泡沫炭复合载体强化IFFAS工艺去除磺胺甲(口恶)唑
Carbon foam composite carriers for enhancing degradation of sulfamethoxazole in IFFAS process
摘要
Abstract
Conventional processes in municipal wastewater plants are inefficient in degrading organic micropollutants(OMPs),resulting in potential risks to the ecosystem and human health.Sulfamethoxazole(SMX)is exemplified as a typical OMPs,and novel carbon foam composite carriers are developed and implemented in the integrated floating fixed-film activated sludge(IFFAS)process.The performance of reactors is assessed and enzyme activity analysis is performed.The results show that the SMX removal performance of system is enhanced using novel carriers.Specially,during the stabilization phase,the average removal efficiency of SMX by the carbon foam composite carriers reactor(R1)reaches 99.6％at a dissolved oxygen level of(3.0±0.5)mg/L,which is increased by 32％and 106％compared with the polypropylene carrier reactor(R2)and the activated sludge reactor(R3).Meanwhile,the average removal efficiency of NH4+-N by R1 reaches 100％,rising up to 4％and 25％higher than that of R2 and R3.Compared to R2,the biofilm dehydrogenase and ammonia monooxygenase activities in R1 are increased by 80％and 41％respectively.The enzyme activities of the activated sludge in R1 is also promoted in comparison with R3.关键词
