Phthalocyan ine wastewater has strong acidity,hish NH3一N concentration an d high Cu2+concentration,an d therefore hard to treat. It iS developed to treat phthalocyan ine wastewater after physicochemical treatment by A/o bio-contact oxidation.The results show that the increase of refluence ratio iS favorable for the transformation of organic nitrogen. nitrification and denitrification the augment of HRT could increase the removal eficiency of decarbonization and accelerate the nitrification. When the COD iS 500 mg/L, the refluence ratio iS 300% and HRT is 50 h,the removal eficiency of COD&,NH3一N and TKN Can reach 91.o%,98.8% an d 98.铴,respectively.
