Description
(1) 透水性が十分高く、目詰りが起こりにくいこと。これは、汚水処理能力を決定する。土地の有効利用の見地から重要な性質である。
(2) 活性アルミニウムや活性鉄等の燐酸を吸着できる化合物の含量が高いこと。これは、汚水からの燐の除去能力を決定する。
(3) アンモニア態窒素の硝化や亜硝酸化に必要な好気的な土壌層と、微生物による脱窒作用に必要な炭素源の供給が可能でしかも相対的に嫌気的な土壌層が共存し、汚水は両層を十分な速さで通過し且つ両層に十分接触浸透できる構造になっていること。これは、汚水中の汚濁物質の分解浄化だけでなく、汚水中の窒素除去能力を決定する。
(2) 積層がコンクリート容器の積み重ねであるので、汚水が通過することで土壌が流出したとしても水平の平坦は保持され、設計通りの汚水の移動となりやすい。
なお、この難透水性土壌3は予め透水性コンクリート容器2に充填しておき、これを敷き並べ積み重ねてゆけば自然に本発明装置1が構築されてゆく、という作業方法でも良いし、或いは、まず空の該容器2を平面的に敷き並べ、その後各該容器2に該土壌3を充填して一段を作る、という作業を繰り返すという方法でも良い。

Claims (6)
- リン吸着材を含む難透水性の土壌を充填した透水性コンクリート容器を、平面的に隙間なく敷き並べ、且つ敷き並べられた複数の透水性コンクリート容器の上には、一の透水性コンクリート容器を跨らせて隙間なく敷き並べ積層した浄化層が形成されているものであって、該透水性コンクリート容器は、ポーラスコンクリート製であり、且つ、壁板に対し底板の空隙率を高くしたものであることを特徴とする汚水浄化装置。
- 透水性コンクリート容器は、鉄を混合したものである請求項1記載の汚水浄化装置。
- 土壌は、炭素源を混入したものである請求項1又は2記載の汚水浄化装置。
- リン吸着材を含む難透水性の土壌を充填した、ポーラスコンクリート製であって壁板に対し底板の空隙率を高くした透水性コンクリート容器を、平面的に隙間なく敷き並べ、次いで敷き並べられた複数の透水性コンクリート容器の上に、一の透水性コンクリート容器を跨らせて隙間なく敷き並べて積層し、浄化層を形成した汚水浄化装置の上方から汚水を供給することを特徴とする汚水浄化方法。
- 透水性コンクリート容器は、鉄を混合したものである請求項4記載の汚水浄化方法。
- 土壌は、炭素源を混入したものである請求項4又は5記載の汚水浄化方法。
