采用钢铁转炉渣(SCS)制成的电生物颗粒电极(EPE)作为颗粒电极，在扩大阳极电生物反应器(EAEB)中处理罗丹明B(RhB)废水，考察了其净化性能和微生物群落。结果表明：(1)EAEB反应器对RhB、COD和NH4+-N的平均去除效率分别为91.68%、87.63%和90.54%，比曝气生物滤池分别提高了59.86%、20.48%和14.22%；(2)EAEB反应器同时去除RhB、COD和NH4+-N的最佳电流强度(CI)为1.00A；(3)EAEB中的主要细菌群落为嗜甲酸菌、气单胞菌、假单胞菌、假单胞菌和动物群。因此，利用转炉渣(SCS)生产EPE的EAEB反应器适合同时去除RhB、COD和NH4+-N。
Electro-biological particle electrode (EPE) made from steel converter slag (SCS) was used as a particle electrode in an enlarged anode electric biological (EAEB) reactor for Rhodamine B (RhB) wastewater treatment, and its purification performance and microbial community were examined. The results revealed that (1) the EAEB reactor showed much higher average removal rates of RhB, COD and NH4+-N, i.e. 91.68%, 87.63%, and 90.54%, which meant an increase by 59.86%, 20.48%, and 14.22%, respectively, compared with BAF; (2) The optimum current intensity (CI) for simultaneously removing RhB, COD and NH4+-N in the EAEB reactor was at 1.00 A; and (3)Methylophilus, Aeromonas, Pseudomonas, PelomonasandZoogloeaaccounted for the main bacterial community in EAEB. Therefore, the EAEB reactor with EPE produced from steel converter slag (SCS) was suitable to simultaneously remove RhB, COD and NH4+-N.
