Aniline containing phenol wastewater treatment process for acetonitrile production

by:Deyuan      2020-08-31
Commonly used methods for removal of high concentration phenol with physical method, chemical method and physicochemical method, aniline containing phenol wastewater treatment process for acetonitrile production belongs to the typical solvent extraction process.
magnesium ammonium phosphate is a kind of sediment (ammonia nitrogen in wastewater can be converted to MgNH4PO4·6H2O) A chemical treatment to remove ammonia nitrogen. Precipitation generated due to the MAP method is a kind of slow release fertilizer, and the basic do not absorb metal ions and other impurities, can make the ammonia nitrogen in wastewater into. Therefore, the MAP method is a kind of green environmental protection method of removal of high concentration of ammonia nitrogen in the wastewater.
aniline acetonitrile production wastewater is the dye effluent discharges of industrial wastewater, it has complex component, high COD, high ammonia nitrogen and high phenol characteristics, is a kind of high concentration organic wastewater difficult biodegradation. There are a few study the biochemical method is adopted for processing. Because of the wastewater containing high concentration of ammonia nitrogen of phenol, and the decomposition of organic nitrogen to release ammonia nitrogen in water, if USES the biochemical treatment, ammonia nitrogen must be the concentration of the biochemical system can tolerate.
when extracting magnesium ammonium phosphate is studied through experiment of aniline acetonitrile in the production of high concentration of ammonia nitrogen in the wastewater treatment effect and the reaction conditions, similar sums up the aniline containing phenol wastewater treatment process for acetonitrile production, to remove phenol in waste water provides a possible way.
