Road building slag taking municipal sludge as raw material, preparation method and application thereof
The invention belongs to the technical field of municipal sludge treatment, and particularly discloses road building slag taking municipal sludge as a raw material, a preparation method and application thereof. According to the invention, microorganisms subjected to enrichment culture are added into municipal sludge, and active thalli in the sludge are completely replaced by the microorganisms through a biological extraction reaction; the extraction microorganisms are mainly autotrophic bacteria, the sludge is mainly heterotrophic bacteria, the oxidation and acidification effects of the flora are utilized to condition the sludge, and the water content is reduced to the sludge treatment requirement after mechanical dehydration; and the slag is prepared by means of drying, calcining and the like and is used as a road building material, so that an efficient and economic new way is opened up for reduction, harmlessness and resourceful treatment of the municipal sludge and development of cheap road building materials.
本发明属于城市污泥处理技术领域,具体公开了一种城市污泥为原料的筑路矿渣及其制备方法与应用。本发明向城市污泥中投加富集培养的微生物,通过生物浸提反应,微生物将完全替代污泥中的活性菌体。浸提微生物是以自养菌为主,而污泥中则以异养菌为主,利用该菌群的氧化和酸化作用调理污泥,经机械脱水后将含水率降至污泥处置要求。之后通过干化、煅烧等手段制成矿渣,用于筑路材料,为城市污泥减量化、无害化和资源化处理处置,及开发廉价筑路材料开辟了高效经济新途径。
