在國民經濟快速增長,人民群眾生活水平顯著提高的情況下,經過不懈努力,環境保護工作取得很大進展,但水環境嚴峻形勢總體上仍沒有根本改變。主要是污染物排放量超過水環境承載能力,河道水污染,湖泊富營養化,生態破壞嚴重,生物多樣性減少,生態系統功能退化,制約經濟社會發展,危害人民健康,影響社會和環境安全。

水體修復的概念和原則

水體修復:万博体彩 除了依靠水生生態系統本身的自適應、自組織、自調節能力以外,采取人工的物理、化學和生物的方法,使水體恢復到原有的生態功能的過程。


原則:簡言之,經濟上可行和技術上可行。

水體生物修復技術

水體的生物修復技術是新近發展起來的一項清潔環境的低投資、高效益,便于應用、發展潛力巨大的新興技術,它利用特定生物(主要是微生物)對水體中污染物的吸收、轉化或降解,達到減緩或最終消除水體污染、恢復水體生態功能的生物措施。


從生物的選擇和培養應用上來分主要包括直接投加微生物技術、培養微生物技術和高等生物修復技術等。

高等生物修復技術

由于水生植物對污染水體有一定的凈化能力,因此,在污染水體中種植對污染物吸收能力強且耐受性好的植物, 能夠對水體中的污染物進行吸附、吸收、富集和降解等作用, 從而實現將水體中污染物的去除或固定, 達到水體修復的目的。植物對污染物可通過根系吸收,也可以直接經莖、葉等器官的體表吸收。常用于水體修復的植物有鳳眼蓮(即水葫蘆)、蘆葦、香蒲、喜旱蓮子草、水芹、浮萍、菱、菖蒲等等


植物修復不足之處:万博体彩一些植物在富營養化水體中生長迅速,若收集不及時,可降低水體中的溶解氧,加劇水體富營養化,產生負面效應。
