摘要
在以柴油为燃料的熔融炉中熔融固化垃圾焚烧飞灰,并对固化效果进行检验。进一步探讨了不同环境对飞灰固化效果的影响规律。结果表明飞灰熔融固化后就不再具有浸出毒性的危险废物;酸性(pH≤4.5)和碱性(pH≥11.5)环境对固化效果的影响比较大;潮湿的环境对固化效果无明显影响。
Fly ash from refuse incineration is solidified in a melting furnace that takes diesel fuel as its fuel, the solidifying effect is examined.The influence of different environments on the solidifying effect is also explored.The results show that the fly ash has no toxicity after its melt solidification; acidic(pH≤4.5) and alkaline (pH≥11.5) environments have a greater effect on the solidification, whereas a wet one has no obvious effect on the solidification.
