Optimal Absorbent Evaluation for the CO2 Separating Process by Absorption Loading,Desorption Efficiency,Cost, and Environmental Tolerance

The CO₂ absorption capacities of potassium glycinate, potassium sarcosinate (choline, proline), mono-ethanolamine (MEA), and tri-ethanolamine were evaluated to find the optimal absorbent for separating CO₂ from gaseous products by a CO₂ purification process. The absorption loading, desorption efficiency, cost, and environmental tolerance were assessed to select the optimal absorbent. MEA was found to be the optimum absorbent for separating the CO₂ and H₂ mixture in gaseous product. The maximum absorption loading rate was 0.77 mol CO₂ per mol MEA at temperature of 20°C and absorbent concentration of 2.5 mol/L, whereas desorption efficiency was 90% by heating for 3 h at 130°C. MEA was found to be an optimal absorbent for the purification process of CO₂ during gaseous production.

南宁城市大气污染对人体健康的危害及治理对策

南宁市大气属煤烟型污染 ,大气的主要污染物为SO2 、NOx、TSP、降尘 ,虽然随着环境管理和污染治理工作的加强 ,污染物浓度逐年下降 ,但是工业区大气污染仍然较重。污染物流行病学调查显示 :工业区癌症和呼吸系统疾病死亡率均高于全市平均水平 2倍左右 ,城区又高于郊区 2倍 ,大气污染综合指数与呼吸内科门诊就诊人数呈正相关。用邓聚龙的灰色系统理论分析得知污染物对癌症和呼吸系统疾病死亡率有关联 ,关联度从大到小排序为 :TSP >降尘 >SO2 >NOx ,最后提出了大气污染治理的对策。

对低影响开发与海绵城市的再认识

海绵城市建设是在继承我国古代先贤智慧和参考国外经验,系统总结我国雨洪管理领域长期研究和实践经验的基础上,结合我国城市水系统实际问题提出的城市发展方式,其核心是构建基于绿灰结合的现代城市雨洪控制系统,通过"渗、滞、蓄、净、用、排"综合措施,实现"治涝"与"治黑"等多重目标。低影响开发是海绵城市建设的重要指导思想,也是海绵城市核心技术体系的重要组成部分。正确认识低影响开发与海绵城市的内涵与联系,对于进一步在全国范围内落实低影响开发建设模式,科学推进海绵城市建设具有重要意义。     

基于洪涝风险分析的纽约市城市绿地规划设计及其对中国的启示

1968年美国开始推行洪涝保险计划,不断完善对洪涝风险的研究,并逐步形成了一套相对完善的洪泛区管理体系,而洪涝风险分析在洪涝保险、城市规划、土地开发、应急管理等领域广泛应用。纽约市在经历了多次飓风侵害,尤其是2012年飓风桑迪（Sandy）之后,意识到城市绿地在极端暴雨事件时对雨洪调蓄的重要作用,经过持续的研究实践,提出了基于洪涝风险分析的城市绿地规划设计要求。基于总结美国纽约市在飓风桑迪影响下对洪涝风险图的调整,及其对城市绿地规划设计相关要求,提出其对我国洪涝风险管控及城市绿地规划设计的启示。
