摘要： Method for treatment of sludge, which includes precipitated aluminium and/or iron hydroxide, whereby the sludge first is added acid and thereafter is subjected to at least one membrane filtration process, whereby a permeate or a concentrate is obtained, including trivalent aluminium and/or iron ions in solution. The aluminium and/or iron ions in the permeate, or concentrate, are crystallised (salting out) in a precipitation.

摘要： The invention relates to a de-sludging device for part of a total volume of a liquid, which contains suspended solid material and/or which can form the sludge. Said device is arranged in a container which holds the total volume of the liquid whereby at least one part of the de-sludging device, including the bottom (b) thereof, is immerged in the total volume. Said de-sludging device comprises an inlet (f) which is arranged above the bottom and which enables one part of the liquid to penetrate into the desludging device, and an outlet (g) in the form of a discharge pipe which starts above the bottom, a channel, a free overfall weir or at least one opening in the wall through which the liquid from the de-sludging device can be removed. The bottom of the de-sludging device comprises at least one outlet (h) through which the sludge which has been deposited in the desludging device is returned to the total volume of liquid or conducted to another precipating device in order to thicken the sludge. Preferably, the precipitated sludge is reintroduced into the total volume by a venturi-type nozzle. The inventive device is especially suitable for use in a method for taking automatically de-sludged bath samples for analytical purposes.

摘要： Provided is a method and apparatus for treating organic waste water, which are capable of realizing compact equipment by reducing the quantity of a sludge to be treated. Organic waste water (A) is subjected to an aerobic biological treatment in biological treatment tank (3). Then, solution (B) obtained by the treatment in the biological treatment tank (3) is solid-liquid separated into treated water (C) and sludge (D) in precipitation tank (5). A part of the sludge (D) separated in the precipitation tank (5) is returned to the biological treatment tank (3) through route (6). A part (E) of the sludge separated in the precipitation tank (5) is concentrated by concentration device (8). Thereafter, the concentrated sludge (E) is solubilized by thermophilic bacteria in solubilizing tank (10).

摘要： The invention concerns a method for purifying sludge, suspected of containing toxic and/or precious heavy metals in view of the extraction, suspended in an aqueous solution and forming a mass to be treated. Said method consists in carrying out the following operations: mixing with the mass FeCl3 until an acid pH of the solution is obtained; mixing with the mass (CO2H) and NH4Cl until metallic pro-chelates are obtained; mixing the mass with mixed alkaline sulphides until a solution with a very basic pH is obtained, to form colloidal complex iron chelates, which trap said metals; neutralising the solution by adding an acid until alkaline-ferrous sulphides and hydroxides containing said metals are precipitated; forming by centrifuging, from the mass, a liquid phase and a solid phase containing said alkaline-ferrous sulphides.

摘要： The present invention provides a biofuel cell using wastewater as a fuel. Electrochemically active microorganisms present in wastewater and active sludge sued in the present invention oxidize organic substances present in wastewater. Electrons generated from the oxidation are discharged outside of the microorganism cell and transferred directly to the electrode, thereby allowing electric current to be generated while allowing wastewater to be purified. The biofuel cell using the electrochemically active bacteria according to the present invention allows an electric energy of up to 0.22 mA to be generated, and also enables COD of the wastewater used as a fuel to be decreased from 1900 ppm to 55 ppm. Moreover, an efficiency of the biofuel cell is varied depending on the king and concentration of wastewater.
