Abstract

Marine anammox bacteria-based Fe(II)-driven autotrophic denitratation and anammox (MFeADA) was investigated for nitrogen removal from saline wastewater for the first time. The study demonstrated that varying influent doses of Fe(II), which participate in the Fe cycle, significantly influenced nitrogen removal performance by altering the fate of nitrite. When 50 mg/L Fe(II) was added, the nitrogen removal was mainly performed by the anammox and Fe(II)-driven autotrophic denitratation (FeAD). As the Fe(II) rose to 100-150 mg/L, the anammox, FeAD and Feammox mainly occurred. Optimal nitrogen removal efficiency, reaching 93%, was achieved at an influent Fe(II) concentration of 150 mg/L. As the Fe(II) reached 250 mg/L, however, nitrate was directly reduced to dinitrogen gas by the excessive Fe(II) through the Fe(II)-driven autotrophic denitrification (FeADN). Candidatus Scalindua (4.1%), Marinicella (5.3%) and SM1A02 (31.8%) were the dominant functional microbes. In addition, the normalized nitrate reductase abundance was about 3.1 times that of nitrite reductase, leading to the occurrence of FeAD, which achieved a stable nitrite supply for marine anammox bacteria. This novel study can promote the practical implementation of the MFeADA process in nitrogen-laden saline wastewater treatment.

期刊介绍: Water Research, along with its open access companion journal Water Research X, serves as a platform for publishing original research papers covering various aspects of the science and technology related to the anthropogenic water cycle, water quality, and its management worldwide. The audience targeted by the journal comprises biologists, chemical engineers, chemists, civil engineers, environmental engineers, limnologists, and microbiologists. The scope of the journal include: •Treatment processes for water and wastewaters (municipal, agricultural, industrial, and on-site treatment), including resource recovery and residuals management; •Urban hydrology including sewer systems, stormwater management, and green infrastructure; •Drinking water treatment and distribution; •Potable and non-potable water reuse; •Sanitation, public health, and risk assessment; •Anaerobic digestion, solid and hazardous waste management, including source characterization and the effects and control of leachates and gaseous emissions; •Contaminants (chemical, microbial, anthropogenic particles such as nanoparticles or microplastics) and related water quality sensing, monitoring, fate, and assessment; •Anthropogenic impacts on inland, tidal, coastal and urban waters, focusing on surface and ground waters, and point and non-point sources of pollution; •Environmental restoration, linked to surface water, groundwater and groundwater remediation; •Analysis of the interfaces between sediments and water, and between water and atmosphere, focusing specifically on anthropogenic impacts; •Mathematical modelling, systems analysis, machine learning, and beneficial use of big data related to the anthropogenic water cycle; •Socio-economic, policy, and regulations studies.
