Treatment method for sludge used for producing baking-free bricks
The invention belongs to the technical field of building materials, and relates to a treatment method for sludge used for producing baking-free bricks, maggots are put into sludge subjected to preliminary dehydration, a maggot recovery device is put on the surface of the sludge after treatment for a period of time, and the maggots climb into the maggot recovery device, so that most maggots are recovered; after the maggot recovery device is removed, high-temperature hot air blowing is adopted to dry the surface of the sludge, and maggots which are not collected on the surface of the sludge are killed and collected; and then the sludge in the biological treatment disc is discharged for next-step treatment. The sludge is treated through maggots, the content of organic matter in the sludge is further reduced, generation of harmful substances such as dioxin in the high-temperature drying link of the sludge can be reduced, meanwhile, the content of carbon particles in dried sludge powder can be reduced, and the strength and density of the baking-free brick can be improved; the collected live maggots and maggot corpses can be used as feed and the like, and certain economic benefits can be generated.
本发明属于建筑材料技术领域，涉及一种对于生产免烧砖所用污泥的处理方法，通过对经过初步脱水的污泥投放蛆虫，处理一段时间在污泥表面投放蛆虫回收装置，使蛆虫爬入蛆虫回收装置从而将大多数蛆虫回收；撤去蛆虫回收装置后采用高温热风吹扫使污泥表面干燥并杀死污泥表面未被收集的蛆虫并收集；随后将生物处理盘内的污泥排出，进行下一步处理。本发明通过蛆虫对污泥进行处理，进一步降低污泥中有机质的含量，有利于减少污泥在高温烘干环节中二噁英等有害物质的产生，同时也能降低烘干后污泥粉料中碳颗粒的含量，有助于提高免烧砖的强度和密度；收集的活蛆虫和蛆虫尸体可做饲料等用途，能产生一定的经济效益。
