Description
ホウ酸試薬、塩酸(濃度35〜36%)、水酸化ナトリウムを用いてホウ素濃度B:500mg/L、塩化物イオン濃度0〜10,000mg/Lの模擬排水を調整した。これに、表1に示す水処理剤を添加し、以下に記載する方法でホウ素水処理試験を実施した。
(1)試薬で調整したホウ素濃度500mg/Lの模擬排水を500mlビーカーに200ml分取し、所定配合の水処理剤を添加し、ホウ素等の水処理能力を評価する。
(4)吸引ろ過装置にろ紙(5C)をセットし、溶液を真空ろ過する。(pH測定)
(5)ろ液を使用し、ICPを用いてホウ素濃度を測定する。また、排水中に含有する場合はセレン濃度をICPにて測定、フッ素濃度をガラス電極で測定する。
ここでは、ホウ素濃度95.1mg/L、フッ素濃度31.8mg/Lの窯業における排水の処理を検討する。排水中の両成分を一律排水基準値以下まで処理することが、水処理の目的である。(ホウ素:10mg/L以下、フッ素:8mg/L)この排水に以下の水処理剤を粉末として添加し、前記の方法で水処理試験を行った。
(実施例7)この排水に表1に記載した水処理剤を1.5質量%添加した。この結果は表3のとおりとなった。
ここでは、排煙脱硫排水の処理例を示す。石炭火力発電所から採取した脱硫排水にホウ酸試薬を添加し、ホウ素濃度をおよそ500mg/Lに調整を行った。調整後の排水の特性は以下のとおりであった。この排水に表1、実施例6に示した水処理剤を1.7質量%添加して、前記と同様の方法で水処理試験を実施した。この結果を表3に示す。
(排煙脱硫排水の特性)
・排水組成等:Ca:1210mg/l、Cl:3850mg/L、SO4:2510mg/L等、pH7.5
・有害イオン濃度:ホウ素濃度491mg/L(原水:185mg/L)、フッ素16.4mg/L、全セレン:0.55mg/L
表3、実施例8の結果に示すとおり本発明の水処理剤により、高濃度のホウ素を含有する排水を、全成分とも海域への排水基準以下まで極めて良好に処理することができた。また、この処理におけるホウ素の除去能力は20mg/gと極めて高い水準となった。(排水基準(海域):ホウ素:230mg/L、フッ素:15mg/L、全セレン:0.30mg/L)
ここで使用した二硫化鉄粉(黄鉄鉱粉)は、中国製粉砕品であり粒度100メッシュ以下、組成はFe:48.7質量%、S:45.9質量%、SiO2:4.1質量%の高純度なものである。また、生石灰、硫酸アルミニウムは前記と同じものを使用した。

- さらに消石灰を添加することを特徴とする請求項1記載の水処理方法。
- さらに鉄化合物を添加し、セレンを除去することを特徴とする請求項1又は2記載の水処理方法。
- 生石灰及び消石灰を粉末として排水に添加することを特徴とする請求項2記載の水処理方法。
