| 1 | Phosphate removal from wastewater by model-La(Ⅲ)zeolite adsorbents显示文摘Phosphorus is one of the primary nutrients which leads to eutrophication and accelerates aging process in enclosed water bodies. Because of the poor phosphorus selectivity of other adsorbents, the novel La(III)-modified zeolite adsorbent (LZA) was prepared by modifying 90 nm zeolite with lanthanide to selectively remove phosphate in the presence of various omnipresent anions, such as sulfates, bicarbonates, and chlorides. Through batch and fixed bed operation, the following optimum conditions were obtained: concentration of lanthanum chloride solution 0.05 mol/L; solid/liquor ratio 1/25; pH 10; calcination temperature 550°C; time 1 h. The value of the Freundlich model constants Kf and 1/n were found to be 16.76 mg/L and 0.2209, respectively. In addition, when calculated at pH 6.0, distribution coefficient KD could be as high as 36.6. Furthermore, in the alkaline pH range, solution of 0.8 mol/L NaCl was used to regenerate the saturated LZA, which could reach the high regeneration efficiency as high as 100%. Because of the good selectivity and regenerability of LZA, it might serve as a potential way for advanced phosphate removal from the sewage containing other anions. | NING Ping BART Hans-Jorg LI Bing LU Xiwu ZHANG Yong | 2008 | Journal of Environmental Sciences2008，20，6： | 30 |
| 2 | Formation and evolution of the tertiary carbonate reefs in the Madura Strait Basin of Indonesia显示文摘Analysis of 2 D seismic data over 4 500 km in length from the Madura Strait Basin in the East Java Sea reveals seismic re?ection characteristics of reefs and associated sedimentary bodies, including asymmetrical or symmetrical dome re?ections, slope progradational re?ections, chaotic re?ections and discontinuous strong re?ections inside the reef, which onlap the ?ank of the reef. It is concluded that the developmental paleo-environment of most reefs is mainly conducive to shallow marine carbonate platform facies and platform margin facies, based on well core data, variations in seismic facies and strata thickness.The formation and evolution of all reefs are primarily in?uenced by the tectonic framework of the Madura Strait Basin. Platform margin reefs are principally controlled by two types of structures: one is a series of E-W trending Paleogene normal faults, and the other is an E-W trending Neogene inversion structures. In addition, wave actions, tidal currents and other ocean currents play an accelerated role in sorting, rounding and redeposition for the accumulation and evolution of reefs. Tertiary reefs in the MSB can be divided into four types: 1) an open platform coral reef of Late Oligocene to Early Miocene, 2) a platform margin coral reef controlled by normal faults in Late Oligocene to Early Miocene, 3) a platform margin Globigerina moundreef controlled by a 'hidden' inversion structure in Early Pliocene, and 4) a platform margin Globigerina mound-reef controlled by thrust faults in the early Pliocene. Patterns of the formation and evolution of reefs are also suggested. | RAN Weimin LUAN Xiwu LU Yintao LIU Hong YANG Jiajia ZHAO Yang HE Wenchang YAN Zhonghui | 2019 | Journal of Oceanology and Limnology2019，37，1： | 3 |

| 6 | Effect of Mg content on the structural and optical properties of Mg_xZn_(1-x)O alloys显示文摘Mgx Zn1–x O thin films with x = 0, 0.11, 0.28, 0.44, 0.51, and 0.65 were grown by plasma-assisted molecular beam epitaxy on (0001) sapphire substrates. X-ray diffraction measurement reveals that phase separation of the Mgx Zn1–x O films occurred at x =0.44 and 0.51. Optical absorption spectra show that the absorption edges of the films shift to high-energy side with increasing Mg contents. In resonant Raman spectra, multiple-order Raman peaks originating from ZnO-like longitudinal optical phonons were observed. Moreover, the blue shift and the full width at half maximum of Raman scattering peaks increase continuously with x increasing from 0 to 0.28, which indicates that Zn is substituted by Mg in hexagonal lattice. | WU ChunXia LU YouMing SHEN DeZhen FAN XiWu | 2010 | Chinese Science Bulletin2010，55，1： | 1 |

