[独家]水泥脱硝是主要大气污染物减排工程的硬任务

2014-07-03 13:31:32

按《水泥工业大气污染物排放标准》(GB 4915-2013)规定,现有水泥企业自2015 年7 月1 日起,其大气污染物排放控制按新标准的规定执行。因此,水泥企业实施脱硝,从时间上看,要比行动方案实施期限得提前半年才行。从任务量上看,现有企业从明年7月1日起必须按新标准的规定执行。

  据《中国环境报》报道,7月1日,根据环境保护部党组部署,2014年上半年主要污染物总量减排核查核算视频会议在京召开,环境保护部副部长翟青安排部署上半年全国减排核查核算工作。翟青说,从国家对“十二五”规划纲要中期评估情况看,经济社会发展绝大多数指标进展良好,但节能减排情况不理想。前3年全国氮氧化物排放总量累计下降2%,仅完成5年总任务的20%,部分地区总体进度滞后,压力较大。针对严峻的节能减排形势,国务院召开节能减排和应对气候变化工作会议,国务院办公厅印发《2014~2015年节能减排低碳发展行动方案》,明确了8个方面30条政策措施。(开展)半年核查的主要目的是查找问题,研判形势,推进工作。

  翟青强调,今年政府工作报告已经公布了主要污染物总量减排目标,列出了电力脱硝1.5亿千瓦、除尘改造1.8亿千瓦,淘汰黄标车及老旧车600万辆,以及淘汰5万台燃煤小锅炉等3项重点任务。

  李总理在今年政府工作报告明确了今年九项重点工作,其中第九项为努力建设生态文明的美好家园。李总理说,生态文明建设关系人民生活,关乎民族未来。雾霾天气范围扩大,环境污染矛盾突出,是大自然向粗放发展方式亮起的红灯。必须加强生态环境保护,下决心用硬措施完成硬任务。

  对2014年上半年主要污染物总量减排核查核算就是为完成生态环境保护硬任务所采取的硬措施之一。《2014~2015年节能减排低碳发展行动方案》文件所下达到各地区的三项硬任务是,燃煤锅炉淘汰任务、主要大气污染物减排工程任务、黄标车及老旧车辆淘汰任务。在“主要大气污染物减排工程任务”中,有三项硬指标,火电脱硝、钢铁烧结机脱硫和水泥脱硝。也就是说水泥脱硝列进了主要大气污染物减排硬任务、硬指标。即必须要完成6亿吨熟料产能生产线脱硝任务。行动方案也已将水泥须完成的脱硝任务指标分解到28个省(区、市)和新疆建设兵团。

  另一方面,按《水泥工业大气污染物排放标准》(GB 4915-2013)规定,现有水泥企业自2015 年7 月1 日起,其大气污染物排放控制按新标准的规定执行。因此,水泥企业实施脱硝,从时间上看,要比行动方案实施期限得提前半年才行。从任务量上看,现有企业从明年7月1日起必须按新标准的规定执行。但到目前,完成脱硝的生产线占比并不大,这无疑表明,水泥脱硝任务的量事实上应大于6亿吨,摆在水泥工业面前的脱硝任务更重。

  翟青说,国务院办公厅已将任务分解落实到各地。这是必须完成的硬任务,是国务院督办的重点,核查组将对各地3项任务落实情况重点督查。因此,水泥工业主要大气污染物减排工程任务的落实情况,必然是各地区节能减排重点督查的内容。

  还没有实施脱硝减排工程的水泥企业应该在各地区的统一安排下,抓紧落实到位,为各地区完成主要大气污染物减排硬任务尽到责任。
