“…Dujų absorbcija naudinga atskiriant dujinius mišinius, šalinant priemaišas ir gali atstatyti vertingus cheminius junginius. Šiuo metu auga ekologiškų ir aplinkai palankių technologijų poreikis, dėl to didėja susidomėjimas biologinėmis alternatyvomis (Morral et al, 2020). Keletas biologiniais procesais paremtų konfigūracijų (pvz., biofiltrai, bioskruberiai) buvo naudojama LOJ šalinti iš oro įvairiomis sąlygomis (Bravo et al, 2017).…”

“…12 Biological processes, including trickling filters, fluidized bed reactors, and biological contactors, are widely accepted for the treatment of wastewaters containing ammonia and organic pollutants. 13 However, the biochemical methods often require a large space for installation and produce waste sludge. 14 Electro-oxidation of ammonia as a good alternative to present methods has several advantages, such as a small reaction scale, minimal sludge generation, and rapid startup.…”

The nickel (Ni) and copper (Cu) oxides decorated with Pt nanoparticles (Pt NPs) were synthesized via electrodeposition for direct ammonia electro-oxidation. Voltammetry results revealed the reversible oxidation states of the transition metals as mediating the electron transfer of nitrogen species. Cu and Ni oxides showed catalytic ammonia oxidation at working potentials of +0.23 V and +1.1 V (vs Hg/HgO), respectively, and the peak current was significantly improved by Pt modification. In a constant current mode, the two-electrode electrolysis determined the efficiency of NH 3 conversion to NO 3 − and N 2 . At a current density of 1.5 mA cm −2 , the promising removal efficiency of NH 3 (>90%) on Cu and Ni oxides was attributed to the high electrochemically effective surface area (A ECSA ). The reaction mechanism of NH 3 oxidation and production of different nitrogen species were evaluated via a steady-state approach. The decoration of Pt NPs onto PtM/G and a low applied current favored ammonia conversion more to nitrogen gas than the monometal electrode did. Pt sites enhanced the dehydrogenation of NH 3 , thus moderately increasing the N 2 selectivity up to 60% on the PtCu/G electrode for an initial NH 3 of 50 mg-N L −1 .

Biofilters have been broadly applied to degrade the odorous gases from industrial emissions. A industrial scale biofilter was set up to treat the odorous gases. To explore biofilter potentials, the microbial community structure and function must be well defined. Using of improved biofilter, the differences in microbial community structures and functions in biofilters before and after treatment were investigated by metagenomic analysis. Odorous gases have the potential to alter the microbial community structure in the sludge of biofilter. A total of 90,016 genes assigned into various functional metabolic pathways were identified. In the improved biofilter, the dominant phyla were Proteobacteria, Planctomycetes, and Chloroflexi, and the dominant genera were Thioalkalivibrio, Thauera, and Pseudomonas. Several xenobiotic biodegradation-related pathways showed significant changes during the treatment process. Compared with the original biofilter, Thermotogae and Crenarchaeota phyla were significantly enriched in the improved biofilter, suggesting their important role in nitrogen-fixing. Furthermore, several nitrogen metabolic pathway-related genes, such as nirA and nifA, and sulfur metabolic pathway-related genes, such as fccB and phsA, were considered to be efficient genes that were involved in removing odorous gases. Our findings can be used for improving the efficiency of biofilter and helping the industrial enterprises to reduce the emission of waste gases.
