Experiment and analysis of the biological filter by falling water aeration

摘要

Experiments of of the biological filter by falling water aeration show that the removal rate of CODcr is 66.9%, of NH3-N is 64.5%, of TP is 48%.The ideal effect can be obtained if the water is 100% circulation processing. Combination process around the core that is biological filter by falling water aeration should be good for mountain town water pollution control by this paper.
