1防城港近岸海域及河口溶解态重金属污染特征显示文摘为了解近岸海域及河口重金属的分布特征和污染状况,测定了采自防城港近岸海域及河口的25个表层水样的溶解态重金属(Zn、Cu、Pb、Cd、As、Hg)含量,并分析了其含量特征及空间分布特点,探讨了重金属与主要环境因子之间的相关性,并按单项污染指数法及综合指数WQI法对其进行评价。结果表明,研究区域溶解态重金属含量从高到低的顺序依次是Zn>Cu>Pb>As>Cd>Hg,除Zn、Pb元素外,Cu、Cd、As、Hg元素平均含量均低于国家一类海水水质标准。重金属与环境因子相关性分析表明,p H对Zn含量的影响比较显著,盐度对As、Zn、Pb含量的影响比较显著,温度对Cu、As、Hg含量的影响比较显著,而溶解氧对Cu、Pb含量的影响比较显著。从单项污染指数来看,研究区Zn、Pb均受到一定程度的污染,而西湾和东湾在一定程度受到Hg的污染;从综合污染指数来看,除防城江上游区域外,防城港近岸水域溶解态重金属综合污染指数均小于1,属无污染。王毅 王少鹏 王英辉 PHANMAHA Alek 2018广西大学学报(自然科学版)2018,43,5:9
2超临界CO_2增强热卤水开采模型研究显示文摘面对全球气候变化和能源紧缺的巨大压力,CO2地质利用技术成为研究的焦点。为了实现CO2减排及资源化利用,提出了利用超临界CO2增强卤水提取和地热能开采的CO2地质利用集成系统的概念。通过建立CO2注入热卤水储层的质量平衡模型,分析了不同流量的卤水生产、CO2注入以及储层边界流对储层变化的影响,初步评估了该系统的CO2封存量、卤水提取量以及储层流体组成变化的时间尺度。研究表明,注入CO2提供了热卤水层的压力维持,促进卤水和地热资源的可持续开采,对于江陵凹陷研究区9×10^8 m^3的储层有效体积,注入9.95×10^6 t CO2可提取17.12×10^6 t卤水,时间尺度超过30a。对于50~1 000kg/s的卤水生产速度,可以产生0.9~18.8 MW电力。同时,该技术增加了CO2的封存容量和效率,有利于CO2大规模安全封存,经济和环境效益显著。杨国栋 李义连 马鑫 Atrens Aleks 倪浩 2014地质科技情报2014,33,6:2

10Reactive Transport Modeling of Long-Term CO2 Sequestration Mechanisms at the Shenhua CCS Demonstration Project,China显示文摘Carbon dioxide injection into deep saline aquifers results in a variety of strongly coupled physical and chemical processes. In this study, reactive transport simulations using a 2-D radial model were performed to investigate the fate of the injected CO_2, the effect of CO_2-water-rock interactions on mineral alteration, and the long-term CO_2 sequestration mechanisms of the Liujiagou Formation sandstone at the Shenhua CCS(carbon capture and storage) pilot site of China. Carbon dioxide was injected at a constant rate of 0.1 Mt/year for 30 years, and the fluid flow and geochemical transport simulation was run for a period of 10 000 years by the TOUGHREACT code according to the underground conditions of the Liujiagou Formation. The results show that different trapping phases of CO_2 vary with time. Sensitivity analyses indicate that plagioclase composition and chlorite presence are the most significant determinants of stable carbonate minerals and CO_2 mineral trapping capacity. For arkosic arenite in the Liujiagou Formation, CO_2 can be immobilized by precipitation of ankerite, magnesite, siderite, dawsonite, and calcite for different mineral compositions, with Ca^(2+), Mg^(2+), Fe^(2+) and Na^+ provided by dissolution of calcite, albite(or oligoclase) and chlorite. This study can provide useful insights into the geochemistry of CO_2 storage in other arkosic arenite(feldspar rich sandstone) formations at other pilots or target sites.Guodong Yang Yilian Li Aleks Atrens Danqing Liu Yongsheng Wang Li Jia Yu Lu 2017Journal of Earth Science2017,28,3:1
