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.

Nitrogen is a component of many fundamental biomolecules and also participates in environmental redox chemistry. pollution serious problem. Biological nitrogen removal one the most significant issues wastewater treatment. Microbial-driven transformations are carried out through metabolic pathways. Wastewater treatment systems using microalgal-bacterial cocultures can improve nutrient efficiency interspecies synergistic interactions. However, relevant studies on metabolism microbial characteristics have not been systematically reviewed discussed. This Review comprehensively analyzes contaminants various biological composite summarizes nitrogen-metabolizing enzymes present. regulation methods involving quorum sensing genetic described, enhancing community interactions, enzyme activity, promoting electron transfer introduced detail. provides perspective improvement optimization technology analyzing increasing process performance.
