Special Issue Information

Dear Colleagues,

The biochemical wastewater treatment process has huge advantages, such as high efficiency, less energy consumption, simple operation and less investment, which can meet the requirements of modern urban sewage treatment. The biological wastewater treatment process is mainly a method involving the use of microbial metabolism to remove organic and nutrient pollutants in wastewater under aerobic or anaerobic conditions. For now, many novel processes focusing on anaerobic ammonia oxidation (anammox), complete ammonia oxidation (comammox), partial nitrification, partial denitrification, enhanced biological phosphorus removal (EBPR), denitrifying phosphorus removal (DPR), endogenous denitrification, denitrifying anaerobic methane oxidation (DAMO), etc., have attracted much more attention.  However, regarding the use of biological wastewater treatment processes, there is still a great need to continue to strengthen the research and innovation of the processes to further improve the carbon and nutrient removal efficiencies, and thus to contribute to the sustainable development of urban water resources. Moreover, many components can be recovered during the treatment process and from residuals from wastewater treatment, such as carbons, nutrients, metals and biodegradable plastic. New trends and technological innovations still need to be developed for the full-scale implementation and use of biological wastewater treatment.

In order to trace the research progress of biological wastewater treatment processes and nutrient recovery technologies, a Special Issue will be organized by Water. This Special Issue focuses on original articles or review articles related to biological wastewater treatment processes and nutrient recovery, including but not limited to the following:

  • Energy saving wastewater autotrophic/heterotrophic nitrogen removal processes, such as anammox, comammox, partial denitrification and nitritation;
  • Enhanced phosphorus removal from wastewater;
  • Development and utilization of carbon sources in sewage/sludge, such as anaerobic fermentation, VFAs and methane utilization;
  • Greenhouse gas emissions;
  • Biological treatment of emerging pollutants;
  • Biological processes involved in the removal of toxic pollutants;
  • Biochemical treatment technology of odorous gas during wastewater treatment processes;
  • Carbon, nitrogen and phosphorus recovery and reuse technologies;
  • Other related topics

When treating municipal wastewater, nitrogen removal is often limited due to low C/N, which needs to be compensated for by additional carbon source injections. This study investigated the feasibility of using industrial-waste polyglycolic acid (PGA) as a carbon source for denitrification in an SBR to obtain an economical carbon source. The results revealed that an optimal denitrification performance in a methanol-fed activated sludge system was achieved with a PGA dosage of 1.2 mL/L, a pH of 7–8, and a dissolved-oxygen (DO) concentration of 3 ± 0.5 mg/L. Under these conditions, all quality parameters for effluent water met the required criteria [COD < 50 mg/L; TN < 15 mg/L; NH4+-N < 5(8) mg/L]. PGA enhanced the variety and richness of microbial communities, thereby markedly increasing the relative abundance of major phyla such as Proteobacteria and Bacteroidota and major genera such as Paracoccus and Dechloromonas. Furthermore, PGA upregulated the expression of nitrogen-metabolism-related genera, including amo, hao, nar, and nor, which improved the denitrification performance of the system. This study provides a reference for applying PGA as a carbon source for low-C/N-wastewater treatment and solid-waste utilization. Full article
