SLUDGE CLARIFIER

PROBLEM TO BE SOLVED: To provide a sludge clarifier for performing aeration of sludge for clarifying the sludge, over a certain period.SOLUTION: A sludge clarifier 1 clarifies sludge by: mixing and dispersing solid objects 2 which generate oxygen by reaction with water to a solidification material 3 which is decomposed by reaction with water; performing granulation and solidification so that the solid objects 2 are included in the solidification material 3; and covering the solid objects 2 with the solidification material 3, therefore the period for generating oxygen is extended, and a natural field which is a place to which the sludge clarifier is added can maintain an aerobic condition for a long period and the sludge can be purified. 【課題】或る期間に亙って、ヘドロを好気化し、ヘドロを浄化する方法の提供。【解決手段】水と反応して分解する固化材３に水と反応して酸素を発生する固形物２を混合分散し、固化材３の中に固形物２を含む様に造粒固化し、固形物２を固化材３で覆うことにより、酸素を発生させる時間を長くし、添加した場所の自然界は長期間好気条件が維持され、ヘドロが浄化できるヘドロ浄化剤１。【選択図】図１
