2017-08-22 10:13:55   中国青年网

人民网北京8月22日电(记者 高星)记者从北京市环保局获悉,2017年7月,北京全市PM2.5月均浓度为52微克/立方米,同比下降24.6%,继3-6月后,再次实现历史同期最低。截至7月底,全市PM2.5累计浓度为64微克/立方米,为近五年最低,同比下降1.5%,较2013年同期下降34.7%。

截至目前,“清空计划”部分重点任务提前完成。7月份,4000蒸吨燃煤锅炉清洁能源改造、报废转出30万辆高排放老旧机动车、淘汰退出500家一般制造业企业等重点减排工作提前完成。

“控车减油”方面,截至7月底,报废转出老旧机动车30万辆,已提前完成全年任务。加强对外埠进京车辆检查执法,一是围绕主要进京道路以及五、六环路等区域周边,针对重型柴油车、高排放老旧车、货车闯禁行行为,开展集中专项整治行动,7月份共现场查处外埠车辆违反限制通行3.6万起。二是环保、商务、质监部门加大对加油站柴油及车用尿素、油气回收在线监控改造等的抽查、夜查力度,并对外埠进京柴油车油箱中柴油质量进行抽测。三是7月全市共抽查重型柴油车9.7万辆次,环比增加10.3%;查处违规车2473辆次,处罚金额127万元。此外,环保、质监、安监、商委联合印发了加油站油气回收在线监控改造的通知,要求年销售汽油量大于2000吨(含)的加油站应开展油气回收在线监控改造工程;其中,大于5000吨(含)的,要在2017年12月底前完成改造。

“清煤降氮”方面,截至7月底,农村700个村煤改清洁能源中“煤改电”522个村外网工程已完工79%;“煤改气”178个村外部管网84%开始施工;户内设备进场施工率62%。燃煤锅炉清洁能源改造工程在施9965蒸吨、完成4301蒸吨。燃气锅炉低氮改造已完成8400蒸吨,占全年任务的84%。

“治污减排”方面,开展了疏解整治促提升专项行动,清退一般制造业企业539家,提前超额完成任务。

北京市环保局、市政府督查室等牵头对上半年空气质量排名靠后、工作落实不力、监管存在问题的14个街乡镇主要领导进行了集中约谈,指出各街乡镇突出的环境问题,提出整改要求及时限。下一步,北京将针对重型车管控、“散乱污”整治、提升精细化水平、加快推进“清煤降氮”配套管线建设等重点难点问题解决,聚焦重点、加大力度,推进空气质量进一步改善。
