THEORETICAL STOICHIOMETRY OF BIOLOGICAL DENITRIFICA TIONS

摘要

Biological denitrification is a phenomenon widely present in soil, water, and wastewater treatment ecosystems. Based on McCarty's half-reaction theory, taking the fraction (f_s) of electron donor coupled to cells (C_αH_βO_εN_δ) synthesis as the basic Parameter, we developed new stoichiometric equations for biological denitrifications. These denitrifications are complete Denitrifications of nitrate with, respectively, nitrate and ammonia as the nitrogen source, complete denitrification of nitrite And reduction of nitrate to nitrite with various kinds of organic carbon sources.
