城市黑臭水体治理中水生植物及微生物对水体净化作用的试验

Experimental Study on Purification of Water Body by Aquatic Plants and Microorganisms in the Treatment of Urban Malodorous Black River

河流水体中溶解氧的高低,是衡量水体污染程度的重要指标,也是衡量水质的综合指标。在对河流水体充氧曝气的基础上,保持水体中的溶解氧充足,本研究采用不同的试验参数观察河道水质的氨氮消解过程与效果,以探究水生植物及水中微生物在黑臭水体治理过程中对水体净化作用的影响。

The level of dissolved oxygen in river water is not only an important index to measure the water pollution level, but also a comprehensive index to measure the water quality. On the basis of aeration and oxygenation of the river water, the dissolved oxygen in the water was kept adequate, and different experimental parameters were used to observe the process and effect of ammonia-nitrogen digestion in the river water quality, in order to explore the effect of aquatic plants and microorganisms on the purification of malodorous black river.
