| 1 | Effect of artificial aeration on the performance of vertical-flow constructed wetland treating heavily polluted river water显示文摘Three lab-scale vertical-flow constructed wetlands(VFCWs),including the non-aerated(NA),intermittently aerated(IA) and continuously aerated(CA) ones,were operated at different hydraulic loading rates(HLRs) to evaluate the effect of artificial aeration on the treatment efficiency of heavily polluted river water.Results indicated that artificial aeration increased the dissolved oxygen(DO) concentrations in IA and CA,which significantly favored the removal of organic matter and NH 4 +-N.The DO grads caused by intermittent aeration formed aerobic and anoxic regions in IA and thus promoted the removal of total nitrogen(TN).Although the removal efficiencies of COD Cr,NH 4 +-N and TN in the three VFCWs all decreased with an increase in HLR,artificial aeration enhanced the reactor resistance to the fluctuation of pollutant loadings.The maximal removal efficiencies of COD Cr,NH 4 +-N and total phosphorus(TP)(i.e.,81%,87% and 37%,respectively) were observed in CA at 19 cm/day HLR,while the maximal TN removal(i.e.,57%) was achieved in IA.Although the improvement of artificial aeration on TP removal was limited,this study has demonstrated the feasibility of applying artificial aeration to VFCWs treating polluted river water,particularly at a high HLR. | Huiyu Dong Zhimin Qiang Tinggang Li Hui Jin Weidong Chen | 2012 | Journal of Environmental Sciences2012，24，4： | 38 |

| 7 | Evaluation on High-temperature Adhesion Performance of Hot-applied Sealant for Asphalt Pavement显示文摘In order to investigate the high-temperature performances of the asphalt pavement hot-applied sealant, as well as to reduce failures of the sealant pullout, the softening point test and the flow test(two existing methods for evaluating high-temperature performances) were conducted. It was found that both tests could not accurately reflect the adhesion performances of the sealant at high temperatures. For this purpose, the adhesion test for PSAT(pressure sensitive adhesive tape) has been taken as a reference to develop a device that is suitable for evaluating the adhesion performances, by modifying relevant test parameters according to the road conditions at high temperatures. Thirteen common sealants were tested in the modified adhesion test, softening point test and f low test. The experimental results show that no significant correlation(p>0.05) exists between the adhesion value, softening point, adhesion value and flow value; while a significant correlation(p<0.05) exists between the softening point and flow value. The modified adhesion test is efficient in distinguishing the hightemperature adhesion performances of different sealants, and can be used as a standard method for evaluating such performances. | 李峰 LI Tinggang SHI Xiaopei | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，6： | 1 |
