Phosphorus Removal with Hydrotalcite Compound

open access: yesJournal of the Japan Society of Waste Management Experts, 2002
高濃度にリンを含むし尿処理水からリンを除去する方法として, ハイドロタルサイト系化合物 (HTAL) を用いた吸着 (イオン交換) 法について検討を行った。HTALは, pH5.5以上で安定したリン除去能を示し, 吸着等温線はLangmuir型の修正式で近似することができた。HTALの飽和吸着容量は50.8mg-P/gであり, 造粒したHTALでの飽和吸着量はわずかに低い程度であった。1molのオルトリンは, 2molのCl-イオンと交換されたが, 脱炭酸を行わない場合, 3molのCl-イオンと交換された。共存イオンとしての塩素イオンは1, 000mg-Cl/L, 硫酸イオンは200mg-S/Lまでの範囲では, 影響が小さかった。炭酸イオンは相対的に影響が大きく ...
