Summary: Steel slag substrate constructed wetlands (SSCWs) can effectively remove phosphorus from sewage through Ca-P precipitation and adsorption. Combining steel slag with other substrate materials in SSCWs significantly increased the removal of total nitrogen and ammonium nitrogen, but reduced the removal of total phosphorus. Plant cultivation can compensate for the decline in phosphorus removal and improve the simultaneous removal of nitrogen and phosphorus. Horizontal flow SSCWs achieve higher phosphorus removal capacity compared to vertical flow SSCWs. Operational parameters significantly affect the nitrogen and phosphorus removal capacity of SSCWs.

Summary: This study proposes a novel constructed wetland by coupling with pyrite and steel slag. The results showed that steel slag addition increased total nitrogen removal by 40% to 54%, and the higher removal of total phosphorus was mainly attributed to substrate adsorption and metal ions precipitation. The findings of this study provide new insights into the molecular mechanism of carbon, nitrogen, and sulfur metabolism in the pyrite-steel slag based constructed wetland.

Summary: This study aimed to improve the ammonia removal performance of tidal flow constructed wetlands under high hydraulic loading rates by adding steel slag. The results demonstrated that steel slag could enhance NH4+-N removal efficiency by regulating pH and stimulate the growth of ammonia-oxidizing microorganisms, leading to better ammonia removal performance. However, the effect on total nitrogen and phosphorus removal was limited.

Summary: Steel slag has been proven to effectively remove phosphorus and mitigate pollution in freshwater systems. However, the oversimplification of steel slag behavior as a phosphorus sorption material calls for individual characterization of slag samples to determine their phosphorus removal capacity. Coating steel slags with aluminum significantly improved phosphorus removal performance, especially under rapid flows.

Summary: The novel simultaneous nitrogen and phosphorus removal process combines nitrification, endogenous denitrification, and denitrifying phosphorus removal to achieve high-efficiency nutrient removal in constructed wetlands. The success of the process is attributed to the utilization of DGAOs and DPAOs in utilizing carbon sources for endogenous denitrification and denitrifying phosphorus removal.

Summary: The study found that using intertidal wetland sediments as a microbial source for CWs can effectively improve phosphorus removal rates, with bacteria such as phosphorus-accumulating organisms enhancing microbial transformation of phosphorus. However, the addition of IWS increased phosphorus loss via substrate accumulation and decreased phosphorus removal rate via plant uptake.

Summary: Constructed wetlands are recognized as effective measures for reducing pollution and improving water quality. The efficiency of wetlands varies based on various factors, such as system type, design, residence time, and loading rates. Monitoring and assessing their effectiveness is crucial in light of climate change and land management intensification.

Summary: Iron oxides can nourish iron reducing bacteria and increase available electrons in constructed wetland systems. The addition of limonite improved nitrogen removal efficiency but excessive addition may induce phosphorus release. The study highlights the importance of balancing iron cycling for improved nutrient removal in wetlands.

Summary: This study demonstrated the feasibility of achieving phosphorus removal through enhanced biological phosphorus removal (EBPR) in an intermittent aeration constructed wetland (CW). The integration of EBPR with simultaneous nitrification-endogenous denitrification (SNED) significantly improved phosphorus and nitrogen removal efficiency, providing a novel approach for advanced nutrient removal in CWs.

Summary: This study investigated the sorption characteristics of natural manganese ore (NM) and its removal efficiency of ammonium and phosphorus from WWTP effluent in a simulated vertical flow NM constructed wetland (NM-VFCW). The results showed that NM could effectively sorb ammonium and phosphorus with a high removal efficiency, particularly for phosphorus. The manganese ore sand is highlighted as a powerful substrate for simultaneous advanced removal of phosphorus and ammonium in constructed wetland systems.

Summary: This study aims to enhance the phosphorus adsorption capacity of constructed wetlands by using thermally modified sepiolites. The results showed that the specific surface area and adsorption capacity of thermally modified sepiolite were higher than those of natural sepiolite. The constructed wetlands based on thermally modified sepiolite achieved a high phosphorus removal efficiency.

Summary: An efficient and simple passive treatment system for manganese removal was developed and verified for its tolerance to iron. The steel slag mixed with limestone showed the highest removal efficiency and tolerance to iron. The precipitation of manganese as carbonates near the surface of limestone was found to be the major mechanism for iron tolerance.
