中文摘要：

这研究为煤床的处理在中国介绍第一个示范工程甲烷(CBM ) co-produced 水并且再循环。工作试图为解决 CBM 抽取水的污染问题提供一个研究和革新底。反向的渗透(RO ) 单位被用于 CBM co-produced 水的处理。结果显示那系统操作是稳定的，全部的溶解固体(TDS ) 的移动效率象 97.98% 一样高，并且 Fe， Mn，和 F 几乎完全被移开。没有在对待的水里检测的推迟的固体(SS ) 。而且，为 RO 膜分离过程的一个模型被开发描述在关键物理 quantitiesmembrane 长度，流动速度，盐集中，开车压力和水恢复率，和水之间的量的关系恢复限制方程基于质量，平衡被开发。这个模型为 RO 系统设计和优化提供理论支持。CBM co-produced 水里的 TDS 被移开满足中国的喝的水标准和地下水质量标准并且能被用作喝水，灌溉水，并且家畜流水。另外，为 CBM co-produced 水的处理的费用被估计，并且 RO 技术是一个有效、划算的处理方法移开污染物质。

英文摘要：

This study presents the first demonstration project in China for treatment of coal-bed methane（CBM） co-produced water and recycling.The work aims to provide a research and innovation base for solving the pollution problem of CBM extraction water.The reverse osmosis（RO） unit is applied to the treatment of CBM co-produced water.The results indicate that system operation is stable,the removal efficiency of the total dissolved solids（TDS） is as high as 97.98%,and Fe,Mn,and F-are almost completely removed.There is no suspended solids（SS） detected in the treated water.Furthermore,a model for the RO membrane separation process is developed to describe the quantitative relationship between key physical quantities-membrane length,flow velocity,salt concentration,driving pressure and water recovery rate,and the water recovery restriction equation based on mass balance is developed.This model provides a theoretical support for the RO system design and optimization.The TDS in the CBM co-produced water are removed to meet the ＂drinking water standards＂ and ＂groundwater quality standards＂ of China and can be used as drinking water,irrigation water,and livestock watering.In addition,the cost for treatment of CBM co-produced water is assessed,and the RO technology is an efficient and cost-effective treatment method to remove pollutants.
