Abstract
【解決手段】塩化第二鉄などの無機凝集剤を第1急速撹拌槽18に添加し、有機高分子凝集剤を第2急速撹拌槽26に添加し、フロック形成槽34でフロック形成し、沈殿槽38でフロックを沈殿分離する。この沈殿処理水を砂ろ過器44でろ過処理して、その処理水をさらに活性炭吸着塔46で吸着処理することで、有機ヒ素化合物を低減する。
【選択図】図1
Description
まず、ジャーテストにより有機ヒ素化合物が除去できる条件を確認した。フェニルアルシン酸の混入した実際の地下水を用いてジャーテストを行った。試料水水質の分析結果を表1に示す。全ヒ素と有機ヒ素の分析は以下の通りである。まず試料水を加熱酸化処理して有機物を分解して、全て無機ヒ素とし、これをICP−MSで定量して全ヒ素とする。一方試料水を高速液クロマト分離装置で無機ヒ素である3価と5価のヒ素を分離し、この分離水中の無機ヒ素をICP−MSで定量した。全ヒ素から無機ヒ素を差し引いたものが有機ヒ素である。以上の方法によって定量した全ヒ素は1.14mg/Lで、無機ヒ素は定量下限値0.001mg/L以下であり、全ヒ素のうち、ほぼすべてが有機ヒ素化合物であった。
(i)次亜塩素酸ナトリウム(前塩素)(塩鉄注入前に注入し10分撹拌混合)
(ii)有機高分子(オルガノ製WGN−120(商品名)、ポリアクリルアミド)(塩鉄注入急速撹拌後、緩速撹拌開始時に注入)
次に、有機ヒ素化合物除去装置による通水実験を行った。装置のフローを図1に示す。装置は10m3/hの能力で、沈澱池の表面負荷率は5cm/min(3.0m/h)、ろ過池のろ過速度はLV=10.4cm/min(150m/d)、活性炭吸着塔のろ過速度LV=20.8cm/min(300m/d)で空筒接触時間SV=8.3h-1である。着水井にて硫酸によりpHを7.0に調整した。無機凝集剤は塩化第二鉄を使用し、原水中有機ヒ素濃度×0.22mmol−Fe/L添加した。凝集助剤にはノニオン性のポリアクリルアミドを(塩化第二鉄添加濃度×0.004+0.2)mg/L添加した。また砂ろ過器の前に塩素3.0mg/Lを添加した。
