Nitrogen Removal Obtained Through Heterothophic Growth in Trickling Filters.

摘要

Conventional biological treatment facilities are efficient in removing carbonaceous materials,but most remove only a small fraction of the biochemical oxygen demand exerted by nitrogen. The study investigated the use of plastic media trickling filters,and the growth kinetics of the heterotrophic bacteria on the filters,for more complete treatments. Mixed substrate environments were examined with the help of a mathematical model. Laboratory results are summarized on removal rates for glucose and ammonia-nitrogen under various conditions. Kinetic constants are tabulated.
