摘要： PROBLEM TO BE SOLVED: To activate useful bacteria and to improve processing efficiency in a processing material added to org. waste, held at weak alkalinity and biologically fermenting the waste by forming the material mainly with the coal ash with the hydraulic modulus and Blaine specific surface specified. SOLUTION: This org. waste processing material is used to biologically treating the org. waste such as garbage and org. sludge without putrefying the waste while suppressing the development of rancidity. Namely, the material is formed mainly with the coal ash having 0.02-0.20 hydraulic modulus and >=2400cm /g Blaine specific surface. The bacteria useful in fermentation can be incorporated into the material, the wooden powder or plant remainder can be incorporated as a carbon source, and further a porous powder can be incorporated as the imbedding material for useful bacteria and a deodorant. Meanwhile, >=3 pts.wt. of the processing material is added to 100 pts.wt. of the org. waste, and hence the org. waste is made weakly alkaline and biologically fermented.

摘要： PROBLEM TO BE SOLVED: To improve deodorizing effect of a deodorant for sludge, etc., by making the deodorant contain powder containing at least aluminum sulfate, coal ash, zeolite, etc. SOLUTION: Powder containing at least aluminum sulfate, coal ash, and zeolite are used for this deodorant. Fly ash, etc., with particle diameter lower than about 5 mm can be used as coal ash regardless of combustion systems. Coal ash with pH 5.0-8.0 for 30 wt.% slurry and BET specific surface area higher than 1.5 m /g is used. Further, use of powder containing aluminum sulfate and zeolite are considered. As aluminum sulfate, a single salt or a double salt and a hydrates thereof can be used. Those are hydrolysed by water in sludge to give acidity and demonstrate synergic effect cooperating with adsorption action of coal ash and zeolite. Thus deodorization of sludge can be effectively carried out.

摘要： PROBLEM TO BE SOLVED: To efficiently obtain a foamed glass hardly having strain or deformation and keeping an expected dimension by dividing a raw material to be fired into plural blocks, laying the blocks with a gap having specific dimensions between the block and the peripheral wall of a vessel and between one block and the others and firing to integrate each of blocks at the time of obtaining the foamed glass by charging the raw material to be fired to the vessel, firing and foaming it. SOLUTION: The raw material to be fired (e.g. one obtained by adding CaCO3 as a foaming agent and bentonite as a binder into a bottle glass cullet of a glass raw material and crushing them) is formed to make plural blocks 20a-20d, the blocks 20a-20d are laid by providing the gap slightly shorter than the increase of expanding length due to the firing, preferably having the length 95-95.5% of the increase of the expanding length, and are fired to integrate each of blocks 20a-20d. An inner cap is preferably placed on the raw material and the raw material is fired with the gravity of the inner cap loaded.

摘要： PROBLEM TO BE SOLVED: To provide a waste bag which contributes to improve the performance of the waste bag and whose incineration ash is prevented from becoming high alkali by containing dolomite at the specific ratio by weight. SOLUTION: A waste bag containing dolomite, at least, by 0.5% in the ratio by weight is useful for producing no pollution. The dolomite decomposes at a lower temperature compared with calcium carbonate and has superior reactivity so that it is expected to produce neutralization effect at the quantity less than the calcium carbonate. As a result, the incineration ash is prevented from becoming high alkali compared with calcium hydroxide or calcium carbonate whose major components are Cab. Both baked and unbaked dolomites may be used, however, one containing it 0.5% or less in the ratio by weight exhibits less effects. The incinerated ash and combustible waste are pressurized and solidified so that the solid fuel without generating malodor is provided.

摘要： PROBLEM TO BE SOLVED: To efficiently treat a fresh-water based dredged mud and to effectively utilize the mud as a ceramic starting material, soil conditioner, fertilizer, etc., by mixing quicklime having a specified activation coefficient and average BET specific surface area respectively with a fresh-water region mud piled at a bottom part of lake, river or reservoir, etc. SOLUTION: At the time of treating the mud piled at the bottom part of the fresh-water region such as lake, river, water passage or reservoir, quicklime having >=100ml activation coefficient and >=1.0m /g average BET specific surface area is used as the treating material and the quicklime is mixed into the mud in the fresh-water region. At this time, a collected mud is dehydrated to reduce water content till 60-100wt.% since a large amount of water content is incorporated into the collected mud. The quicklime is excellent in hydration reactivity, and the dredged mud is efficiently dried by a heat generated at the time of hydrating the quicklime by adding and mixing the quicklime into a cake-shaped dredged mud. And the quicklime is very liable to connect with a eutrophic component consisting essentially of phosphorus and nitrogen and these component is appropriately immobilized.
