Biological treatment method for water

摘要

A biological treatment method for water containing nitrogen and phosphorus is provided. Treatment is carried out by contacting the water with one or more substituted or unsubstituted hydrocarbon compounds each having from 1 to 6 carbon atoms in the presence of methanotrophs and/or aerobic heterotrophic bacteria under process conditions effective to reduce soluble nitrogen and soluble phosphorus levels in the water each to below about 1 mg/L.
