Greenhouse Gases Emissions of Constructed Wetlands: Mechanisms and Affecting Factors

Water, Journal Year: 2023, Volume and Issue: 15(16), P. 2871 - 2871

Published: Aug. 9, 2023

Constructed wetlands (CWs) widely applied for wastewater treatment release significant greenhouse gases (GHGs), contributing to global warming. It is essential characterize the comprehensive source-sink effects and affecting factors of GHGs in CWs, offering references guidance designing operating CWs better control GHG emissions. However, current reviews focus on individual emission mechanisms. With aid Web Science Core Collection database, relevant literature carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) emissions after 2010 was collected organized. As highlighted review, can produce transmit these into atmosphere, forming sources sequestration CO2 through plants photosynthesis, sinks GHGs. Their overall performance depends many factors. Hybrid Cyperus papyrus, alternifolius, Iris pseudacorus, adsorption substrates like Fe-C, low temperatures, a C/N ratio five are beneficial mitigation CWs. Future studies should in-depth research mechanisms benefits microorganisms relation This review provided understanding major bridging gap this field, helping researchers clarify context, providing valuable in-sights further scientific investigations.

Research Trends and Future Prospects of Constructed Wetland Treatment Technology in China

Water, Journal Year: 2024, Volume and Issue: 16(5), P. 738 - 738

Published: Feb. 29, 2024

With the intensification of water pollution problems worldwide, constructed wetlands, as a green, efficient, and energy-saving wastewater treatment technology, have gradually attracted wide attention scholars at home abroad. In order to better understand master research trends wetland technology in China promote its development, literature from 2000 2023 CNKI database Web Science (WoS) (located China) were selected objects. Then, CiteSpace software (6.2.R4) was used visualize analyze literature, revealing hot areas China. optimized way operation effect discussed provide theoretical technical basis for application our country. The results indicate that annual publication volume on wetlands is showing rapid upward trend. Among them, Chinese mainly focuses how improve nitrogen phosphorus removal rural domestic by matching different plants or developing combined processes. English remove emerging pollutants, such heavy metals resistance genes China, changing filling matrix microbial community structure new processes, related mechanisms been discussed. One spots future vigorously develop fuel cells, try overcome problem poor purification efficiency under complex conditions low temperature, carbon-nitrogen ratio, high load. strengthen application, specific optimization methods can be divided into two categories: self-optimization strategies increasing oxygen supply transfer, providing electron donor matrix, preventing blockage, combination processes coupled with anaerobic other technologies.
