A pilot-scale research on dealing with micro-polluted source water of 4.2 m 3 /h by biological aerated filter (BAF) with volcanic filler for pretreatment was carried out. Under the experimental condition of air/water ratio 1:1, and the ammonia nitrogen of raw water 1.57 to 2.72 mg/L, the ammonia nitrogen average removal rate was 95.8%, when water temperature was above 10°C; and the removal rate was still above 70%, when water temperature ranged from 5.5 to 10°C. At the same time, there was nodoi:10.5897/ajmr12.2294 fatcat:gilktbzj5rbnhnkqkr2e5ioeum
