张磊等：Climate technology transfer in BRI era: needs, priorities, and barriers from receivers’ perspective
ABSTRACT: Technology is an instrument to build BRI relationships, mitigate the environmental and climate impacts of BRI projects, as well as to enhance environmental sustainability in the regions. This study aims to reposition China in global climate technology transfer in BRI era and to obtain initial knowledge on needs, priorities, and barriers from the receivers’ perspective. Focus group method with aid of questionnaire survey and follow-up face-to-face interviews was adopted to capture th

穆云松等：Cysteine-enhanced reductive degradation of nitrobenzene using nano-sized zero-valent iron by accelerated electr...
ABSTRACT: As an aliphatic amino acid, cysteine (CYS) is diffuse in the living cells of plants and animals. However, little is known of its role in the reactivity of nano-sized zero-valent iron (NZVI) in the degradation of pollutants. This study shows that the introduction of CYS to the NZVI system can help improve the efficiency of reduction, with 30% more efficient degradation and a reaction rate constant nine times higher when nitrobenzene (NB) is used as probe compound. The rates of degrad

ABSTRACT: Activated sludge processes with an ultra-short sludge retention time (ultra-short-SRT) are considered to have potential for energy and resource recovery from wastewater. The present study focused on the sludge characteristics, system performance and microbial kinetics in ultra-short-SRT activated sludge (USSAS) processes using typical domestic wastewater (SRT = 0.5, 1, 2, 3 and 4 d). The results showed that compared with the sludge in conventional activated sludge (CAS) processes, t

ABSTRACT: Extracellular polymeric substance (EPS) is secreted by many organisms and makes up a significant constituent of natural organic matter in the environment. However, nothing is known about EPS's role in the reduction of pollutants by nano-sized zero-valent iron (NZVI). This research showed that the degradation kinetics of nitrobenzene (NB) by NZVI with EPS (0.0272 +/- 0.006 min(-1)) were 2.27 times lower than that without EPS (0.0618 +/- 0.006 min(-1)) in the first cycle, mainly due t

罗文斌、苏明明等： Influencing Mechanism of Tourist Social Responsibility Awareness on Environmentally Responsible Behavior.
ABSTRACT: Fostering tourist environmentally responsible behavior is critical for sustainable destination management, pertinent to both rural and urban settings. Tourist negative impact perception and social responsibility awareness are identified as important factors in shaping tourist environmental behavior. However, the influencing mechanism is not yet fully understood. Taking Yuelu Mountain, a key tourism attraction in Changsha City, Hunan Province of China, as an example, this study ex

王洪臣：城镇污水处理厂疫情防控应急对策
摘要：千家万户的污水,包括医院污水,都会直接或间接通过下水道进入城镇污水处理厂,因此,污水处理厂是全社会疫情防控的关键环节。城镇污水处理厂运行工作千头万绪,但在重大疫情面前,应着重处理好两件事情:一是在出现不利因素的情况下确保正常稳定运行;二是严格做好运行操作人员的安全防护。做好这两条就是最成功的应急处置。在整个疫情防控期间,全国5000多座城镇污水处理厂都能排除各种不利因素保持正常运行,让每天产生的两亿多吨污水都得到正常处理,几十万一线运营人员在岗位上不被病毒感染,这就是污水处理行业对全国疫情防控的最大贡献。

王洪臣：关于疫情防控期间医疗污水和城镇污水处理若干问题的建议
摘要： 新冠病毒感染的肺炎存在"粪口传播"可能,因此加强医院污水和城镇污水防控具有重要现实意义。在源头上强化医疗污水消毒处理,选择性优化消毒方式、药剂种类和投加量,确保病毒在源头上得到有效控制;城镇污水处理厂应确保稳定运行,在整体上提升运行保障等级,加大设施设备巡检和水质监测频次;对于城镇污水收集系统,应以防为主,避免扰动;同时,应严格做好不同污水处理系统中工作人员的安全防护。

王明玥等：Impact of scaling on aeration performance of fine-pore membrane diffusers based on a pilot-scale study
ABSTRACT: Aeration systems consume a large amount of energy in wastewater treatment plants. Fine-pore membrane diffusers are most commonly used in aeration systems. Scaling and fouling on these membrane diffusers will lead to decreased performance in aeration and increase energy consumption. This pilot-scale study focused on the scaling of the three kinds of fine-pore membrane diffusers under different influent hardness conditions. The results showed that the diffusers were mainly polluted by ca

ABSTRACT: Tourism can be an important strategy for conserving traditional agricultural systems and potentially enhancing livelihoods of hosting communities. The intricate and complex relations between agricultural heritage conservation, tourism and community livelihoods are examined at a GIAHS site in China. Through multistakeholder interviews, the study illustrates that the increased government support and public awareness after GIAHS designation do not ease the struggle between conservation
