摘要： A process for the treatment of waste water containing heavy metals in which sulphur components and/or metals are biologically reduced to precipitate the metals as water-insoluble metal species, which are separated from the waste water. The biological reduction and the precipitation of the metal species are carried out in a moving sand bed, in which sand particles partly immobilize the bacteria and retain the precipitated metal species, treated waste water is separated from the precipitated metal species and the precipitated metal species are subsequently separated from the sand particles. Metals like selenium and uranium can be precipitated without sulphur components, whereas metals like antimony, cadmium, copper, zinc and the like are precipitated as sulphides.

摘要： The invention relates to a hybrid biological and chemical method for decontaminating sludge containing heavy metals and pathogenic microorganisms, consisting of the following steps: the sludge is mixed with an acidic leaching solution in order to acidify the sludge with a pH which is low enough to solubilize the majority of the heavy metals and to destroy most of the pathogenic microorganisms but which is also high enough to minimize the solubilization of fertilizing elements; oxidation-reduction of more than null400 mv is maintained, liquid-solid separation occurs in order to obtain a solid fraction comprising decontaminated acidic sludge and a liquid fraction comprising heavy metals which are dissolved in a leaching solution; the sludge is neutralized: and neturalized decontaminated sludge is recovered, whereby the fertilizing elements contained therein, i.e. carbon, nitrogen and phosphorus, remain substantially unchanged in relation to the initially contaminated sludge.

摘要： To allow compact and simple design of a water treatment system capable of denitrification, an anaerobic treatment vessel 3 is provided downstream of an aerobic treatment vessel 2, and a filter layer 5 having a large number of carriers for microbes filled therein is formed in the anaerobic treatment vessel so that sulfur contents may be reduced by sulfate reducing microbes bred in the filter layer and the nitrate nitrogen is gasified by sulfur denitrification microbes with the aid of the sulfides thus obtained. In particular, the carriers preferably comprise a floating filter material in the form of plastic foam blocks that can float in the water.

摘要： A process for the decontamination of a medium comprising a particulate material contaminated with one or more metal species, the process comprising the steps of treating a body of the said medium with microbially produced sulfuric acid so as to solubilize the metal species as a metal sulfate; treating the leached metal sulfate by a bioprecipitation process which converts the said sulfate to an insoluble sulfide; separating hydrogen sulfide produced during the bioprecipitation from the insoluble metal sulfide; and oxidizing the separated hydrogen sulfide to form a reusable source of a sulfur-containing ingredient.

摘要： Hydrogen sulfide present in an aqueous system is removed and the production of hydrogen sulfide by sulfate-reducing bacteria (SRB) is eliminated by introducing into the system nitrite and nitrate and/or molybdate ions, whereby denitrifying microorganisms outcompete the sulfate-reducing bacteria for the available carbon nutrients, thus preventing the SRB from producing hydrogen sulfide and the nitrite along with the denitrifying microorganisms remove hydrogen sulfide already present in the system. The system which contains the denitrifying microorganisms and which is essentially free of hydrogen sulfide can enhance oil recovery by means of a microbial enhanced oil recovery mechanisms.

摘要： An improved method for the degradation of haloaliphatic compounds using induced cells of sulfate reducing anaerobic bacterium, particularly Desulfomonile tiedjei, is described. The cells are induced using 1,3-substituted phenyl compounds, particularly 3-halobenzoates, such as 3-fluorobenzoate which are gratuitous inducers and thus are not dehalogenated. The result is a much more rapid dehalogenation of the haloaliphatic compounds than was achieved by prior art methods using uninduced cells.

摘要： A method and system for reducing the sulfur concentration of wastewater which is to be disposed of through anaerobic treatment. Wastewater high in sulfur content is fed to a reactor having a pH level less than 6, such that the sulfate and/or sulfite compounds in the wastewater are converted by sulfate reducing bacteria into sulfide gas, thereafter exhausting the sulfide gas from the reactor. It is preferred that two anaerobic reactors be connected in series, such that the first reactor contains sulfate reduce bacteria and/or acid-forming bacteria, and the second reactor contains methane-forming bacteria and/or acid-forming bacteria.
