摘要
Activated sludge microbial treatment for altering a mixture of microorganisms and nutrients and/or carrier substances in an effluent treatment, comprises the monitoring and/or control of substances supplied to the mixture, especially oxygen, carbon, nitrogen or phosphorous, or their compounds. This involves determining 1 of the following ratios in the biomass: (A) oxidisable substances to organic carbon; (B) oxidisable substance to nitrogen present in compounds or substances; (C) organic carbon to nitrogen present in compounds or substances, and (D) nitrogen present in compounds or substances to phosphorous. The amount of oxygen, carbon, nitrogen or phosphorous, or their compounds, added to the biomass is then altered depending on a known desirable ratio between these quotients.
