钢铁大气污染物排放标准
钢铁工业是我国重要的基础产业之一，但同时也是大气污染的重要来源之一。
钢铁生产过程中排放的污染物对环境和人体健康造成了严重影响。
为了控制钢铁大气污染物排放，我国制定了一系列的排放标准。
首先，钢铁企业应当建立健全的污染物排放监测系统，对排放的二氧化硫、氮氧化物、颗粒物等污染物进行实时监测，并及时报送监测数据。
这有助于监管部门及时了解钢铁企业的排放情况，及时采取措施进行调控。
其次，钢铁企业应当配备先进的污染治理设施，对废气进行有效处理。
采用高效除尘设备、脱硫脱硝设备等，以减少二氧化硫、氮氧化物等有害气体的排放。
此外，还可以通过技术改造，提高炼铁炉、炼钢炉等设备的能效，减少燃烧排放。
另外，钢铁企业应当严格执行国家和地方的大气污染物排放标准，对超标排放的企业进行处罚。
同时，加强对钢铁企业的监管和检查，确保其排放达标。
对于违法违规的企业，要依法依规进行处罚，直至关停整顿。
此外，政府也应当加大对钢铁行业的环保政策支持力度，鼓励企业进行绿色技术研发和应用。
通过财政补贴、税收优惠等措施，引导企业加大环保投入，推动钢铁行业向绿色、低碳方向发展。
总的来说，控制钢铁大气污染物排放需要企业自觉遵守政策法规，加强污染治理设施建设和运行维护，同时也需要政府的监管和政策支持。
只有通过全社会的努力，才能有效减少钢铁大气污染物排放，改善环境质量，保护人民健康。
美国发电厂污染物排放最新标准根据《洁净空气法案》（CAA）第111章和112章规定和要求，2011年12月16日，美国环保署签署了一项电厂减排有毒空气污染物的法令，包括燃煤燃油电厂锅炉有毒空气污染物排放国家标准（NESHAP）和新燃烧化石燃料电站、工商业设施锅炉性能标准（NSPS）。
2012年4月16日生效。
特别是，汞及空气污染物排放标准（MATS）规定现有和新建的燃煤、燃油锅炉都要实行减排；同时修订了新排放源性能标准。
英文缩写解释：NESHAP: National Emission Standards for Hazardous Air Pollutants 有毒空气污染物国家排放标准NSPS：New Source Performance Standards 新排放源性能标准CAA: Clean Air Act 洁净空气行动MATS: Mercury and Air Toxics Standards：汞及空气污染物标准EGUs： Electric utility steam generating units 蒸汽发电设备MCAT：Maximum Achievable Control Technology 最大限度控制技术Federal Register：联邦纪事一、燃煤和燃油发电机组有毒空气污染物排放国家标准《发电厂汞及空气污染物排放标准》与原来提议的基本相同。
不一样的几点：（1）调整了排放限制，包括利用可吸入颗粒物而不是总的颗粒物替代金属污染物；（2）对煤的分类进行了修改；（3）为了统一，改进监测系统（4）可以用多台机组的平均值；这是第一个燃煤和燃油电厂减少汞及其他空气污染物的国家清洁空气行动标准。
根据新标准，自２０１６年起，发电厂必须采用目前广泛使用并得到认证的污染控制技术，大幅度削减可吸入颗粒物、汞、砷、镍、硒、酸性气体、氰化物等有毒物质的排放。
发电厂是美国汞、砷、氰化物的最大排放源，50％汞和77％酸性气体排放来自电厂。
美国大气污染物排放标准体系特征及借鉴意义中国环境学会 2011年06月22日张旭，梅风乔* (环境科学与工程学院，北京大学，北京，100871) Email:*************.cn摘要：大气污染物排放标准是防治空气污染，限制污染物排放的关键措施。
美国的大气污染物排放标准体系以清洁空气法和联邦法规法典为依托，分为固定污染源和移动污染源两个子系，其中固定源标准体系中又以针对新建排放源的NSPS标准和针对有毒有害污染物的NESHAP标准为核心，对常规污染物的现有排放源通过州的实施计划进行控制落实。
整个标准体系技术导向明显，行业划分细致，注重公众健康，对于完善我国现行的大气污染物排放标准体系具有积极的借鉴意义。
关键词：大气污染物排放标准，体系特征，技术原则，行业，借鉴意义。
污染物排放标准是美国为达到环境质量标准所采取的技术强制措施[1]。
大气污染物排放标准主要内涵于清洁空气法(CAA，Clean Air Act)[2]和美国联邦法规法典(CFR，Code of Federal Regulation)[3]，属于法律的组成部分。
本文从排放标准所处的政策环境入手，凸显其整体的技术要素，并依固定污染源和移动污染源展开，分别探析其各自的特征，从而得出完善我国大气污染物排放标准体系的建议。
相关政策架构及技术体现[4]美国的清洁空气防治策略规定细致，层次分明。
基于保护人体健康的根本出发点，其以国家环境空气质量标准（NAAQS，National Ambient Air Quality Standard）为基础，结合州的实施计划（SIP，State Implementation Plan）、污染物排放标准、许可证制度等政策措施，对固定源和移动源分别进行控制，其中以排放标准对污染物浓度的减排作用尤为突出，有效地保证了整个大气环境质量。
如图1所示，美国的整个空气污染防治政策布局主要贯穿于横纵多条主线之间，充分体现出“技术导向”的根本特征：其一，从横向角度，图1的右侧主要是国家环境空气质量标准的体现。
