The Effect of Aeration on the Purification Rate Using Microporous Aeration-Ecological Floating Island Technology

To explore the purification effects of microporous aeration-ecological floating island technology, two groups of floating island treatment facilities are adopted in the experiment under aeration conditions of 40 L/s and 80 L/s to find out the relations between pollutant removal and aeration. The following conclusions can be drawn from this paper: microporous aeration-ecological floating island technology has achieved remarkable effect in removing NH4+ and COD under high aeration conditions, but performed badly in removing NO3− and P. In actual practices, aeration can be adjusted based on the water quality conditions, costs and purification cycle of the water system to achieve optimal effect.
