| Abstract: | Phthalocynine blue pigment wastewater has strong acidity,high copper concentration and high ammonia nitrogen concentration,and therefore is hard for treatment.Copper recovery is fulfilled by using iron powder replacement.Removal of ammonia nicrogen in wastewater is done by using chemical precipitant magnesium salt and phosphate,with the useful outcome of compounds fertilizer MgNH4PO4.Thus,both environment and economy can be benefited. |

| Keywords: | phthalocyanine blue pigmext replacement ammonia nitrogen magnesium ammonium phosphate chemical procipitation |
