Special Issue Information

Dear Colleagues,

Affected by water pollution, water shortage, and flood disaster, the water ecological environment is seriously damaged. Groundwater in the main river system, lakes, coastal waters, and other areas is polluted to varying degrees. In the river area, this manifests mainly via organic pollution; in lakes, via water eutrophication; and in the nearshore sea area, via inorganic nitrogen, active phosphate, heavy metals, etc. It is of great significance to study the key water ecological restoration technology and to improve water environment quality.

Water ecological restoration technology refers to the selection of various methods to repair the damaged aquatic ecosystem’s biological populations and ecological structure, strengthen the main functions of the aquatic ecosystem and rebuild a healthy ecological water body, including constructed wetland, stabilization ponds, ecological floating islands, ecological floating beds, etc.

This Special Issue welcomes high-quality articles in the field of water pollution treatment and water ecological restoration. Research areas may include (but are not limited to) the keywords listed below.

Discharging large amounts of domestic and industrial wastewater drastically increases the reactive nitrogen content in aquatic ecosystems, which causes severe ecological stress and biodiversity loss. This paper reviews three common types of denitrification processes, including physical, chemical, and biological processes, and mainly focuses on the membrane technology for nitrogen recovery. The applicable conditions and effects of various treatment methods, as well as the advantages, disadvantages, and influencing factors of membrane technologies, are summarized. Finally, it is proposed that developing effective combinations of different treatment methods and researching new processes with high efficiency, economy, and energy savings, such as microbial fuel cells and anaerobic osmotic membrane bioreactors, are the research and development directions of wastewater treatment processes.

A review of the characterization and functions of extracellular polymeric substances (EPS) of microbial aggregates in biological wastewater treatment systems is presented in this paper. EPS represent the complex high-molecular-weight mixture of polymers excreted by microorganisms generated from cell lysis as well as adsorbed inorganic and organic matter from wastewater. EPS exhibit a three-dimensional, gel-like, highly hydrated matrix that facilitates microbial attachment, embedding, and immobilization. EPS play multiple roles in containments removal, and the main components of EPS crucially influence the properties of microbial aggregates, such as adsorption ability, stability, and formation capacity. Moreover, EPS are important to sludge bioflocculation, settleability, and dewatering properties and could be used as carbon and energy sources in wastewater treatment. However, due to the complex structure of EPS, related knowledge is incomplete, and further research is necessary to understand fully the precise roles in biological treatment processes. Full article
