発明の名称 (英語) METHOD FOR MANUFACTURING FERTILIZER FOR NATURAL WATER AND FERTILIZER FOR NATURAL WATER
発明の概要(英語) This method for manufacturing a fertilizer for natural water is characterized by including: a first dissolving step of mixing sludge ash with an acidic liquid to dissolve heavy metals and phosphorus contained in the sludge ash; a first solid-liquid separation step of separating and removing a first liquid in which the heavy metals and phosphorus are dissolved from a first solid; a reactive ionic substance adding step of adding, to the first solid, a reactive ionic substance which is an alkali metal and/or a Group II hydroxide and/or a salt; and a firing step of subjecting a composition including the first solid and the reactive ionic substance to firing. The present invention can provide: a fertilizer for natural water which effectively uses sludge ash and comprises phosphorus, silicon, and iron and has a sufficiently low content of heavy metals; and the method for manufacturing the fertilizer for natural water. In particular, the present invention can provide a fertilizer for natural water for which the dissolution rate of a fertilizer component is suitably controlled and can provide the method for manufacturing the fertilizer for natural water.
従来技術、競合技術の概要(英語) BACKGROUND ART
Global warming due to a change in the sea water temperature, sludge organic waste material is prohibited by the marine vehicle ID, the nutrient-poor sea, in particular, phosphorus and the lack of progress, are detrimental to the growth of algae. Accordingly, reduction of the amount of fishing, oysters and turban shell also higher food such as causing the decrease in the amount of collection of the aquatic, a so-called sea DESERT also progresses. Are also a significant impact on the further cultured.
Attempts to provide a nutrient source in the ocean, the slag and steel fermentation of organic waste and decomposed earth to mix, in the sea by landfilling, the growth of algae by the supply of iron and in a case that the status report (for example, see Patent Document 1.). However, this is, an object of a source of iron and, to mitigate problems caused by lack of phosphorus, can be solved cannot be achieved.
