Process for preparing bio-bricks by recycling municipal domestic sludge incineration ash
The invention belongs to the technical field of sludge treatment, relates to a process for preparing bio-bricks by recycling municipal domestic sludge incineration ash, and aims to manufacture sludgeincineration ash into a novel building material which is ecological, environment-friendly, economical and efficient. According to the method, the municipal domestic sludge incineration ash is solidified into harmless biological bricks by utilizing a microorganism-induced calcium carbonate deposition technology, harmful heavy metal ion components in the waste incineration ash can be stably fixed, and harmlessness of the waste incineration ash is realized. According to the method, solid waste reduction treatment and resource utilization are combined, reduction, harmless and resourceful treatmentof the sludge incineration ash is achieved, and a novel building material with application value is obtained. The method is expected to be applied to the fields of buildings, capital construction andthe like and has better environmental protection benefits and economic benefits.
本发明涉及污泥处理技术领域，特别涉及一种城市生活污泥焚烧灰渣资源化制备生物砖的工艺，为将污泥焚烧灰渣制作成生态环保、经济高效的新型建筑材料，本发明利用微生物诱导碳酸钙沉积技术将城市生活污泥焚烧灰渣固化成无害化的生物砖，并能够稳定的固定垃圾焚烧灰渣中的有害重金属离子成分，实现垃圾焚烧灰渣的无害化；本发明将固体废弃物减量化处理与资源化利用相结合，既实现了污泥焚烧灰渣的减量化、无害化、资源化处理，又得到了一种具有应用价值的新型建筑材料，有望应用于建筑、基建等领域，具有更好的环保效益与经济效益。
