“…Since 1950s, Germany has been the first country to evaluate the pollutant removal capabilities of the urban constructed WQT wetland treatment system. When the pollutant concentration or load is within the wetland purification threshold range of 80% -99%, the pollutant removal capabilities of the urban constructed WQT wetland is better than other solutions [3] .…”

Shortage of water resources has become one of vital problems world widely, so improvement for making more sufficient use of urban tailwater is one of significant issues for environmental engineering as well as landscaping. With different technologies and various of its types, constructed wetlands can be applied to purify lightly polluted water. Urban water quality treatment (WQT) wetland is an economical and efficient infrastructure for tertiary wastewater treatment, which would be potential once its purification capabilities could be developed. Three principles, including ecological, service, and aesthetic principles, have been concluded in this research. In addition, relationships among practical landscape design strategies of constructed WQT wetlands and other factors, including its water treatment performance, simulation analysis and landscape aesthetics, should be applied in practical landscape design, which will enable them to play a key role as one of nature-based solutions (NBS) in future.

Water environments of urban constructed water quality treatment (WQT) wetland waterscapes are strongly related to water quality, whereas scenic beauty values help achieve better aquatic environments. However, correlations between several water quality indicators (WQIs) and scenic beauty indexes (SBIs) have not been thoroughly revealed in the existing studies. In this research, an analytic hierarchy process (AHP)-based on scenic beauty estimation (SBE) per site in two WQT wetlands has been developed. The weights of indicators were determined by the AHP voting, which includes three main criteria, i.e., conditions of vegetation, physical geographical conditions, and human geographical conditions. SBIs are voted and calculated from the professional group and the unprofessional group. WQIs of typical pollutants (i.e., dissolved oxygen (DO), CODCr, NH3-N, pH, and total phosphorus) were sampled in situ simultaneously. Inter-relationships among SBIs and WQIs are indicated by correlative analysis and a regression model, which highlights that DO increase, CODCr removal, and NH3-N removal can explain 68.8% of changes in the SBI. Accordingly, applications for WQT wetland eco-engineered landscaping (EEL) were suggested to be conducted on quantitative estimations in three aspects, i.e., following strategies of EEL, improving WQT techniques, and applying the attention restoration theory. With deeper comprehension of SBIs, practical design, management, and maintenance of WQT wetlands will be optimised.

Urban constructed water quality treatment (WQT) wetlands are often applied to be integrated with ecological engineered landscaping (EEL) measures for wastewater treatments. This study aims to identify the interrelationships between the hydrological factors and pollutant removal contributions of typical WQT wetlands at each WQT stage, i.e., subsurface flow wetlands (SSF), vertical flow wetlands (VF), free surface flow wetland (FSF), floating wetland island (FWI), aeration ponds (APs), and ornamental ponds (OPs) in four typical wetland parks in Hangzhou, China. Water quality indices (WQIs) of wetland parks have been monitored. Interactive comparisons and correlations between hydrological indicators and WQIs (i.e., pH, DO, NH3-N, CODCr, and TP) are developed, while the removal contribution of each WQI was explained. It is found that each stage had heterogeneous effects on wastewater treatment due to various geo-ecological factors, including hydraulic conditions, plant type, and microbial microenvironment, whereas the temperature of waterbodies affected WQT performances at full sites in all seasons. Three corresponding EEL guiding principles were derived, i.e., optimising the EEL measures, adapting planting methods, and incorporating multifunctional design and adaptive management. The findings will be helpful for improving the efficacy of WQT stages as one of the potential ecosystem services provided by wetland parks.
