“…The new CW type, IVF-CW, reserves more than half its area for mesic habitat, favoring the growth of mesophytic species (eg Lolium perenne, Coix lacryma-jobi, and Arundo donax). The number of plant species growing in IVF-CW is higher than in other types Yang et al 2005), since mesophyte species are far more numerous than hydrophyte species.…”

“…Macrophytes frequently used in CW systems include emergent plants (eg Phragmites australis, Typha latifolia, and Canna indica), submerged plants (eg Ceratophyllum demersum), floating leaved plants (eg Nymphaea tetragona and Nymphoides peltata), and free‐floating plants (eg Eichhornia crassipes and Lemna minor). Although more than 80 plant species have been utilized in CW systems globally, according to the literature (Yang et al . 2005), only half of the CW systems in China employ one or two of these species (WebFigure 1).…”

Constructed wetlands (CWs) are an emerging, environmentally friendly engineering system employed in China. They require lower investment and operation costs while providing higher treatment efficiency and more ecosystem services than conventional wastewater treatment methods. Introduced to China in 1987, CW systems used for wastewater treatment have rapidly increased in number, particularly since the late 1990s. This review summarizes the state‐of‐the‐art application of CW systems for water pollution treatment by reviewing the basics of the technology and its historical development and performance efficiency. Current progress, limitations, future concerns, and the challenges of CW technologies are also discussed. Also highlighted is the need for sufficient and appropriate data to assist in the further development of CW systems and the implementation of integrated “bottom‐up” and “top‐down” approaches by both the public in general and government bodies in particular.

“…During the postfermentation of pu-erh tea, the main flavan-3-ols are gradually degraded, and the content of gallic acid is increased (Gong et al, 1992;Zhe, Zhang, Chen, Zhang, & Yang, 2005). The theanine content is also decreased and even undetectable in pu-erh tea, but the caffeine and theobromine are stable through the manufacture process of dark teas (Qin, Li, Tu, Ma, & Zhang, 2012.…”

Tea is a typical processed beverage from the fresh leaves of Camellia sinensis [Camellia sinensis (L.) O. Kuntze] or Camellia assamica [Camellia sinensis var. assamica (Mast.) Kitamura] through different manufacturing techniques. The secondary metabolites of fresh tea leaves are mainly flavan‐3‐ols, phenolic acids, purine alkaloids, condensed tannins, hydrolysable tannins, saponins, flavonols, and their glycoside forms. During the processing, tea leaves go through several steps, such as withering, rolling, fermentation, postfermentation, and roasting (drying) to produce different types of tea. After processing, theaflavins, thearubigins, and flavan‐3‐ols derivatives emerge as the newly formed compounds with a corresponding decrease in concentrations of catechins. Each type of tea has its own critical process and presents unique chemical composition and flavor. The components among different teas also cause significant changes in their biological activities both in vitro and in vivo. In the present review, the progress of tea chemistry and the effects of individual unit operation on components were comprehensively described. The health benefits of tea were also reviewed based on the human epidemiological and clinical studies. Although there have been multiple studies about the tea chemistry and biological activities, most of existing results are related to tea polyphenols, especially (‐)‐epigallocatechin gallate. Other compounds, including the novel compounds, as well as isomers of amino acids and catechins, have not been explored in depth.

Rhizosphere microorganism is an important bio-component for wastewater treatment in constructed wetlands (CWs). Microbial abundance and enzyme activities in the rhizospheres of nine plant species were investigated in an integrated vertical-flow CW. The abundance of denitrifiers, as well as urease, acid, and alkaline phosphatase activities were positively correlated to plant root biomass. The abundance of bacteria, fungi, actinomycetes, ammonifiers, denitrifiers, and phosphorus decomposers, related to nutrient removal efficiencies in CWs, greatly varied among rhizospheres of different plant species (p < 0.05). Significant differences in rhizosphere enzyme activity among plant species were also observed (p < 0.05), with the exception of catalase activity. The principal component analysis using the data of microbial abundance and enzyme activity showed that Miscanthus floridulus, Acorus calamus, and Reineckia carnea were candidates to be used in CWs to effectively remove nitrogen and phosphorus from wastewater.
