| description | Organic matter and ammonia-nitrogen pollution are the research focuses of sewage purification. PMMA fiber biofilm carriers were prepared using the electrospinning technique and compared with nonwoven fiber biofilm carriers in purification experiments. The two biofilm carriers are bacteria-cultured for several days, and the chemical oxygen demand (COD) and ammonia nitrogen (NH3–N) of the sewage are tested and analyzed. The results showed that after four days of purification, the COD concentration removal rate of the non-woven fiber biofilm group reached 77.89%, and the COD removal rate of the PMMA fiber biofilm group reached 82.70%. After six days of purification, the NH3–N concentration in the non-woven fiber biofilm group did not decrease but increased, from the original 7.64 to 8.74 mg/l, with an increase rate of 13.87%. The NH3–N concentration in the PMMA fiber biofilm group decreased from the original 7.62 to 6.22 mg/l, with a removal rate of 13.87%. It can be seen that the PMMA fiber biofilm carrier has more advantages in the reduction of COD and NH3–N in organic wastewater. |
