【摘要】：指出了传统河道曝气技术能在短时间内提高水体溶解氧浓度、消除河道黑臭状态,在河道水质改善方面具有一定的可行性和优越性。基于此,尝试将投加微生物工程菌法与河道曝气技术有机结合,研发了去除河水中COD和NH_3-N的长期效果更好的组合工艺。以新河支流水生态修复项目为例,研究表明:投加微生物工程菌法与河道曝气技术对水去除COD、NH_3-N与增加微生物群落的效果显著。
[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.
