    摘要： The present invention relates to a method and apparatus for the continuous countercurrent desorption of targeted materials including metals, non-metals and inorganic and/or organic compounds of thereof, wherein the desorption method is divided to the two modes namely: (I) desorption and (II) re-absorption. The desorption of the target material from the loaded resin using the fresh desorbent takes place in mode (I). According to mode (I) loaded resin moves upwardly in a chamber. According to mode (II) impurities are desorbed from resin and targeted material in solution can be re-absorbed. The resin moves downwardly in another chamber during mode (II). Concentrated eluates, which are suitable for the direct economical recovery of chemical elements and/or compounds thereof, can be produced using the present invention. The apparatus of the present invention includes desorption and re-absorption zones that are configured using a 'pipe-in-pipe' construction or a U-shape construction.

    摘要： A process and apparatus for continuously stripping or recovering values from a value bearing material, typically a slurry or solution thereof. The resin and value bearing material are contacted in a counter-current manner (242, 246) in a contact zone (254, 220, 222) to load the resin with values from the value bearing material. The resin is fluidised by the value bearing material in the contact zone. The loaded resin is passed through a first washing zone (256, 224) to displace excess value bearing material. The loaded resin then passes through a stripping zone (258, 228, 226), typically an acid or alkali, to strip the values from the resin and form an eluate, which is treated further to recover the values. The stripped resin is washed in a second washing zone (260, 230), to displace excess stripping agent, and returned to the contact zone.

    摘要： Biological nutrient removal (BNR) in municipal wastewater treatment to remove carbonaceous substrates, nutrients and phosphorus, has recently become increasingly popular worldwide due to increasingly stringent regulations. Biological fluidized bed (BFB) technology, which could be potentially used for BNR processes, can provide some advantages such as high efficiency and compact structure. This present invention incorporates the fixed-film biological fluidized bed technology with the biological nutrient removal in a liquid-solid circulating fluidized bed, which has achieved the simultaneous elimination of organic carbon, nitrogen and phosphorus, in a very efficient manner and with very compact space requirements. The BNR-LSCFB has two fluidized beds, running as anoxic/anaerobic and aerobic processes to accomplish simultaneous nitrification and denitrification and to remove carbonaceous substrates, nutrients and phosphorus, with continuous liquid and solids recirculation through the anoxic/anaerobic bed and the aerobic bed. The new BNR-LSCFB system is not only an excellent alternative for conventional activated sludge type BNR technologies but is also capable of processing much higher loadings and suitable for industrial applications.

    摘要： A sieve tray column for stripping or recovering metal values from a metal value bearing material includes an elongate column body having an upper end and a lower end and a chamber defined therein. A plurality of spaced apart sieve trays are located within the chamber at intervals between the upper and lower ends. A first inlet is located intermediate the upper and lower ends of the column for introducing a value bearing material, such as a solution or slurry thereof, into the chamber, which value bearing material is arranged to flow in an upwards direction through successive trays towards the upper end. A second inlet is located at or adjacent the upper end of the column for introducing a resin into the chamber, which resin is fluidised by the upwardly moving value bearing material and caused to flow from one sieve tray to another successive sieve tray towards the lower end of the column. As the resin and the value bearing material contact each other in a counter current manner metal values from the value bearing material are absorbed onto the resin, which metal values can be recovered from the loaded resin.

    摘要： A solids separation and solids flow control device particularly suitable for use in apparatuses, devices and equipment for continuously contacting a solid with a liquid, especially fluidised-bed and moving-bed columns (1), is disclosed. The device includes separating means (2) for cyclically and controllably separating the accumulated solids, means (e.g. a bypass circuit (7, 8) or an air-lift) for generating a flow or stream of liquid by means of a hydraulic imbalance to transfer solids in a working fluid from the apparatus to metering means (3) via the separating means, and transfer means (4, 40, 5, 6) for hydraulically and sequentially transferring the solid in the working fluid from the metering means (3) to the solid-liquid separation means. A plant including said separating device for continuously contacting a solid with a liquid, and an apparatus for continuously contacting a solid with a liquid, e.g. a fluidised-bed or moving-bed column, are also disclosed.
