武绍贵讲到,要想取得良好的VOCs减排成效,不能急于一时之功,不能把末端治理当成“救命稻草”,必须追溯各个领域VOCs污染的相关环节,并形成一条完整的“污染管控链”,逐步形成一套成熟有效的VOCs环境管理体系。

治理难度大

VOCs是指参与大气光化学反应的有机化合物,包括非甲烷烃类、含氧有机物、含氯有机物、含氮有机物、含硫有机物等,是形成臭氧和细颗粒物(PM2.5)污染的重要前体物。
近年来,全国SO2、氮氧化物(NOx)、烟粉尘控制成效明显,但VOCs排放量仍呈增长趋势,对大气环境影响日益突出。VOCs排放还会导致大气氧化性增强,且部分VOCs会产生恶臭。为进一步改善环境空气质量,打好蓝天保卫战,迫切需要全面加强VOCs污染防治工作。

据武绍贵分析,从环境执法实务角度看,VOCs管控难度主要存在于三个方面。

首先,VOCs对臭氧污染的贡献机理复杂,且与PM2.5、NOX存在“1+1>2”的叠加污染关系,因此,只有“多管齐下”才能有效遏制臭氧污染;其次,涉VOCs行业类别和源项类型十分丰富、量大面广,与生产、流通、消费均息息相关,对于VOCs物料及所谓“重点源”的判断,在实践中经常会出现一些困难和争议;最后,已有的VOCs治理设施的原理不尽相同,理论去除效率差异很大,设计初装和稳定运行阶段的污染物降解效果往往也很难保持一致。在此基础上,现有的监测手段,特别是快速检测仪器,使用效果并不尽如人意,在技术层面限制了环境执法更高效的开展。
