Biological treatment method for waste incineration fly ash

The invention relates to the technical field of microorganisms, in particular to a biological treatment method for waste incineration fly ash. The invention provides a biological treatment method for waste incineration fly ash, a biological bacterial liquid containing bacillus subtilis and sphingomonas, a nutrient solution and the waste incineration fly ash are mixed for biological fermentation, and the two strains have the capabilities of efficiently degrading dioxin and solidifying heavy metals, and both meet the standard requirements; and the two strains have better alkali resistance, so that the two strains can be used for in-situ treatment of the waste incineration fly ash and the phosphatase cement to be compounded to obtain a lower-carbon environment-friendly calcination-free cement material. 本发明涉及微生物技术领域，具体涉及一种垃圾焚烧飞灰生物处理方法。本发明提供了一种垃圾焚烧飞灰生物处理方法，将含枯草芽孢杆菌和鞘氨醇单胞菌的生物菌液、营养液和垃圾焚烧飞灰混合，进行生物发酵，上述两种菌种具备高效的降解二噁英和固化重金属的能力，均达到标准要求，且两种菌种耐碱性更好使得其可以原位处理垃圾焚烧飞灰和磷酸酶水泥复配得到更加低碳环保免煅烧的水泥材料。