| 17 | Microbial community characterization,activity analysis and purifying efficiency in a biofilter process显示文摘The growth and metabolism of microbial communities on biologically activated carbon(BAC) play a crucial role in the purification of drinking water.To gain insight into the growth and metabolic characteristics of microbial communities and the efficiency of drinking water treatment in a BAC filter,we analyzed the heterotrophic plate count(HPC),phospholipid,dehydrogenase,metabolic function and water quality parameters during start-up and steady-state periods.In the start-up process of the filter with natural biofilm colonization,the variation in heterotrophic plate count levels was S-curved.The total phospholipid level was very low during the first 5 days and reached a maximum value after 40 days in the filter.The activity of dehydrogenase gradually increased during the first 30 days and then reached a plateau.The functional diversity of the microbial community in the filter increased,and then reached a relatively stable level by day 40.After an initial decrease,which was followed by an increase,the removal rate of NH4+-N and COD Mn became stable and was 80% and 28%,respectively,by day 40.The consumption rate of dissolved oxygen reached a steady level after 29 days,and remained at 18%.At the steady operation state,the levels of HPC,phospholipid,dehydrogenase activity and carbon source utilization had no significant differences after 6 months compared to levels measured on day 40.The filter was shown to be effective in removing NH4+-N,NO2--N,COD Mn,UV 254,biodegradable dissolved organic carbon and trace organic pollutants from the influent.Our results suggest that understanding changes in the growth and metabolism of microorganisms in BAC filter could help to improve the efficiency of biological treatment of drinking water. | Hong Xiang Xiwu Lu Lihong Yin Fei Yang Guangcan Zhu Wuping Liu | 2013 | Journal of Environmental Sciences2013，25，4： | 1 |
| 18 | Kinetics and capacities of non-reactive phosphorus (NRP) sorption to crushed autoclaved aerated concrete (CAAC)显示文摘With growing interest in resource recovery and/or reuse,wastematerials have been considered a promising alternative for phosphorus(P)adsorption because they are low-cost and easily accessible.Crushed autoclaved aerated concrete(CAAC),as representative construction waste,has been extensively studied for P removal in ecological technologies such as treatment wetlands.However,most of the previous studies focused on the adsorption of orthophosphate,namely reactive phosphorus,and lacked attention to non-reactive phosphorus(NRP)which is widely present in sewage.This study presents the first investigation on the potential and mechanism of CAAC removing four model NRP compounds.Adsorption isotherm and kinetics of NRP onto CAAC indicate that the removal of NRP was a chemisorption process and also involved a two-step pore diffusion process.The desorption experiment shows that different NRP species showed varying degrees of desorption.Most NRP was irreversibly adsorbed on CAAC.Among the model compounds considered in this study,the adsorption capacity and hydrolysis rate of organophosphorus were much less than that of inorganic phosphorus.Moreover,the adsorption of different NRP species by CAAC in the mesocosm study was different from the results of laboratory adsorption experiments,and the possible biodegradation was essential for the conversion and removal of NRP.The findings confirmed the validity of CAAC for NRP removal and the potential advantages of CAAC in terms of costs and environmental impact.This study will contribute to a better understanding of NRP conversion and environmental fate and that can be the basis for a refined risk assessment. | Shuting Shen Xiang Li Zhuofan Geng Xiwu Lu | 2023 | Journal of Environmental Sciences2023，，5： | 0 |

Constant improvement is being made in the development of ecological city. However, building ecological city is an enormous project that calls for a huge amount of capital. The government fund is far from adequate. This paper probes into the fund issue and discusses in detail the mechanism of investment and financing in building ecological city from various aspects such as diversification of the investment subjects and the modes of financing. | Dai Shiming Lu Xiwu Qin Xing | 2008 | Chinese Journal of Population,Resources and Environment2008，6，1： | 0 |
| 20 | Controls on the Gas Hydrate Occurrence in Lower Slope to Basin-Floor,Northeastern Bay of Bengal显示文摘High resolution seismic data and newly acquired logging data reveal the presence of gas hydrates in the deep-water area in the northeastern Bay of Bengal.Bottom Simulating Reflectors(BSRs)appear at 430 ms beneath the seafloor,with the features of typical gas hydrates reported elsewhere except for some discontinuity.The BSR distribution is closely related to the position of anticline structures and turbidite channels.Anticlines provide conduits for the upward migration of gases from deeper intervals,while the turbidite sands within channels act as reservoirs for gas hydrate accumulation.High sedimentation rates in the Bengal Fan were ge-nerally favorable to produce a great amount of methane gas,providing favorable preconditions for the formation of gas hydrates.The discovery of gases in adjacent area indicates the contribution of the biogenic gas to the formation of gas hydrates.Meanwhile,seismic sections provide the evidence for the potential thermogenic gas kitchen in deep intervals.The anticline structures and the associated vertical fractures may constitute vertical fluid flowing conduits,which hydraulically connect the two deeper thermogenic petroleum systems(i.e.,rifting and Eocene-Oligocene source rocks)with the turbidite reservoirs and thus facilitate the fluid migration from the sources to the reservoirs,generating favorable conditions for gas-hydrate accumulation in such foreland setting. | LU Yintao LUAN Xiwu SHI Boqing FAN Guozhang RAN Weimin XU Ning WANG Haiqiang SHAO Dali DING Liangbo WANG Xingxing | 2022 | Journal of Ocean University of China2022，21，4： | 0 |
