“…AF stands usually grow close to universities, schools, institutes and government agencies, where intensive management is carried out in terms of watering, fertilizing, and tending. Similar activities, along with rational pruning and the choice of diverse species for afforestation purposes, should be extended also to other urban forest types in other locations to maximize their ecological benefits (Qin et al 2006).…”

“…So far, studies on environmental benefits of urban forests have mostly focused on reducing urban heat island effect (Bao et al 2001, Qin et al 2006, comparing the cooling effect of different tree species and community types (Wu et al 2008, Bowler et al 2010, Liao et al 2012, exploring their relations with biodiversity and trees growth (Marziliano et al 2013, Pesola et al 2017 or investigating the physiological mechanisms like photosynthesis and leaf transpired water loss (Zheng et al 2008, Xu et al 2015, in order to provide suggestions for urban forest management. Remote sensing technology and the corresponding model inversion methods have also been used to assess the environmental benefits of urban green space (Liu & Guo 2009, Imhoff et al 2010, Gao et al 2014, Mariani et al 2016.…”

Microclimate regulating functions of urban trees and their associations with environmental factors and tree-growth characteristics are important for management and ecological evaluations. In this study, a total of 637 trees distributed in the Changchun urban region (ca. 400 km 2 , northeastern China) were sampled in four different types of urban forests (AF: affiliated forests; RF: roadside forests; LF: landscape and relaxation forests; EF: ecological welfare forests). Tree growth-related parameters and environmental factors (inside and outside the forest) were simultaneously measured, and location-dependent differences in shading, cooling and humidifying effects were assessed, along with their associations with the measured variables. We found that urban forests in Changchun reduced the incident sunlight by 74-86% and increased air relative humidity by 3-7%, on average. Air, soil, and upper-canopy temperatures were decreased approximately by 3 °C, <1 °C and 1 °C, respectively, showing a 3-dimensional cooling effect of urban forests on both air and soil. Shading, cooling and humidifying effects significantly differed among the four forest types, with AF stands showing the highest comprehensive scores for all the microclimate regulation functions. Regression analyses and redundancy analysis revealed that urban forests had much stronger effect in terms of microclimate regulation at sunny days with high temperature, and low air humidity. In general, stands with larger trees showed the higher regulating functions, regardless of the stand structure and composition. The results of this study may help urban forest management and planning aimed at maximizing their ecological services.

“…In-situ remediation is a technique for effectively purifying polluted surface waters. In fact, many in-situ remediation techniques such as ecological floating beds and artificial wetlands have been widely used for remedying polluted surface waters and achieved satisfactory outcomes; the plant products processed may be further employed as food of animals and even human beings or processed into biogas, bio-fertilizer, and biomaterials [2,3]. However, these technologies have a range of unexpected deficiencies arising from low temperature, limited intake of plants, limited biomass concentration and low water transparency [4].…”

Two kinds of fillers were chosen to explore surface water remediation with a sequencing batch biofilm reactor (SBBR). By comparing SBBR with the plastic filling reactor (PFR), which was considered as the control group, the effectiveness of a filamentous bamboo reactor (FBR) for removing organic substances, nitrogen and phosphorous as well as biomass changes. Experimental results suggested that in using a FBR the average removal rates of COD Mn Рассмотрены два типа наполнителей для исследования рекультивации поверхностных вод с помощью последовательного биопленочного реактора (SBBR).

Показано, що FBR недостатньо ефективний для видалення ТР. Використання бамбукових ниток в якості носіїв і джерела вуглецю, їх високий вміст гідрофільних функціональних груп і рясна мікробна фація сприяли ефективному відновленню води.

Adopting a greywater treatment system that provides economical, effective, and sustainable treated greywater over a longer span helps to address water scarcity. The present study focuses on treating greywater generated from hostels using a floating plant treatment system (FPTS) planted with water hyacinth. The additional units, a sand filter and an activated charcoal filter, were attached in series to FPTS to improve the treated greywater quality. The treatment system was operated for 90 days with daily monitoring of influent and effluent parameters. The treatment performance was evaluated based on the removal efficiency for total suspended solids (TSS), turbidity, chemical oxygen demand (COD), ammonia, sulphate, phosphate, and faecal coliform (FC) of 74.81% ± 5.74%, 99.76% ± 0.05%, 95.70% ± 4.10%, 99.16% ± 2.08%, 48.22% ± 1.80%, and 100%, 97.27% ± 1.48%, respectively. The study showed that the system effectively treats greywater, making it suitable for non‐potable purposes on educational institution's campuses.
