摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for evaluating the water quality of a river, by each of which a quantitative variation of the water quality in which the water quality of the actual river is reflected faithfully can be predicted and the effect of a water purifying material or the like in the actual river can be grasped quantitatively. SOLUTION: This method for evaluating the water quality of the river comprises the steps of: filtering the water taken from the river by a screen having 40-100 μm mesh; throwing the filtered water in a closed-loop circulation type horizontal water route 1; circulating the thrown water at 5-20 cm/second flow velocity by a circulation pump 2; sampling the circulating water periodically; measuring indexes of nutritive salt and/or organic matter in the sampled water and; predicting the variation of the water quality of the actual river from the variations of these indexes. Otherwise, this method for evaluating the water quality of the river comprises the steps of: putting the water purifying material or the like in the circulation type horizontal water route; measuring indexes of nutritive salt and/or organic matter; calculating a difference of each of the indexes between when the water purifying material or the like is used and when the water purifying material or the like is not used and; predicting the variation of the water quality of the actual river from the calculated differences.

摘要： PROBLEM TO BE SOLVED: To provide novel slaked lime with a large specific surface area, which shows an excellent performance at transport, is suitable for removing acidic substances from combustion exhaust gas of wastes etc., has characteristics inherent in calcium hydroxide with a large specific surface area, such as high reactivity with acid gas and reduced generation of fly ash or dust and avoids troubles concerning discharge from storage tanks and occlusion of piping. SOLUTION: The slaked lime with a large specific surface area essentially comprises calcium hydroxide and has a nitrogen adsorption specific surface area of ≥35 m 2 /g and an average particle size of ≥75 μm for particles within the range of 40-200 μm and contains ≥45 wt.% particles within the range of 40-200 μm. The coarse particles of the slaked lime have small contact area with other particles when they contact or collide with other particles in the piping etc., which results in little coagulation or growth, and their large mass and inertia force prevent their deposition on interior of the piping etc. Therefore, the obtained slaked lime with a large specific surface area shows an excellent performance at transport.
