摘要： PURPOSE:To remove the harmful gases and dusts produced during incineration at a low cost by allowing the combustion gas of org. waste to react with alkaline earth metal compounds and treating the dusts and the like in the combustion gas in a steam autoclave. CONSTITUTION:The greater part of sludge incineration ashes and dusts are conducted together with the combustion waste gas of municipal refuse into an electrical dust precipitator 11 by a flue 24 and is conveyed to a granulator 10 by a conveyor 15, by which they are granulated, after which the granules are subjected to steam treatment in an autoclave 13, whereby they are made into harmless solids of high strength. On the other hand HCl, SOx entrained in the waste gas during combustion of municipal waste are allowed to catalytically react with alkaline earth metals in an incination furnace 1 and a flue 24, whereby they are chemically removed. Thereby, the harmful gases and heavy metals in the waste gas of the incineration furnace are made harmless with good efficiency.

摘要： PURPOSE:To convert cyanide-contng. solid waste into a harmless cake, by treating the waste with a steam autoclave in the presence of a calcium component and a silicate component. CONSTITUTION:Cyanide-contng. solid waste is mixed with a calcium component, e.g. slaked lime, quick lime, limestone powder or the like, and a silicate component, e.g. silica sand, silica powder, diatom earth or the like. The amounts of addition are controlled so that the calcium component will exist in an amount of about 1- 50wt% based on CaO or calculated as CaO in dried cake, while the silicate component in an amount of about 1-50wt% based on SiO2. After the addition, the mixture is agitated, blended, and then charged into a steam autoclave, where it is heated, reacted and caked. The solid waste may be preliminarily dewatered, if necessary.

摘要： PURPOSE:To make it easy to handle disposal treatment or the like by a method wherein an org. substance containing sludge added with Ca, Mg is subjected to dehydration treatment and after incinerated and molded, reacted with gaseous CO2 to solidify said sludge in an energy saving manner at low cost. CONSTITUTION:To the sludge contg. org. substances, a calcium component such as slaked lime or the like and a Mg component such as light burnt magnesia or the like or a mixture thereof are added preliminarily as a drying aid in an amount of about 0.1-100% and said sludge is treated by dehydration. This dehydrated cake is incinerated at 600-1,000 deg.C to activate Ca, Mg components. The obtained fine pulverous incineration residue is molded to an appropriate size and reacted with a gaseous CO2 of 100-0.03% concn. to be solidified. This added dehydrating aid has dehydrating capacity as well as functions effective as a solidifying agent of incineration residue. By this treating method, harmful substances such as heavy metals or the like are certainly sealed and the disposal treatment can be carried out efficiently at low cost.

摘要： PURPOSE:To obtain a solid fuel having a high calorific value and excellent ignitability, by adding a dehydrating aid to org. sludge, dehydrating the sludge, adding a difficultly volatile oil thereto and drying it in a fluidized bed with steam. CONSTITUTION:A dehydrating aid (e.g. a fiber slurry obtd. by fibrillating wastepaper) is added to org. sludge 1. The sludge is dehydrated in a highly pressing screw press dehydrator 3 to obtain a dehydrated cake 5 having a water content of 60-70%. The cake 5 is stored in a hopper 7, and a difficultly volatile oil 8 such as heavy oil or machine oil is added thereto in such a proportion as to give a ratio of Wo/Wc

摘要： PURPOSE:To prevent the elution of a noxious substance such as a heavy metal through effective treatment, by granulating and drying a substance to be dried at 100 deg.C or less throughout a drying process by revolving and fluidizing the same by the horizontally rotating action of the stirring blade of a vertical type hot air drying apparatus and hot air. CONSTITUTION:Excessive sludge (a) discharged from a sewage treating plant is treated in a precipitation basin 1 to be converted to conc. sludge (b) with water content of about 95% and an org. high-molecular flocculant is subsequently added to said sludge (b) while the treated sludge is dehydrated by a dehydrator 2 to obtain a dehydrated cake (c) with water content of 75-80%. The dehydrated cake (c) is supplied to a granulating and drying apparatus 5 by the pump of a storage tank 4 and granulated and dried at 100 deg.C or less so as to pref. reduce the water content thereof to 50% or less by combustion heat of the gasified gas (i) generated in a gassifying incinerator 6 or the holding heat of the combustion exhaust gas (j) from a baking oven 7. The obtained granulated dry substance (d) is supplied to the gasifying incinerator 6 in constant amounts by a conveyor to be gasified and burnt.

摘要： PURPOSE:To remove poisonous gas from the waste material in the combustion furnace, facilitate a solidification of the burnt ash and the fine powder dust and provide an efficient processing of the waste material under a low cost by a method wherein additive agent powder having a major constituent of calcium is directly added. CONSTITUTION:The waste material is fed from the waste material feeding port 4 of the fluidizing bed type combustion furnace 1 and burnt with air blown from the primary air blow port 2 and the secondary air flow port 3 at the top part of the fluidizing bed. Dechlorination and desulfurization are performed in the furnace with the powder additive having a major constituent of calcium blown with the secondary air, and the poisonous gas is removed. Fine powder dust contained in the combustion waste gas separated and recovered by the dust collector device 8 is mixed with the burnt ash at the ash pit 14. Then, the dust is firmly solidified at the granulating machine 15 and the autocrape 16 under an action of said additive agent contained in both materials. Therefore, it is possible to effect removal of poisonous gas generated by the combustion of the waste material, making heavy metal, etc. harmless and an efficient solidification of the combustion ash and the fine powder dust under a low cost.
