摘要：
Through the removal effects of the anoxic/oxic (A/O) biological filtration technology on organic matters, nitrogen and phosphorus, the advanced treatment for secondary effluent of municipal wastewater was analytically characterized by means of filter material selection and natural biofilm start-up. The results show that the composite slag has the best adsorbing effects on ammonia nitrogen and phosphorus, reaching 57% and 32.2%, respectively; as the natural biofilm start-up is smoothly implemented, the removal rate of ammonia nitrogen reaches over 60% in the first phase and over 96% in the second phase. This study provides a reference for the advanced treatment for secondary effluent of municipal wastewater.
