摘要： PROBLEM TO BE SOLVED: To efficiently capture and remove even a trace amount of dioxins by flocculating and precipitating raw water containing dioxins, then filtering the resultant raw water through a microfiltration membrane, adding hydrogen peroxide to the wastewater filtered through the filtration membrane, and radiating ultraviolet rays while stirring and mixing the wastewater. SOLUTION: Wastewater (raw water) W1 containing dioxins is introduced into a flocculation precipitation tank 1 to precipitate and remove suspended solid with large particle size. After a prescribed sludge treatment is carried out, the precipitated suspended solid is dewatered. Then, the wastewater which is treated by precipitation treatment is filtered by a microfiltration membrane 20 in a filtration tank 2 to filter and remove suspended solid with smaller particle size and dioxins. Further, the wastewater which passes through the microfiltration membrane 20 is mixed with hydrogen peroxide and then radiated with ultraviolet rays from an ultraviolet lamp 30 in a LUV radiation water route 3 while being stirred and mixed by a stirring and mixing apparatus 40 to oxidize and decompose dioxins. Consequently, the obtained water from which dioxins are removed can be released as purified water W2 .

摘要： PURPOSE:To obtain a metal catalyst suitable for a honeycomb type catalyst low in air-flow resistance by supporting a specific cocatalyst and a specific catalyst on the surface of needle aluminum oxide precipitated on a thin metal plate. CONSTITUTION:A starting raw material A such as platinum, rhodium or palladium is dissolved in ion exchanged water to be sent to a raw material/reducing agent conditioning tank 1 and a reducing agent B is added to achieve the five pulverization of platinum, rhodium or palladium, and the resulting mixture is sent to a plating tank 2. A thin metal plate C becoming a catalyst carrier is sent to a heat treatment process 3 and a needle aluminum oxide layer is formed to the metal plate in a heated air atmosphere, and the treated metal plate is immersed in an aqueous solution prepared by adding an aluminum hydrogel to a solution obtained by dissolving a water-soluble salt of cerium, barium, strontium, zirconium, lanthanum or samarium in ion exchanged water and subsequently baked to coat the surface of the thin metal plate with oxides of the above-mentioned elements. The oxide coated thin metal plate is immersed in the plating tank 2 to be plated with a catalytic component by an electroless plating method, and dried in a drying oven 5 and baked in a baking oven 6 to form a catalyst layer on the thin metal plate.

摘要： PURPOSE:To contrive the curtailment of the amt. of a neutralizer used by providing a back washing timer to bring the pressure loss of a bug reacting tower within a narrower range of the variations than the conventional one and detecting the concn. of acidic gas at the exit of the bug reacting tower to regulate the supply amt. of an alkaline neutralizer. CONSTITUTION:There are provided a powder injecting part 2 for receiving acidic exhaust gas and an alkaline neutralizer from a supply device 3 and a bug reacting tower 5 with which the powder injecting part 2 is connected to discharge the exhaust gas deprived of dusts. A computing element 8 receives signals from acidic gas concn. meters 6 and 7 provided at the exit of the reacting tower 5 and sends a control signal to a table feeder 9 provided between the supply device 3 and the powder injecting part 2. A back washing timer 12 receives a signal from a differential manometer 10 connected between the entrance and exit of the bug reacting tower 5 and sends a control signal to a valve 11a provided between a back washing air tank 11 and the bug reacting tower 5. As a result, the amt. of the alkaline neutralizer used can be curtailed and the pressure loss of the bug reacting tower can be brought within a narrow range of the variations.

摘要： PURPOSE:To denitrate as well as desulfurize and collect dust, by injecting NH3 to an exhaust gas contg. soot and dust and NOx followed with spraying Ca(OH)2 with a powder of V2O5-carrying Al2O3 or TiO2 and capturing soot and dust powders by a ceramic filter. CONSTITUTION:NH3 is injected from a nozzle 5 to an exhaust gas from a diesel engine contg. NOx, SOx, and soot and dust and then a denitration catalyst powder of V2O5-carrying gamma-Al2O3 or anatase-type TiO2 with Ca(OH)2 is sprayed to the gas by a blower 4 of a powder supplier 3. And then, simultaneously with reduction of Nox, SOx is oxidized to SO3 and neutralized with Ca(OH)2. Then, the denitration catalyst powder, Ca(OH)2 powder, and soot and dust are captured by a ceramic filter 2 and discharged as collected ashes 6 and meanwhile the resulting purified gas is discharged through a waste heat recovery installation 7.

摘要： PURPOSE:To accelerate the neutralizing reaction of slaked lime with SOX by mixing the powder of vanadium oxide into slaked lime and providing a ceramic filter in the post-stream of exhaust gas in the exhaust gas desulfurization by means of the dry method. CONSTITUTION:Exhaust gas containing SOX in a diesel engine 1 passes through a ceramic filter 2 and an equipment 6 for exhaust heat recover and the like downstream to be discharged out into atmosphere. The mixed power of slaked lime and V2O3 is transferred from a powder feeder 3 to an air blower 4 and getted out into an exhaust tube post-stream the diesel engine 1. The jetted mixed powder is dispersed into the exhuast gas quickly while the slaked lime is neutralization reacting with SOX, and V2O5 turn SO2 into SO3, and formed SO3 is neutralization reacted with the slaked lime to be guided into the ceramic filter 2. Then, when the exhaust passes through a layer collected and piled by the filter 2, the slaked lime nor yet reacted is further neutralization reacted with SOX.
