Direct sewage discharge could cause copious numbers of serious and irreversible harm to the environment. This study investigated the impacts of treated and raw sewage on the river ecosystem. Through our analysis, sewage carried various nutrients into the river, leading to changes in the microbial community in the river and reducing the diversity and richness of bacteria. The relative abundances of Hydrogenophaga, Thauera, Planctomyces, Zoogloea, and Pseudomonas boosted from 0.25, 0.01, 0.00, 0.05, and 0.08% to 3.33, 3.43, 0.02, 6.28, and 2.69%, before and after raw sewage discharge, respectively. The gene abundance of pathogenic bacteria significantly increased after raw sewage discharge. For instance, the gene abundance of Vibrio, Helicobacter, Tuberculosis, and Staphylococcus augmented from 4055, 3797, 13,545, 33 reads at Site-1 to 23,556, 13,163, 19,887, 734 reads at Site-2, respectively. In addition, according to the redundancy analysis (RDA), the infectious pathogens were positively related to the environmental parameters, in which COD showed the highest positive correlation with Mycobacterium tuberculosis. Additionally, river self-purification may contribute to improving water quality and reducing pathogenicity. The outcomes of this study showed that direct discharge brought pathogens and changed microbial community structure of the river.

“…The effluent samples were harvested to determine NH 4 + -N, NO 2 − -N, and NO 3 − -N concentrations according to the standard methods. 19 The measurements of pH and DO were conducted with a portable dissolved oxygen meter (HQ40d, Hach, USA). Anammox sludge taken from the reactor was centrifugated and stored for the analysis of physicochemical parameters.…”

The effects of various dosages of graphene oxide (GO) on the performance of anammox and the underlying mechanisms are not yet fully understood, necessitating the provision of additional details. In this work, the dosage-dependent impacts of GO on the anammox system were investigated from the perspective of molecular biology analysis. The nitrogen removal efficiency (NRE) continuously increased at 10−100 mg/L GO, and a high nitrogen removal rate (NRR) was obtained at 25 mg/L GO. GO also improved the content of extracellular polymer substance (EPS) and the abundances of hzs and nirS genes. Molecular docking demonstrated that GO had a strong binding with the hydrazine synthase enzyme. Microbial analysis revealed that denitrifying bacteria, such as Denitratisoma and OLB13, were enriched, indicating that the high NRE could be attributed to the synergistic effect between denitrification and anammox processes. The analysis of microbial functions suggested that GO could impact various metabolic activities, such as quorum sensing, extracellular electron transfer, and membrane transport. Above all, this work provided detailed insights into the effects of different GO dosages on the anammox system.
