摘要 :
As anthropogenic antibiotics, quinolones, e.g., ofloxacin have adverse impacts on ecological systems and human heaths. The removal of quinolones is of great importance, and adsorption techniques have been widely used to remove this hazardous contaminant. However, a robust and easy-operating adsorbent is still emergently required due to the complex chemical structure of quinolones. In this study, we successfully synthesized the promising metallic carbons (MCs) containing carbon nanotubes and cobalt nanoparticles by carbonizing Zn/Co-ZIF at 900 degrees C. Three different molar ratios of Co and Zn were applied to optimize the adsorption capacity on ofloxacin (OFL). Results showed MC with molar ratio of Co and Zn at 3:1 (Co-CNT/NPC3/1) achieved the maximal adsorption capacity to 118.3 mg g-1. Its adsorption performance was satisfied in the pH range from 5 to 9 and ionic strengths at 0.01 M. The main mechanisms for these adsorptions were identified as electrostatic attraction, metal coordination and pi-pi EDA. Removal efficiencies of quinolones higher than 68 mg g-1 indicated the strong feasibility of this adsorbent for wastewater treatments. The regeneration of Co-CNT/NPC3/1 at 600 degrees C allowed its at least 4-time reusability and its magnetic property enabled external magnets to recycle it from real environments.

摘要 :
减少粮食浪费不仅关乎粮食安全,而且对于温室气体减排与生态环境保护也至关重要。本文基于生命周期理论,构建了餐厅食物消费模型;然后通过对北京某风味餐厅的现场调研,量化评估了餐厅每人次产生的平均温室气体排放量,并对餐厅剩余食物产生的原因以及通过减少餐厅食物剩余带来的温室气体减排潜力进行了系统分析。研究结果表明,一个中等规模的北京风味餐厅的总温室气体排放量可达每年225.28 t CO_2当量(CO_2e),即2.50kgCO_2e/人次;人均每餐食物剩余为97.2 g。朋友聚餐以及其他公共环境中消费的食物剩余量均明显高于普通日常就餐,点菜过多和口味与想象不符是产生剩余的重要原因;而学历、年龄较低的消...

摘要 :
为快速掌握区域内全部水泥企业的碳排放情况,在部分企业实际生产数据未知时,也能建立其生产碳排放清单,文中基于熟料生产特征,构建了可根据设备设计产能和运行时长两种参数来核算企业CO_2排放的数值模型。以京津冀地区59条典型水泥熟料生产线的生产数据作为统计样本,借助Eviews对生产线的实际产能、熟料烧成煤耗与设计产能间的关系进行回归分析,并引入了生产时间修正系数,完成了CO_2核算模型的建立。将其应用到京津冀地区全部106条水泥熟料生产线中,得出2018年度京津冀地区水泥熟料总产量,该核算值与数字水泥网发布的统计数据之间的相对误差均值为7.81%。通过核算,CO_2直接排放系数为0.93 t CO...

摘要 :
欧盟在2019年提出2050年碳中和目标,这一目标不只是一个长期目标,很多行业已经开始制定短期的具体行动方案和对策,并启动了实际行动。2020年9月中国在联大会议上宣布,力争在2060年前实现碳中和。碳中和目标会明显影响未来一些产业的生产工艺。对于工业中难以减排的行业,如钢铁、水泥、合成氨、乙烯、苯、甲醇等,为实现深度减排,氢基产业将是一个重要选项。绿氢的供应将会明显影响这些产业采用氢工艺的成本,进而影响产业的区域布局。通过本研究可以看出,未来中国主要基础产业的布局将出现明显变化,在考虑多种实现产业深度减排技术选择(如碳捕集与封存)的情况下,不少产业都将转向可再生能源富集和低成本地区,特别是光...

摘要 :
Globally 2 degrees C and 1.5 degrees C warming targets by 2100 was set up by Paris agreement, and academically supported by recently published IPCC reports. However, feasibility to realize the emission pathways to reach the targets were still under demanding from policy makers. In order to analyze the feasibility to follow the emission pathway to reach 2 degrees C and 1.5 degrees C targets, Integrated Policy Assessment Model of China (IPAC) modelling team has worked on the global emission pathway and emission scenario for China. This paper presents the scenario analysis by IPAC modelling team with focusing on energy and CO2 emission scenario from transport sector in China, under the national emission pathways to support global 2 degrees C and 1.5 degrees C targets. Technologies and measures for deep cut of CO2 emission in transport sector were presented. The finding says energy and CO2 emission scenario in transport could support national 2 degrees C scenario, which requiring CO2 emission peak before 2030, with technology progress in transport and strong policies on public transport and non-mobility transport. However in the 1.5 degrees C scenario, CO2 emission from transport need to be near zero by 2050. To be such kind of deep cut of CO2 emission by 2050, electric car and other electric vehicles have to play crucial role. There is large potential for electric car in next decades in China with technology progress by following the roadmap presented in this paper.

摘要 :
Ammonia (NH3) is an important precursor of PM2.5 (particulate matter with aerodynamic diameter below 2.5 mu m). In recent years, ammonia emissions from road traffic notably increased, growing pollution of PM2.5. Therefore, addressing spatial and temporal ammonia emissions from road traffic is a keyword for controlling urban traffic pollution. However, most of current China's ammonia emissions inventories are annual emissions, lack of spatial and temporal information, which is a gap for governments to make effective and practical policies in terms of controlling road traffic pollution. In this study, based on the built MOVES-Beijing Model, the ammonia emission factors of eight types of vehicle in Beijing, including passenger car (PC), TAXI, middle-duty vehicle (MDV), heavy-duty vehicle (HDV), light-duty truck (LDT), middle-duty gasoline truck (MDGT); middleduty diesel truck (MDDT) and heavy-duty truck (HDT), were obtained. And through the modified local speedflow model, the traffic flow was obtained acquisitively with the average speed data of the main roads in Beijing. The road length data were obtained according to the ranging function in the Gaode map and the status of Beijing. Then the high spatial and temporal ammonia emission inventory in Beijing was achieved. The results showed the order of ammonia emission factors (EFs) for different types of vehicles was MDGT > HDV > MDDT > HDT > LDT > TAXI > MDV > PC, and ammonia EFs were the lowest when the vehicle speed was around 48 km/ h. Total ammonia emissions on weekdays were slightly higher than on weekends, but were not significant, although there are restrictions during the week. And ammonia emissions from ordinary roads were the highest
