| 中文摘要 |
| 国家修订发布了GB 4915-2013《水泥工业大气污染物排放标准》，新建企业自2014年3月1日起实施，现有企业自2015年7月1日起实施. 在修订过程中，如何确定可行的大气污染物排放控制水平，成为标准限值确定的关键. 标准编制组系统调查分析了我国水泥工业污染排放现状、污染控制技术应用情况、环境管理需求、国外标准控制水平等，提出了可行的排放控制要求. 新标准扩大了标准适用范围，增加了污染物控制项目，提高了颗粒物、NOx等指标的排放控制要求，同时增加了适用于重点地区的大气污染物特别排放限值. 新标准的实施将成为水泥工业污染防治、总量减排、调整产业结构、优化布局的重要抓手，新标准将促进水泥工业生产工艺和污染治理技术的进步. |
| 英文摘要 |
| The revised National Emission Standard of Air Pollutions for Cement Industry has been issued, which will be effective for the new enterprises and the existing enterprises on Mar. 1st, 2014 and July 1st, 2015, respectively. In the process of revision, the key technical issues on determination of standard limits was how to determine the feasible emission control level of air pollutions. Feasible emission control requirements were put forward, according to air pollutants emission, technologies, environmental management requirements and foreign standards, etc. The main contents of the revised standard include expanding the scope of application, increasing the pollutants, improving the particulate and NOx emissions control level, and increasing special emission limits applied to key areas of air pollutants. The standard will become the gripper of pollution prevention, total emission reduction, structural adjustment and optimization of the layout, and will promote scientific and technical progression for the cement industry. |
