摘要： PURPOSE:To remove solid matter from waste water without the use of washing water, by restraining a filter layer composed of the group of particles having specific gravity smaller than that of waste water with water-permeable supporting plates provided at an upper part and a side wall, letting the waste water flow through the filter layer along a horizontal direcion to treat the waste water with microbes, and forming a circulating current to remove the solid matter caught by the filter. CONSTITUTION:Waste water is introduced from an apparatus for treating waste water with microbes as pretreatment into the main apparaus, let flow through a packed layer 7 composed of the group of said floating particles along a horizontl direction and then drained 2, to catch and remove solid matter in the waste water with the layer 7. A water level gradually rises with the increase of pressure loss in the filter layer 7 in due course. When the water level reaches a position near the top end of a draft tube 5, the outflow 2 and the inflow 1 of water are stopped. In succession, air is charged 3 in the tube 5 through its lower part to start washing the filter layer 7, and the air charged 3 is raised inside the tube 5 to form the circulating current of water flowing downwards along the outer part of the filter layer 7. The part of the filter layer 7 is expanded by said descending current to exclude solid matter caught in the filter layer 7 and to peel off solid matter adherent to the surface of particles by the mutual impinging action of the particles. In this way, the filter layer 7 is regenerated.

摘要： PURPOSE:To make oxidative decomposition of thiocyan ions easy by bringing waste water contg. thiocyan into contact with 1 or >=2 kinds of oxygen, oxygen-contg. gas, oxygen producing materials in the presence of a Raney copper catalyst. CONSTITUTION:Waste water contg. thiocyan is brought into contact with 1 or >=2 kinds selected from the group consisting of pure oxygen, oxygen-contg. gases and materials generating oxygen in the presence of a Raney copper catalyst by a system such as perfect mixing type, stationary bed, fluidized bed, moving bed or the like, whereby thiocyan ions are oxidized and decomposed. The Raney copper catalyst is obtd. by acting an aq. alkali soln. or an aq. acid soln. upon an alloy of copper and >=1 kind of metals to be attacked by water, alkalis, acids, etc. The quantity of the oxygen to be supplied during the catalytic oxidative reaction of the thiocyan is sufficient if it is 1.2 times the theoretical quantity required for oxidation, and the temp. and pressure of the reaction may be ordinary temp. and atmospheric pressure.

摘要： PURPOSE:To oxidize and decompose cyanogen within a short period with simplified operation, by bringing cyanogen-contng. waste liquid into contact with one or more selected from the group consisting of pure oxygen, oxygen-contng. gas and oxygen-generating substance in the presence of Raney copper catalyst. CONSTITUTION:Waste water containing cyanide such as cyanic ion or cyanic complex ion is brought into contact with one or more selected from the group consisting of pure oxygen, oxygen-contng. gas and oxygen-generating substance in the presence of Raney copper catalyst by a method such as a complete mixed type, stationary bed, fluidized bed or moving bed, to oxidize and decompose the cyanide. Raney catalyst is an active metal prepared by reacting copper and one or more metals (Mg, Al, Zn, Fe, etc.) to be corroded by water, alkali, acid or the like with an alkaline water solution such as NaOH or an acidic water solution such as hydrochloric acid.

摘要： PURPOSE:To reduce COD of waste water contg. PVA to lower than a normal value, by bringing the waste water contg. PVA into contact with oxygen or an oxygen-generating substance in the presence of Raney copper catalyst to oxidize and decompose PVA. CONSTITUTION:An alloy of Cu with Mg, Al, Zn or the like is reacted with an aqueous alkali or acid solution to prepare Raney copper catalyst. The catalyst is brought into contact with waste water contg. PVA in a reaction vessel, and one or more selected from pure oxygen, air, oxygen-contg. gas, hydrogen peroxide and the like is added to the water to carry out the reaction. Thus, PVA in the waste water is decomposed, its COD is reduced to a value lower than a normal value, and the treated water can be drained to outside.
