Description

  The present invention relates to a method for biochemically and / or bio-mechanically treating old waste and remaining waste, for example in an old garbage dump.

  Although there is a strong desire in industrialized countries to separate household and industrial waste into recyclable materials and residual waste, the remaining waste is still of course a variety of materials, while valuable material remains unseparated. It is a mixture. In addition, the remaining waste is still largely dominated by microbiologically degradable and biological substances, which are subject to rapid microbiological fermentation, and therefore regularly and shortly, especially from a hygienic point of view. In addition, waste disposal must be attempted. Waste treatment is performed by thermal or biological treatment or by storage in a dump. Gases generated during anaerobic fermentation that occurs in such an agglomeration field, particularly odorous gases of sulfur compounds and nitrogen compounds, and methane, an explosive gas, are induced, collected, and burned by variously constructed systems. Or supplied for energy utilization.

  By the way, the problem when dismantling or moving the old garbage dump is that it avoids contamination of the groundwater, removes the odor of substances stored in the old garbage dump, prevents explosions, and at the same time, collects old garbage It is to enable easy transportation and simple new transfer of the contents of the place, and to avoid the odor problem due to the reaction gas of anaerobic decomposition.

  Accordingly, the object of the present invention is to provide a suitable method for biochemical and / or bio-mechanical treatment of old waste (eg old waste dumps) and remaining waste that can meet the above requirements. Is to present.

  In order to solve the above problems, promote and manage tiefenunabhangige in-sito-Behandlung in relation to its chemical and biochemical properties without waste and old waste depth Then, the method of the technology mentioned at the beginning is presented, characterized in that it is characterized by controlling, monitoring and monitoring.

  The advantages of the method of the present invention are, inter alia, that a controlled separation of individual segregated waste is possible from the point of view of optimum, safe and sustainable use, as well as the workers involved in this work and old waste dumps and Depending on the situation, it may be possible to protect people living near the new dump. The last advantage is that the method of the present invention allows mechanical volume optimization by separation of recyclable waste components.

  The present invention is characterized by facilitating, managing, controlling and monitoring the in-situ treatment irrespective of the depth of waste and old waste in relation to its chemical and biochemical properties. A biochemical and / or bio-mechanical treatment method for old waste and remaining waste.

The present invention provides a biochemical and / or chemical process characterized in that, in the above method, the chemical and biochemical properties are water content and / or temperature and / or CO ₂ content and / or oxygen content. Or a biological-mechanical processing method.

The present invention also provides, in the above method, biochemical and / or wherein the biochemical degradation of old waste and residual CO ₂ balance neutral organic components contained in the waste (CO ₂ -bilanzneutralen) Biological-mechanical processing method.

  The present invention is also a biochemical and / or bio-mechanical treatment method characterized by pressure ventilation of the old waste and the remaining waste in the above method.

  The present invention is also a biochemical and / or bio-mechanical treatment method characterized in that, in the above method, the pressure ventilation is carried out in a low pressure process in the pressure range of about 3-8 bar.

  The present invention also provides a biochemical and / or bio-mechanical processing method as described above characterized in that methane gas and other reaction gases are aspirated during the treatment of old waste and residual waste. is there.

  The present invention also provides a biochemical and characterized in that in the above method, a gas mixture having a high oxygen ratio compared to the normal oxygen ratio in the air is blown into the old waste and the remaining waste during the treatment. And / or biological-mechanical processing methods.

  The present invention also provides a biochemical and / or biological method characterized in that, in the above method, biological and / or chemical nutrients and / or other chemical agents are added to the gas mixture to be blown. This is a mechanical processing method.

  The present invention also provides biochemical and / or biochemical features characterized in that, in the above method, biochemical volume optimization is achieved by reducing raw waste volume with respect to its moisture content and solid total organic carbon content (TOC content). Or a biological-mechanical processing method.

  The present invention also provides a biochemical and / or biochemical process characterized in that, in the above method, gaseous or liquid biological and / or chemical reactants and bacteria are added during the treatment of old waste and remaining waste. And / or biological-mechanical processing methods.

  The present invention is also a biochemical and / or bio-mechanical treatment method characterized in that, in the above method, waste of broad particle separation (Einer Weit Gefassten Kornfraktion) is treated.

  The present invention also provides a biochemical and / or bio-mechanical treatment characterized in that in the above method mechanical volume optimization of old waste and remaining waste by separating recyclable waste components. Is the method.

  The present invention is also a biochemical and / or bio-mechanical treatment method characterized by soil engineering stabilization of old waste and remaining waste by the above method.

An advantageous implementation of this method is described below. In particular, the implementation of this method is to blow a gas mixture having a high oxygen ratio compared to the normal oxygen ratio (about 21%) in the air during treatment into the old waste and the remaining waste. The advantage of carrying out the method of the invention is that in particular methane gas (CH ₄ ) is converted into carbon dioxide (CO ₂ ) and water (2H ₂ O) by increased oxygen supply (O ₂ ), thereby providing a high degree of explosion protection. And a significant odor reduction is achieved by oxidation of malodorous substances resulting from anaerobic decomposition.
