微生物技術(shù)：</p><p>在生物地球化學(xué)循環(huán)中，微生物充當(dāng)著*的分解者角色。在黑臭河道水體生態(tài)治理凈化中，微生物凈化能力是水體生態(tài)系統(tǒng)平衡的zui重要的一個(gè)平衡特征。微生物環(huán)境系統(tǒng)的修復(fù)，就是利用特殊生理生化功能的特異微生物在原位修復(fù)污染場(chǎng)所，應(yīng)用生物處理或生物循環(huán)過程，通過精心設(shè)計(jì)與合理應(yīng)用，阻斷或減少污染源向環(huán)境的直接釋放。</p><p>l 納米曝氣技術(shù)：</p><p>黑臭水體供氧和耗氧失衡，水體缺氧乃至厭氧條件下污染物轉(zhuǎn)化并產(chǎn)生氨氮、硫化氫、揮發(fā)性有機(jī)酸等惡臭物質(zhì)以及鐵、錳、硫化物等黑色物質(zhì)，此時(shí)溶解氧成為生態(tài)環(huán)境的限制因素。</p><p>納米生態(tài)透析技術(shù)分別獲得美國(guó)和歐洲的。該技術(shù)通過設(shè)備，將大量的納米氣泡充入水中，以增加溶氧量，從而增大生物酶活性。水體充入納米氣泡后，水體溶氧量會(huì)逐步接近飽和狀態(tài)，好氧微生物逐漸被激活，為好氧微生物與植物聯(lián)合凈化污染物提供了先決條件。納米氣泡水體生態(tài)透析工程技術(shù)能加速江河湖泊對(duì)水中污染物進(jìn)行轉(zhuǎn)移、轉(zhuǎn)化及降解的作用，從而使水體得到凈化，創(chuàng)造適宜多種生物生息繁衍的環(huán)境，重建并恢復(fù)水生態(tài)系統(tǒng)，納米技術(shù)對(duì)水體的維護(hù)治理也保證了水體中良好的生態(tài)圈。</p></div>
