Solid waste-based microbial composite curing material and application thereof in sludge curing
The invention belongs to the technical field of sludge treatment, and discloses a solid waste-based microbial composite curing material and application thereof in sludge curing. The composite curing material is prepared from the following raw materials in parts by mass: 0.2-0.4 part of a water treatment strain, 2-8 parts of soluble calcium salt, 5-10 parts of red mud, 7-16 parts of a flocculating agent and 15 parts of water. The composite curing material is applied to sludge curing, the sludge is rapidly dehydrated and cured through the synergistic effect of all the components, the water content of the sludge is remarkably reduced, pollutants such as nitrogen, phosphorus and heavy metal in the sludge are effectively controlled, and the cured sludge can be used as a building material; the effects of sludge reduction, stabilization, harmlessness and recycling are achieved, and meanwhile resource utilization of the industrial solid waste red mud is achieved.
本发明属于淤泥处理技术领域，公开了一种固废基微生物复合固化材料及其在淤泥固化中的应用。所述复合固化材料由以下质量份数的原料组成：水处理菌种0.2‑0.4份、可溶性钙盐2‑8份、赤泥5‑10份、絮凝剂7‑16份、水15份。将该复合固化材料应用于淤泥固化中，通过各组分的协同作用，使淤泥快速脱水固化，既显著降低了淤泥的含水率，又有效地控制了淤泥中氮、磷、重金属等污染物，固化后的淤泥能够用作建筑材料，达到了淤泥减量化、稳定化、无害化和资源化的效果，同时还实现了工业固废赤泥的资源化利用。
