of part component, physical environment is severe etc., causes reparation speed slow, and degradation rate is low; Be basic air lift technology, thermal treatment, soil replacement method etc. based on physics reparation, reparation speed is fast, but rehabilitation cost is high, pollutent is not removed, and increases the shortcomings such as landfill yard burden.High-level oxidation technology based on basis, chemistry reparation position is that development in recent years is got up and is subject to the new technique of paying close attention to both at home and abroad, the a large amount of organic pollutants of degraded that can non-selectivity, but exist oxidation specific aim poor, intermediate oxidation product is often difficult to further occur the shortcoming that complete oxidation decomposes.
Summary of the invention
The present invention is just for the technical problem existing in prior art, advanced oxidation and biotechnology are had complementary advantages, a kind of bio combined oxygenant is provided, and hereinafter to be referred as the long-acting short biological oxidant of BIOX, this oxygenant oxidation efficiency is high, application is convenient, security is good.
To achieve these goals, technical scheme of the present invention is as follows: the long-acting short biological oxidant of BIOX, it is characterized in that, described short biological oxidant is made up of oxidant-precursor, stablizer and bio-carrier, wherein said composition quality per-cent is, oxidant-precursor is 40%-80%, and stablizer is 10%-40%, and bio-carrier is 1%-20%.
In use, first BIOX can continue to produce oxygenant, by advanced oxidation approach, and fast degradation organic pollutent.For the intermediate product of the further oxygenolysis of difficulty producing after advanced oxidation, BIOX, by the growth of the original indigenous degradation flora of high efficiency flora or stimulation place of load, realizes difficulty is decomposed to the degradable of intermediate product.
The efficient degradation flora of BIOX load, be according to target contaminant with place characteristic etc. by screening, separate, enrichment, optimization proportioning make, bio-carrier is by the special efficacy degraded bacterial classification after various selectivity load cultivations, domestication, screening, as the cold-resistant bacterial classification for low temp area, for the salt tolerant bacterial classification in saltings, for the resistance to toadstool kind of poisonous phenols etc., and selectivity is used as required, pointed strong, the feature that community function is stable.As compared with ozone, Fenton reagent, hydrogen peroxide etc., BIOX has the advantages that oxidation efficiency is high, application is convenient, security is good with traditional advanced oxidation agent.
As a modification of the present invention, described short biological oxidant ingredient mass percent is, oxidant-precursor is 50%-75%, and stablizer is 20%-35%, and bio-carrier is 5%-15%.
