Description
表1に示す組成のA飛灰を処理した。
表1に示す組成のB飛灰を処理した。比較例として,B飛灰500gに蒸留水を5000g加え,60min撹拌した。撹拌後,固液分離し,ろ過液の分析を行った。このろ過液の分析結果を,表4のNo.1に示す。また,実施例として,B飛灰500gを3リットルの容器に投入し,この容器内に粉砕媒体として直径6mmのスチールボール(SB)7kgと蒸留水750gを入れ,振動ミル装置により,振幅8mm,回転数を1720rpmで,飛灰を30分間粉砕した。総量5000gになるように蒸留水を加え,粉砕した飛灰を60min撹拌した。撹拌後,固液分離し,ろ過液の分析を行った。このろ過液の分析結果を,表4のNo.2に示す。また,粉砕時間を4時間とした以外はNo.2と同様に処理し,ろ過液の分析を行った。このろ過液の分析結果を,表4のNo.3に示す。また,粉砕媒体を直径3mmのジルコニアボール(ZR)とした以外はNo.2と同様に処理し,ろ過液の分析を行った。このろ過液の分析結果を,表4のNo.4に示す。本発明の実施例であるNo.2〜4のろ過液は,比較例のろ過液(No.1)に比べて,Cu,Pb,Zn,Fe,Cd,Fの溶出量がいずれも低くなった。
Claims (4)
- Al,Si,S,Pと重金属を含む飛灰を湿式処理するにあたり,予め飛灰をスチールボールを用いて粉砕することで,前記Al,Si,S,Pが機械化学的な反応を起こすことを特徴とする,飛灰の前処理方法。
- 前記スチールボールのボール径が,1〜500mmであることを特徴とする,請求項1に記載の飛灰の前処理方法。
- 予め飛灰を粉砕するに際し,水を添加することを特徴とする,請求項1または2に記載の飛灰の前処理方法。
- 飛灰には,Zn,Pb,Cu,Cd,Hg,Cr,As,B,Se,Fのうち少なくとも1つが含まれることを特徴とする,請求項1,2または3に記載の飛灰の前処理方法。
