Abstract

本研究では, 停滞・閉鎖性水域に適用可能な新たな水環境修復技術の確立を目指し, Mg-Al-Cl型ハイドロタルサイト化合物と発泡ガラス, 専用の浮力体を複合化した浮島型リン吸着コンクリートの利用性について基礎的検討を行った.実験には停滞水域の一種である島根県松江市の堀川を選定し, 供試体を約3ヶ月設置した.その結果, 浮島型リン吸着コンクリートは水環境中に負荷を与える物質を溶出しないこと, 物理・化学的なリン除去能力を発揮することがわかった.また, 供試体上層部に植栽した植物の生長量を評価した結果, 植物の生長による生物学的な栄養塩類の除去効果も確認できた.さらに, 波浪などの外力に対して耐えられる安定した構造であることを確認した.以上の結果から, 浮島型リン吸着コンクリートは停滞・閉鎖性水域の新たな水環境修復資材として利用可能であることが明らかとなった.

The utility of floatable phosphorous adsorption concrete, developed for a new restoration technique on the environmental water such as closed and stagnant water area, was verified fundamentally in this research. This material was composed of Mg-Al-Cl forms a hydrotalcite compound, foamed glass, and special buoyant body. Horikawa, one kind of stagnant water in Matsue city, was selected for the experimental site, and put these materials into this river for three months. As for the fundamental experiments on this material, it was confirmed that any environmental pollutants haven't dissolved into the water, and this material has the ability of phosphorus removal due to the chemical and physical reactions. Moreover, one kind of plant was vegetated at the upper surface of this material. The growth of plants was evaluated and it was confirmed that vegetated plant had worked as the biological removal of nutrients. Furthermore, it was revealed that this material was stable against the external force, such as wind and wave forces. Therefore, this material, floatable phosphorous adsorption concrete could be considered to be useful as a new environmental restoration material in stagnant and closed water area.
