Abstract :
In order to assess the feasibility of restoring sewage partial nitritation/anammox (PN/A) process using free nitrous acid (FNA) to treat flocculent sludge, the effect of different concentrations of FNA on the activities of ammonium oxidizing bacteria (AOB) and nitrite oxidizing bacteria (NOB) was studied. Besides, the variations of nutrient removal performance in the SBR reactor by twice FNA treatment were investigated. The results showed that NOB activity could be inhibited when the flocculent sludge treated by FNA of 0.45mgHNO2-N/L and the nitrite accumulation rate (NAR) reached 88.8%, but NOB activity recovered from the 8th day. While NOB activity could be significantly inhibited when the flocculent sludge treated by FNA of 1.35mgHNO2-N/L, and the NAR reached 89.1%. Meanwhile the activities of AOB was also inhibited, and NH4 +-N conversion rate decreased to 6.8%. By enhancing the ratio of aerobic time to anoxic time (t好/t缺: from 0.4~2.7) and increasing dissolved oxygen (DO: from 0.2~1.5mg/L), the AOB activity recovered, and NH4 +-N conversion rate reached 77.8%. But the activities of NOB was not recovered within 150days, and the NAR achieved 98.1%. With the stable achievement of nitritation, the nitrogen removal performance of the system gradually restored, the average effluent total inorganic nitrogen (TIN) was 8.2mg/L, and the average TIN efficiency was 84.1%. Therefore, the strategy by first treating flocculent sludge with higher FNA to inhibite both AOB and NOB, then increasing t好/t缺 and DO to restore AOB activity, could achieve the restoration of PN/A process. © 2019, Editorial Board of China Environmental Science.

Abstract :
作为世界最大的镁生产国和出口国,中国镁工业面临着温室气体减排的巨大挑战.研究分析了中国原镁生产过程温室气体排放随时间的变化,采用对数平均迪氏指数分解方法确定了影响温室气体排放的主要因素,从技术和政策方面提出了减缓温室气体排放的措施.研究结果表明,自2003-2013年,中国原镁产量增长了125%,而温室气体排放仅增长16%;吨镁能耗相关的温室气体排放从28.4t CO2eq降至6.6t CO2eq.自2009年开始,原镁生产的温室气体排放中,直接排放的比重为47%,已小于间接排放,说明中国镁工业在节能减排方面所做出的努力是卓有成效的.生产规模特别是国际市场对镁产品的需求是温室气体排放增长的主要贡献因素,而能源强度和能源结构是温室气体减排的主要促进因素.

Abstract :
The global warming of cement concrete pavement from raw material extraction to road construction was analyzed by the method of life cycle assessment. The characterization results showed that the procedure of producing material is the most important stage to emit greenhouse gas and it accounts for 98.5% of the global warming potential that caused by the material production and construction stage. For the materials used in different structure layers, surface layer is the biggest impact of greenhouse and accounts for 68.9% of the total impact caused by material used in constructing pavement. Therefore in the future, by using recycled materials or more environmental materials will be a good way to reduce environment impact. © (2015) Trans Tech Publications, Switzerland.

Abstract :
铝是国民经济建设和发展的关键基础材料,然而由其生产过程所产生的大量温室气体排放也逐渐成为政府关注的焦点.本研究计算了我国原铝生产不同年度的生命周期能耗和温室气体排放量,并分析了资源消耗和生产工序能耗等影响因素与温室气体排放的关联性.结果表明,在各年原铝生产的温室气体排放总量中,电力和阳极效应导致的排放所占比重分别为68.5%和7.9%,其他影响因素所占比重均低于6%;与温室气体排放关联度最高的3个影响因素依次是电耗、煤气燃烧和石灰石煅烧,其值分别为0.937、0.899和0.893;在目前铝电耗和阳极效应控制水平提升空间有限的情况下,降低煤气的消耗,提高石灰石的使用效率,是实现原铝生产温室气体减排的有效途径.

Abstract :
In order to study on seismic performance of fiber reinforced polymer confined hollow section column of different slenderness ratio, the RC rectangular hollow section columns with slenderness ratio of 4 and 8 were designed. Quasi-static test was carried out to the tested columns, and the failure characteristic, seismic performance and additional moment were analyzed. The experimental result shows that ultimate lateral displacement of FRP confined hollow section columns with slenderness ration of 8 is increased by 16%. However, the maximal lateral force and ultimate lateral force is increased about 5%; pinch-shrinking effect of confined tested column with slenderness ration of 4 is reduced, while the additional moment of confined tested column with slenderness ration of 8 is reduced. Besides, comparing the measured lateral force-displacement of the top of tested columns and rotation deformation-moment of plastic hinge region for FRP confined columns with simulated results, it is shown that the simulated results have good agreement with experimental results.
