Detoxification method for fly ash washing and mixing and biomass incineration

LI CHUNPING / XU JIANYI

The invention relates to the field of environmental protection, in particular to a method for fly ash washing and mixing and biomass incineration detoxification. The invention provides a harmless treatment and comprehensive utilization technology of the fly ash, and the fly ash is treated by utilizing a fly ash washing and mixing technology and a biomass incineration detoxification technology, so that the harmless treatment of the fly ash is realized, and the environmental problem is solved. According to the method, a fly ash harmless treatment process is adopted, dioxin is decomposed, and the purpose of thoroughly detoxifying dioxin is achieved; after heavy metals are treated, the leaching toxicity index can completely meet the national heavy metal leaching toxicity standard requirements; the fly ash is thoroughly and harmlessly treated, stockpiling and landfill are not needed, land resources are saved, and secondary pollution of soil and water is avoided.

本发明涉及环保领域，具体关于一种飞灰水洗拌和生物质焚烧脱毒的方法；本方法提供了一种飞灰的无害化处理及综合利用技术，以利用飞灰水洗拌和生物质焚烧脱毒技术处理飞灰，实现飞灰的无害化，解决环境问题。本方法采用的飞灰无害化处理工艺，将二噁英分解，达到二噁英彻底解毒目的；对重金属处理后，浸出毒性指标能够完全达到国家重金属浸出毒性标准要求；实现了飞灰实现彻底无害化处理，无需堆存及填埋，节约土地资源，避免了土壤及水体的二次污染。
