【摘要】：指出了傳統(tǒng)河道曝氣技術能在短時間內(nèi)提高水體溶解氧濃度、消除河道黑臭狀態(tài),在河道水質改善方面具有一定的可行性和優(yōu)越性�；诖�,嘗試將投加微生物工程菌法與河道曝氣技術有機結合,研發(fā)了去除河水中COD和NH_3-N的長期效果更好的組合工藝。以新河支流水生態(tài)修復項目為例,研究表明:投加微生物工程菌法與河道曝氣技術對水去除COD、NH_3-N與增加微生物群落的效果顯著。
[Abstract]:It is pointed out that the traditional river aeration technology can increase the dissolved oxygen concentration in the water body in a short time, eliminate the black and smelly state of the river, and has certain feasibility and superiority in the improvement of river water quality. Based on this, the combination process of removing COD and NH_3-N from river water was developed by organically combining the addition of microbial engineering bacteria with river aeration technology. Taking the ecological restoration project of Xinhe branch as an example, the results show that the effect of adding microbial engineering bacteria and river aeration technology on water removal of COD,NH_3-N and increasing microbial community is remarkable.
