    摘要： The method according to the invention provides for in situ treatment of two types of waste, i.e. heterogeneous contaminated material and ash and/or poculants to a final composite-filler with a wide range of applications. This was not made possible by the hitherto known methods. The method comprises preparation of an adequate fraction of the heterogeneous contaminated material by sieving and crushing and mixing of individual components in a mixing device. The mixing is performed in two phases, first, the crushed heterogeneous contaminated material is given into the mixing device, this material functions as an aggregate in the composite, then ash and/or poculants are added until all grains of the aggregate are covered in ash and the dry mixture gets homogenized. To the homogenized dry mixture water is then added, in compliance with the requirement of the recipe. The wet reaction mixture is stirred until complete ash is in contact with water, wherewith the reaction is activated throughout the entire volume of the reaction mixture. In the process of composite formation, the ash and/or the poculants assume the role of a solidifier and stabilizer. Due to a high pH value of the mixture which reaches the values above 12.0, the salts of heavy metals get converted into a water insoluble form and are not leached out, thus the final composite is inert.

    摘要： This invention relates to a process for reducing the levels of contamination of soils polluted by DDT, DDE, DDD and/or their isomers which comprises the steps of:
    (i) excavating the polluted soil;
    (ii) sieving the excavated soil to separate out a first part with particle size measurement less than a predetermined threshold value;
    (iii) adding to a predetermined quantity of the first part of sieved polluted soil a first aqueous solution containing one or more enzymes in such a way as to obtain a solid - liquid mass;
    (iv) stirring the solid - liquid mass for a predetermined time so that said one or more enzymes catalyse the partial or total degradation of said pollutant; and
    (v) separating the solid - liquid mass into a residual aqueous suspension and into a solid part.
