Special Issue Information

Dear Colleagues,

The application of constructed wetlands (CWs) has increased quickly in water treatment and reuse in recent years. CWs have been used in wastewater, natural water, flood water, fishing water, agriculture pollution water treatment, and so on. Pollutants, especially the remaining nutrients after preliminary treatment, including new pollutants such as heavy metals, are still the focus of CW applications in water treatment. This Special Issue focuses on new water treatment techologies, pollutants removal characteristics, biomass and energy recycle, and water reuse evaluation with CWs.

In this Special Issue, original research articles and reviews are welcome. The topics of this Special Issue include, but are not limited to: (1) recent CW application projects and studies in water and wastewater treatment; (2) innovative technologies and practices related to CWs in water treatment; (3) the safety and risk evaluation of water treatment with CWs; (4) biomass and energy recycle in CWs; (5) nutrients and new pollutants’ removal and transfer in CWs; (6) developing new CWs based on carbon neutrality; and (7) other technologies and strategies for the optimization of CWs in water treatment and reuse.

We look forward to receiving your contributions.

Insufficient denitrification and limited phosphorus uptake hinder nitrogen and phosphorus removal in constructed wetlands (CWs). Sponge iron is a promising material for the removal of phosphorus and nitrogen because of its strong reducing power, high electronegativity, and inexpensive cost. The influence of factors including initial solution pH, dosage, and the Fe/C ratio was investigated. A vertical flow CW with sponge iron (CW-I) was established, and a traditional gravel bed (CW-G) was used as a control group. The kinetic analysis demonstrated that for both nitrogen and phosphorus, pseudo-second-order kinetics were superior. The theoretical adsorption capacities of sponge iron for nitrate (NO3−-N) and phosphate (PO43−-P) were 1294.5 mg/kg and 583.6 mg/kg, respectively. Under different hydraulic retention times (HRT), CW-I had better total nitrogen (TN) and total phosphorus (TP) removal efficiencies (6.08–15.18% and 5.00–20.67%, respectively) than CW-G. The enhancing effect of sponge iron on nitrogen and phosphorus removal was best when HRT was 48 h. The increase in HRT improved not only the nitrogen and phosphorus removal effects of CWs but also the reduction capacity of iron and the phosphorus removal effect. The main mechanisms of synergistic nitrogen and phosphorus removal were chemical reduction, ion exchange, electrostatic adsorption, and precipitation formation. Full article

The tail wastewater from sewage treatment facilities usually lacks carbon sources, and its subsequent treatment for deep nitrogen removal is difficult in natural conditions. In this study, the constructed wetland (CW) was integrated with microbial fuel cell (MFC) with high-density polyethylene (HDPE) fillers as the main matrix to improve nitrogen removal under inefficient carbon source conditions. Compared with the regular MFC and CW systems, MFC-CW attained higher nitrogen removal under low-carbon source conditions. The influence of influent carbon/nitrogen ratio (C/N) on the denitrification and electricity-generation performance was explored. Although the increase of carbon source simultaneously improved chemical oxygen demand (COD), ammonia (NH4+-N), nitrate (NO3−-N) and TN removal, the power generation during the carbon source adjustment showed low relation with the variation of influent COD in the range of 40–120 mg/L. CW was more dependent on carbon sources, and the addition of bioelectrochemical systems into MFC-CW could reduce the dependence of nitrogen removal on carbon sources, especially under low carbon source conditions. These findings offer valuable insights into the potential applications of MFC-CW for tail water treatment, and its parameters for utilization in real CWs should be explored in future studies.
