Abstract


The MABFT high-density biological enrichment special denitrification process (modified aeration biological fluidized tank) is applied to the high ammonia nitrogen wastewater treatment project formed by digital printing. The results showed that when the influent NH3-N ≤ 300 mg/L, the effluent NH3-N ≤ 10mg/L treated by MABFT technology, the average removal rate of ammonia nitrogen was as high as 98.9%, and all indexes in effluent would meet the requirements of the People's Republic of China’s Discharge standards of water pollutants for dyeing and finishing of textile industry for new plants. Providing reference for the treatment of similar high ammonia wastewater.
