Abstract
ABSTRACTA moving-bed biofilm reactor (MBBR) was used with an immobilized Pseudomonas sp. SZF15 strain in a Yu long filter (a novel bioactive carrier), which has the ability to remove nitrate and Fe (II) simultaneously. Optimum operating conditions were achieved with a nitrate removal ratio of 95.62% and an Fe (II) oxidation ratio of 88.09%. Meanwhile, high-throughput sequencing results confirmed that the immobilized Pseudomonas sp. SZF15 was not lost during the operation. This study lays the foundation for practical application of groundwater treatment.
