“…COD was observably associated with black-odor-related microorganisms. Since COD is an index reflecting organic matter when the inorganic reductant is limited, organic matter is the primary contributor to the black-odor water [5,57]. The excess organic matter would cause microbes to utilize the dissolved oxygen in water rapidly, thereby leading the waterbodies to remain anaerobic.…”

“…Physiochemical factors, such as TP, Fe 2+ , and S 2− were significantly correlated with black-odor-forming microbes. Previous studies have reported that phosphorus could alter the occurrence of black-odor water by reducing the activity of organic matter decomposers [57]. The activity of Fe 2+ is higher than that of Mn 2+ , Cu 2+ , and other metal ions; hence, Fe 2+ promptly combines with S 2− to precipitate iron sulfide (FeS), which has been proven to be the predominant contributor to black water.…”

The black-odor phenomenon has been widely reported worldwide and recognized as a global ecological risk for aquatic environments. However, driving factors for black-odor-related microorganisms and potential self-remediation strategies are still poorly understood. This study collected eight water samples (sites A–H) disturbed by different factors from the Jishan River located in Jinmen, Hubei Province, China. Black-odor-related environmental factors and functional bacterial structure were further measured based on the basic physicochemical parameters. The results indicated that different types of disturbed conditions shape the distribution of water quality and microbial community structures. Site B, which was disturbed by dams, had the worst water quality, the lowest abundance of functional microbes for Mn, Fe, and S biotransformation, and the highest abundance of functional microbes for fermentation. The natural wetlands surrounding the terminus of the river (site H) were keys to eliminating the black-odor phenomenon. Potential black-odor-forming microorganisms include Lactococcus, Veillonella, Clostridium sensu stricto, Trichococcus, Rhodoferax, Sulfurospirillum, Desulfobulbus, and Anaeromusa-Anaeroarcus. Potential black-odor-repairing microbes include Acinetobacter, Mycobacterium, and Acidovorax. pH and COD were paramount physiochemical factors contributing to blackening-odor-related microorganisms. This study deepens our understanding of driving factors for black-odor-related microorganisms and provides a theoretical basis for eradicating the black-odor phenomenon.

“…P-rich excreta could be leached into groundwater that can increase the growth of algae and aquatic plants leading to water eutrophication ( Ryden et al, 1974 ; Keshavarz, 2003 ; Knowlton et al, 2004 ; Ayoade et al, 2022 ). It is also known that environmental P stimulates organic matter degradation ( Li et al, 2021 ) encouraging the production of odorous compound through microbial activity. In addition, dietary P is considered a nutritional factor affecting gut microbiota ( Witzig et al, 2015 ; Ye et al, 2021 ) which could lead to odor production.…”

“…There are a large number of nutrients such as nitrogen (N) and phosphorus (P) from municipal garbage, waste water and atmospheric deposition in rainwater runoff, which aggravate the surface rainwater runoff pollution (Djukic et al, 2016;Chen et al, 2022). When these N and P pollutants entered the natural water body with rainwater runoff, they can cause eutrophication of water body (Kabenge et al, 2016;L. Li et al, 2021a;Wu et al, 2020).…”

Bioretention cells are an important facility to solve the hydrological and non-point pollution problems in urban areas, especially phosphorus. In this paper, ceramsite composite was made from coal ash and modified by nano-iron through coprecipitation and reduction, which was used to remove the phosphorus in the water. The results of the characteristics of the ceramsite composite using scanning electron microscope showed that the surface of the ceramsite loaded with nano-iron became rougher and the iron nanoparticles were uniformly distributed on the surface, and there was no obvious agglomeration of nano-iron particles. The loading effect was good and the activity of the ceramsite was greatly improved. The results from the static and dynamic continuous experiments indicated that the modified ceramsite with nano-iron had a good removal effect on phosphorus, and the removal rate reached over 99%. The results of this study can provide a new way for the resource utilization of coal ash, and also inspires a new idea for the improvement of filler in bioretention facilities.
