摘要： In a method and an apparatus for cleaning tar-bearing waste water (17), a mixture of water and hydrocarbons, e.g. comprising polyaromatic hydrocarbons and phenols, the mixture is separated into a low-boiling-point part and a high-boiling-point part, bringing the low-boiling-point part on vapour form in a boiler (1), and the low-boiling-point part is cracked in vapour form at a high temperature in a reactor (2), providing light combustible gases, which can be utilised in e.g. gas engines, gas turbines or the like. Furthermore, the high-boiling-point part may be used for energy supply to the process or other processes or as an alternative be cracked for providing light combustible gases.

摘要： In a method for reducing the leaching of oxyanion forming elements, in particular chromium, from materials containing environmentally noxious constituents, especially from incineration residues, especially flue gas cleaning products from waste incineration, in particular fly ash, the said materials are admixed with an aqueous medium such as water in a closed container in a liquid-solid ratio sufficient to cause reducing conditions capable of stabilizing oxyanion forming elements, in particular chromium, due to oxidation of metallic Al, Zn, Fe, and other free metals present in the said materials.

摘要： In a method for the treatment, in particular stabilization, of materials containing environmentally noxious constituents, especially from the incineration of waste, in which the materials are treated with ferrous compounds and water, the materials are washed and stabilized chemically using a solution containing ferrous ions (Fe ) which allows the formation of stabilizing ferric oxides (Fe ) on the materials, the ferric oxide formation being carried out by means of an oxidation under controlled conditions with respect to the nature and the amount of oxidizing agent, temperature and pH, whereafter, if desired, the treated materials are subjected to a thermal after-treatment. A plant for carrying out the said method comprises a silo (2) containing materials containing environmentally noxious constituents; a reactor (1) to which the said materials ar fed; a tank (9) and a return water tank (7) and silos (3, 4) containing ferrous salt solution and, if desired, other chemicals, washing-water and the said chemicals being fed to the said reactor (1), the reactor contents being stirred; a sedimentation tank (5) to which the washing-water is fed; a centrifuge or filter press (6) in which the precipitate formed is dewatered; and means for aerating the water in the said tank (5) for decreasing the pH and oxidation of the water.
