摘　　要：采用生物法处理初期雨水,探究了在污泥中添加Fe_(2)O_(3)纳米改性蜂巢石对初期雨水处理性能、关键酶活性和污泥微生物群落结构的变化。结果表明,对照组反应器对NH_(4)^(+)-N、COD_(Cr)、TP的去除率分别为75%,65%和67%,投加Fe_(2)O_(3)纳米改性蜂巢石后,去除率分别提升了9%,10%,13%。Fe_(2)O_(3)纳米改性蜂巢石提升了脱氢酶和细胞色素C的活性,使得微生物间电子转移和氧化能力得到提升,进而增强了对初期雨水的降解能力和处理效率。高通量测序结果显示,Fe_(2)O_(3)纳米改性蜂巢石促进了Proteobacteria、Bacteroidota和Patescibacteria的富集,这些菌群表现出较强的氨氮和COD降解能力,其中Proteobacteria对氮、磷的去除有良好的效果。微生物群落之间的协同作用提升了雨水中污染物的去除效果。The biological method was used to treat first flush stormwater.The effects of adding Fe_(2)O_(3)nanomodified pumice to sludge,and detect its treatment performance,key enzyme activity and sludge microbial community structure of first flush stormwater.The results indicate that the removal rate of NH_(4)^(+)-N,COD_(Cr),and TP in the control group reactors were 75%,65%,67%respectively.After adding Fe_(2)O_(3)nanomodified pumice,the removal rates increased by 9%,10%,and 13%respectively.The Fe_(2)O_(3)nanomodified pumice enhanced the activity of dehydrogenase and cytochrome C,resulting in improved electron transfer and oxidation capabilities among microorganisms.Consequently,this strengthened the degradation ability and treatment efficiency of the first flush stormwater.High-throughput sequencing results showed that Fe_(2)O_(3)nanomodified pumice promoted the enrichment of Proteobacteria,Bacteroidota,and Patescibacteria.These bacterial groups exhibited strong capabilities in ammonia nitrogen and COD degradation,with Proteobacteria showing good efficiency in nitrogen and phosphorus removal.The synergistic interactions among microbial communities further enhanced the removal efficiency of pollutants in first flush stormwater.
