The invention relates to a high organic
nitrogen concentration
wastewater treatment. The high organic
nitrogen concentration
wastewater treatment comprises performing ozonation to remove and convert apart of organic
nitrogen and organic matters, and through an
ozone destruction tank, removing
ozone residue in water to reduce damage of
ozone to microorganisms; through
anaerobic treatment, removingorganic nitrogen and organic matters in converted water and meanwhile performing
denitrification reaction on
nitrate nitrogen brought back by
reflux to thoroughly eliminate nitrogen in the water; through a packing type MBR (
membrane bioreactor) unit, thoroughly decomposing the organic matters, converting a major part of
ammonia nitrogen through
nitrification into
nitrate nitrogen and
nitrite nitrogen, performing ammonization reaction on a small part of the organic nitrogen, and meanwhile, forming an anaerobic environment inside packing biomembranes for
denitrification reaction to further reduce
ammonia in discharged water. The high organic nitrogen concentration
wastewater treatment is practical and effective, can effectively remove nitrogen, COD (
chemical oxygen demand) and the like in high organic nitrogen concentration wastewater and achieves up-to-standard
discharge of the wastewater, thereby achieving high environmental benefits and a broad application prospect.
