Residual sludge resource utilization method
The invention relates to the technical field of sludge resource utilization, in particular to a residual sludge resource utilization method which is characterized by comprising the following steps: mixing, dehydrating, granulating, screening, calcining and utilizing. The method has the beneficial effects that (1) the sludge finished product obtained by treating the excess sludge is used for laying a guide and drainage layer and a blind ditch of a landfill, replacing a large amount of gravels, pebbles or macadam and replacing a large amount of clay, so that reduction, stabilization and harmlessness of the excess sludge are realized, resource utilization is realized, and the cost is reduced; the method has good economic benefits, and opens up a new way for sustainable development of the excess sludge. (2) the process is simple and practical, waste such as common industrial solid waste, construction waste, waste mountain soil and river sludge can be treated while the excess sludge is treated, the raw material components are flexible, the possible secondary pollution problem is reduced, the environmental protection pressure is greatly reduced, and good environmental benefits are achieved.
本发明涉及污泥资源化利用技术领域，尤其涉及一种剩余污泥资源化利用方法，其特征在于，包括混合、脱水、造粒、筛选、煅烧、利用。本发明的有益效果是：1)本发明利用剩余污泥经处理后获得的污泥成品，用于填埋场的导排层、盲沟铺设，代替砾石、卵石或碎石的大量使用，代替黏土的大量使用，不仅实现了剩余污泥的减量化、稳定化和无害化，而且实现了资源化利用，具有很好的经济效益，为剩余污泥的可持续发展开辟一条新的道路。2)本发明工艺简单实用，在处理剩余污泥的同时，也可以处理一般工业固体废物、建筑垃圾、废弃山土、河道淤泥等废弃物，原料成分灵活，减少了可能造成的二次污染问题，大幅减少环保压力，具有很好的环境效益。
