However, the mechanism underlying microbial N removal and the characteristics of N-cycle in riparian soils remain elusive.

    Abstract Dibutyl phthalate (DBP) is a typical contaminant in pharmaceutical wastewater with strong bio-depressive properties which potentially affects the operation of municipal wastewater treatment systems. Based on a year-round monitoring of the quality of influent and effluent of a full-scale pharmaceutical wastewater treatment plant in Northeast China, the DBP was found to be the representative pollutant and its concentration in the effluent ranged 4.28 ± 0.93 mg/L. In this study, the negative effects of DBP on a pilot-scale A²/O-MBR system was investigated. When the influent DBP concentration reached 8.0 mg/L, the removals of chemical oxygen demand (COD) and total nitrogen (TN) were significantly inhabited (P < 0.01), with the effluent concentration of 54.7 ± 2.6 mg/L and 22.8 ± 3.7 mg/L, respectively. The analysis of pollutant removal characteristics of each process unit showed that DBP had the most significant effects on the removals of COD and TN in the anoxic tank. The α- and β-diversity in the system decreased significantly when the influent DBP concentration reached 8.0 mg/L. The impacts of DBP on known nitrifying bacteria, such as Nitrospira, and phosphorus accumulating organisms (PAOs), such as Cadidatus Accumulibacter, were not remarkable. Whereas, DBP negatively affected the proliferation of key denitrifying bacteria, represented by Simplicispira, Dechloromonas and Acinetobacter. This study systematically revealed the impacts of DBP on the pollutants removal performance and the bacterial community structure of the biological municipal wastewater treatment process, which would provide insights for understanding the potential impacts of residues in treated pharmaceutical wastewater on biological municipal wastewater treatment.

    Abstract Dissolved organic matter (DOM) is an important constituent of wastewater treatment plant (WWTP) effluent. A novel combined tidal and subsurface flow constructed wetland (TF-SSF-CW) of 90 L was constructed for a ten-month trial of advanced treatment of the WWTP effluent. Excitation emission matrix (EEM) fluorescence spectroscopy, parallel factor (PARAFAC) analysis and a two end-member mixing model were employed to characterize the composition and removal process of the effluent DOM (EfOM) from the WWTP. The results showed that the TF-SSF-CW performed an efficient EfOM removal with dissolved organic carbon (DOC) removal rate of 88% and dissolved organic nitrogen (DON) removal rate of 91%. Further analysis demonstrated that the EfOM consisted mainly of two protein moieties and two humic-like groups; protein moieties (76%) constituted the main content of EfOM in raw water and humic-like groups (57%) became the dominating contributor after treatment. The EfOM from the WWTP was mainly of aquatic bacterial origin and evolved to a higher proportion of terrigenous origin with higher humification in the TF-SSF-CW effluent. A common controlling treatment-related factor for determining the concentrations of the same kind of substances (protein groups or humic-like groups) was revealed to exist, and the ratio of removal rates between the same substances in treatment was calculated. Our study demonstrates that the TF-SSF-CW can be a novel and effective treatment method for the EfOM from WWTPs, and is helpful for understanding of the character of EfOM in wetland treatment.

    Abstract Nitrogen cycling in riparian zones is a complex process. Few studies have comprehensively explored the physico-chemical and biological removal of nitrogen in riparian zones. By summarizing 123 studies published between 1980 and 2020, we systematically review nitrogen removal from surface runoff, groundwater, plant uptake and microbial degradation in soil, in an attempt to comprehensively outline the nitrogen removal process in riparian zones. The results indicate that nitrogen reduction with buffer widths showed a one-phase exponential decay trend in both surface runoff (R² = 0.36) and underground water (R² = 0.16). At a width of 10–15 m, the average nitrogen reduction in surface runoff and underground water reached approximately 79 and 59%, respectively. In the investigation of microbial and plant nitrogen removal, denitrification rates and nitrous oxide (N₂O) emissions rates increased by 25 and 94%, respectively, in 2010–2020 compared with 2000–2010. The nitrogen uptake, denitrification, and N₂O emissions efficiency of forests were notably higher than those of grass. Warm weather is beneficial to denitrification and N₂O emissions; however, nitrogen uptake by plants showed a downward trend over the past 20 years. Environmental factors (e.g., climate, vegetation, water quality and hydrology, topography, and soil) showed notable and sensitive impacts on nitrogen retention and the microbial nitrogen cycle. In addition, legacy nitrogen had a long-term effect on waterbodies and may require an extended period to deplete and recover. This meta-analysis provides a comprehensive and scientific basis for understanding retention effects of nitrogen in riparian zones of agricultural areas.
