Description
METHOD OF HARD DOMESTIC GARBAGE
LANDFILL BIOREMEDIATION
The present invention relates to technology for domestic waste processing and can' be utilized for the processing of city or industrial garbage dumps to provide their complete elimination.
Preventing environmental contamination requires the acceptance of adequate measures for prevention of this and elimination of already existent places where contamination is present.
The method of producing fuel briquettes from domestic garbage is known [SU 1713925 Al , 22.01.90], which includes mixing of garbage with water, separation of insoluble sediment, forming of briquettes from the remaining viscous combustible mass and drying of briquettes, wherein mixture of garbage with water in a mass relation 1 :(2...8) is boiled during 0,5...1 ,5 hour and the boiled mass is maintained to promote the separation of insoluble sediment and viscous combustible mass where drying of briquettes is conducted at 100°C.
The drawback of the known method of garbage processing is the considerable power consumption while boiling of the garbage in water and drying of viscous mass; the long duration of the drying process, and also the high cost of heat treatment under boiling conditions for the organic part of the garbage.
The most closely related to the invention of technical nature, purpose, results achieved, and chosen to be a prototype is the METHOD OF REWORKING GARBAGE AT TOWN DUMPS (RU2253668, Publ. 2005), comprising an operation of recovery of hard domestic garbage from dump. According to this known method, excavation and sorting of garbage is done to simultaneously separate scrap metal stones and incombustible building wastes. After profiling, the dump is divided into specific sites which are covered with peat and sawdust. Sorting of garbage is performed by means of layer-by-layer cyclic surface reworking of specific sections by detents of rotary stump pullers.
The drawback of this known method is the impossibility of using it in an open (natural) environment. This results in the impossibility of using of this technology to remediate contamination, such as pesticides, which can be applied on enormous areas in practice of agriculture, by oil and oil products contaminations of large territories; trinitrotoluene, which contaminates landfills and firing grounds and hard domestic garbage landfills treating. It is explained that for realization of the said method it is necessary to make the row of preparatory operations on excavation of garbage from a dump, of sorting of garbage with the separation of scrap metal, stones and incombustible building wastes, briquetting after sorting of remaining garbage etc. This process also is difficult since it requires treatment of hard domestic garbage on a layer-by-layer cyclic surface reworking of a site while simultaneous mixing of peat and with garbage.
The main object put into the basis of the invention claimed, are to expand the field of utilization of the method with possibility of hard domestic garbage processing in the opened (natural) environment.
For the accomplishment of the above mentioned object the concerning method of hard domestic garbage landfill bioremediation comprises the operation of recovery of hard domestic garbage from dump. In accordance with the invention claimed the further hard domestic garbage treatment is maid by the biological destruction of organic ecotoxicants of ground. First activation of aboriginal microflora is made with the simultaneous introduction into the body of dump of components based on glucose biosolutions, enzymes, surface-active substances, immobilizators preliminary purified by filtrate passed through the cleaning reactor, with the simultaneous besieging of mud and creation of optimum environment for development of microorganisms.
In a particular embodiment of the present method, activation of microflora is made by the mechanical loosening and introducing into the body of landfill, in separate deep places, composite solutions with possibility of
providing of aerobic environment in the closed layers of soil, and the acceleration of microorganisms migration is conducted by a enzymatic catalysis and penetration.,
In another embodiment of invention, additionally dispergating of oil- organic contaminations and introducing of cultures of microorganisms (bacteria), and also lower fungi forms is made.
The present invention allows to expand the field of method utilization with possibility of hard domestic garbage processing in the opened (natural) environment due to application the bioremediation process «In situ» (directly in a place), which comprises the complex of methods and technologies objected to use the biochemical potential of natural, adapted or modified biological systems, mainly microorganisms, for degradation and detoxication of pollutants. As compared to the known methods of removing environmental contamination, this method is more effective and lower cost. At the present time the alternative of bioremediation does not exist.
The bioremediation processes can be carried out by natural microorganisms because of stimulating of biodegradatory activity of these microorganisms. If in a soil, water, layers of dumps, contaminated by xenobiotics, microorganisms, capable to degrade these compounds, are absent, introduction (injection) microorganisms-biodestructors are used. In that case, when for bioremediation biologicals are used, development and adaptation of few technologies take place. The purpose of the first technology is introduction of preparations with microorganisms which will be utilized during embodiment of the second biotechnological process - bioremediation as such.
Unlike an industrial biotechnology, where the possibility of maintaining all of parameters of technological process exists, bioremediation is carried out in the open system, that is an environment. Therefore increasingly success of process of bioremediation depends on critical mass of knowledge, experience, methods, and finally, variety of microorganisms,
capable to carry out the reactions of biotdegradation. By using different solutions in the process of method embodiment, there is possibility of its adaptation in every case and to the certain object on which technological regulation will be created on the basis of engineering exploration and geological works.
Thus, substance of the offered technology of contaminated ecosystems renewing consists in maximal mobilization of internal resources of ecosystem on its primary functions renewal. The natural processes of renewal of the natural systems are very long at times. Stimulation of ground microflora by secure bioactive preparations is one of perspective methods of recovering and regeneration.
Figure shows the technological scheme of the bioremediation process at the hard domestic garbage landfill.
The method is carried out as follows. First, activating of natural microflora is made simultaneously bringing certain components based on solutions of glucose, enzymes, surface-active substances into the body of ground creating the optimum environment for development of microorganisms. At the same time the activation of microflora is made by the mechanical loosening and introducing (injecting) into the body of ground, in separate deep places, composite solutions with possibility of providing of aerobic environment in the closed layers of soil (see figure). The acceleration of microorganisms migration is conducted by a enzymatic catalysis and penetration.
The bioremediation, recultivation and regenerations procedures of hard domestic garbage landfill provide a minimization environment loads at local territory, allows to utilize substances which are present in the chosen place having the set of useful properties necessary for the hygienically effective and ecologically secure solving of many critical ecological problems.
The method claimed accelerates biotdestruction in 30-40 times. Efficiency of organic pollutants biodecomposition ranges from 80 to 95%.
Using of cultures of microorganisms (bacteria), and also lower fungi forms in the method also provides more effective processing of hard domestic garbage. So, yeasts of Candida are decomposed by aromatic compounds, Candida sp. absorbs kerosene, Candida liprolytica - crude oil. Organic compounds on the surface destructs to Actmomycor elegans and Geotrichum marium.
Thus in a method claimed, the object of expanding the field of method utilization with possibility of hard domestic garbage processing in the opened (natural) environment is achieved.
