Waste incineration fly ash harmless treatment curing agent and waste incineration fly ash harmless treatment method
According to the invention, the chemical raw materials adopted by the harmless treatment curing agent are conventional materials, the additive is added into the waste incineration fly ash according toa certain proportion, and dioxin in the fly ash can be in a stable state at the temperature of 400 DEG C or below. Heavy metal elements such as chromium in the fly ash can exist in a stable compoundform, so that the leaching toxicity of the waste incineration fly ash is reduced, and the secondary pollution possibility of the waste fly ash in the utilization process is greatly reduced. After thefly ash solidified mixture pellet particles are added into the sintering material according to a certain proportion to be sintered, the strength indexes of the sintering material block all reach the national standard, the leaching toxicity of heavy metal chromium completely reaches the national standard, and dioxin can be completely decomposed for detoxification. Meanwhile, the sintered material block is used as a metallurgical raw material to realize resource utilization, so that harmless and resourceful treatment of the waste incineration fly ash is realized. The device is good in market prospect, high in economic practicability and worthy of market popularization.
本发明的无害化处理固化剂采用的化工原料为常规物料，将本添加剂按一定比例加入垃圾焚烧飞灰中，能使飞灰中的二噁英在400℃以下处于稳定状态。还能使飞灰中的铬等重金属元素以稳定的化合物形态存在，从而降低垃圾焚烧飞灰的浸出毒性，极大地降低垃圾飞灰在利用过程中的二次污染可能性。通过对飞灰固化混合料球团颗粒按一定比例添加到烧结料中烧结处置后，烧结料块的强度指标均达到国家标准，重金属铬浸出毒性完全达到国家标准，二噁英可实现完全分解解毒。同时，烧结料块用作冶金原料实现资源化利用，从而实现垃圾焚烧飞灰的无害化和资源化处理。本发明市场前景好，经济实用性强，值得进行市场推广。
