作为二恶英排放量较大的国家之一，二恶英的控制是我国面临的一个重大挑战。城市固体废物焚烧在废物管理中发挥着越来越重要的作用，应被视为二恶英排放的一个高度优先来源。我国城市生活垃圾焚烧过程中二恶英的排放量远高于发达国家，这与我国在焚烧技术和烟气净化技术方面存在的差距有关。此外，目前的管理政策和做法也是造成这一问题的重要原因。我们建议降低二恶英排放标准，加强飞灰管理，并改善法规执行，以减少城市固体废物焚烧过程中二恶英的排放。我们亦建议当局考虑其他管制二恶荚的策略，并呼吁在废物管理方面，扩大经济手段，以减少废物的产生，从而减少焚化的需要。
As one of the countries with large amounts of dioxin releases, the control of dioxins is a major challenge for China. Municipal solid waste (MSW) incineration should be considered a high priority source of dioxin emissions because it is playing an increasingly more important role in waste management. MSW incineration in China has much higher emission rates of dioxins than in the developed countries, partially resulting from the gaps in the technologies of incineration and flue gas cleaning. Moreover, the current management policies and practices also contribute significantly to the problem. We recommend lowering dioxin emission standard, strengthening fly ash management, and improving regulation enforcement to reduce dioxin releases into the environment from MSW incineration. We also propose that alternative strategies should be considered on dioxin control and call for an expansion of economic instruments in waste management to reduce waste generation and thus the need for incineration.
