摘要
污泥作为建材既解决了环境污染又可缓解资源短缺等问题,但污泥中所含的重金属及有机物等却限制了污泥的资源化利用。因此文章分析了重金属、有机物等的形成及控制因素。通过调研分析得出,焚烧温度、燃烧气氛和添加剂等可在一定程度上控制灰渣和飞灰中的重金属含量;而燃烧参数、添加剂以及烟气净化等处置则可较好的控制二噁英的生成。
The environmental pollution and resource shortage will ease up if the municipal sludge to be used as construction materials. But the heavy metal and organic matter limited the resource utilization of municipal sludge. There for, In the paper, formation and control factors of heavy metal and organic matter was analyzed. It was found that the heavy metal content in the ash residue and fly ash can be controled by the burned temperature, combustion atmosphere and additive; incineration temperature , combustion parameter, dditive and flue gas cleaning will have a better control the generation ofdioxin.
