摘要： A powdery or slurry removing agent is solidified into grains having excellent handling property with maintaining its removing capability. A removing agent, a high polymer compound, and two or more kinds of solvents are mixed and a mixture thus obtained is dried. When the high polymer compound has high solubility relative to one of the solvents and has low solubility relative to the other solvent, the high polymer compound is concentrated to a side of the good solvent for the high polymer compound and is thus subjected to phase separation according to the evaporation of the solvents during drying process and the high polymer compound then functions as a binder for combining the removing agent. Pores are formed at portions where the poor solvent for high polymer compound existed, thereby making a formed solid matter porous. As a result, it is possible to solidifying a removing agent into grains having larger grain diameter without severely deteriorating the removing capability.

摘要： A process is disclosed for recovering elemental phosphorus from an aqueous sludge and converting the residue into non-hazardous waste. The sludge is separated into (1) a slurry of water containing suspended phosphorus and dirt particles and (2) coarse solids. A flocculating agent is added to the slurry to agglomerate the suspended phosphorus and dirt particles, which are recovered from the water and are heated to melt elemental phosphorus. A coalescing agent is added to coalesce the melted elemental phosphorus, which is separated from the dirt particles. The coarse solids are mixed with hot water to melt the phosphorus sludge in it, which is then separated from inert solids. The solids are heated to burn any residual elemental phosphorus. The separated molten phosphorus sludge is stirred with a solution of chromic acid to recover the phosphorus as a separate phase. A reducing agent is added to the remaining water and solids to reduce the Cr+6 to Cr+3. Finally, an alkali is added to the water and solids to react the residual phosphorus and form phosphorous compounds. The reaction mass is filtered and the filter cake can be placed in a landfill as a non-hazardous waste.

摘要： The invention relates to a method and apparatus for removing impurities from waste water by electroflotation. The waste water to be cleaned is conducted through an electrolytic cell. Electrolysis is performed between two electrodes (1, 2) of different electronegativities, such that the more electronegative electrode (1), which is non-wearing in a cleaning process, is used for producing hydrogen gas and hydroxyl ions from water. The less electronegative electrode (2), which is an active, wearing electrode in a cleaning process, is used for producing metal ions in a solution to be cleaned. In addition to this basic reaction, a desired oxidation-reduction reaction is initiated in the cell in a strictly controlled electric field for removing one or more designated impurities from cleaned water.

摘要： An electrolytic treatment apparatus and method by simply subjecting a chemical plating waste liquor containing phosphorus components and organic compounds to electrolytic treatment, thereby reducing the amount of impurities in the waste liquor to a level at which the waste liquor can be discharged. The chemical plating waste liquor containing hypophosphorous acid, phosphorous acid and organic compounds is subjected to electrolytic treatment in an electrolytic cell having a conductive diamond electrode as an anode. The conductive diamond electrode oxidizes or oxidatively decomposes the phosphorus components and organic compounds in the waste liquor substantially simultaneously, thereby reducing the amount of impurities to a level at which the waste liquor can be discharged.
