Elemental sulfur autotrophic partial denitrification (S0-PDN) can supply nitrite for anaerobic ammonium oxidation without an organic carbon requirement. This study aimed to evaluate the impact of high salinity on S0-PDN and investigate feasibility enhanced strategy involving addition glycine betaine (GB). The results showed that inhibited by over 60% as increased from low (0 5 g/L) (10 15 levels, even though Thiobacillus (65.9%–84.0%) was always dominant genus. reason might be suppression bioactivity. Surprisingly, GB (1 mmol/L) effectively performance under conditions g/L), resulting in a 5.1-fold increase NO3–-N conversion efficiency 3.1-fold effluent NO2–-N concentration. Metagenomics analysis revealed did not alter microbial composition. facilitated recovery nitrate capacity denitrifying bacteria with up-regulation reductase genes (by 18.1%) Sox 21.4%). However, also stimulated growth heterotrophic bacteria. Part produced reduced through electron donor. Overall, demonstrated effective approach mitigate inhibitory effects S0-PDN, which offers valuable theoretical support its application high-salinity wastewater treatment.

To solve the problems of deep nitrogen removal in wastewater treatment plants and high value utilization steel slag metallurgical industry, this work aims to prepare a sulfur/steel slag-based filter using melting method. The melt granulation method waste were main innovations work. On basis, performance media simulated actual systematically investigated. Furthermore, factors affecting studied, pilot experiments carried out. microbial community reactor was also analyzed. results showed that when mass ratio sulfur 9:1, could remove up 90% TN at room temperature, with hydraulic retention time (HRT) 5–20 h an influent 21 mg/L. In wastewater, effluent NO3−-N less than 2 mg/L, SO42− 200 pH between 6 8. from greater temperature under 8–20 8 Influence factor conducted C/N 2:1, DO 0.9–1 HRT 4 h. experiment confirmed stable below 10 compounded for practical engineering applications. Microbial analysis autotrophic denitrifying bacterial species Thiobacillus accounted 3.69% 5.55% systems, respectively. This provides novel strategy application solid field nitrate-containing treatment.
