Method for treating organic matters in municipal sludge for producing baking-free bricks
The invention belongs to the technical field of buildings, and relates to a method for treating organic matters in municipal sludge used for producing baking-free bricks, earthworms are put into the sludge subjected to preliminary dehydration, an earthworm recovery device is put on the surface of the sludge after treatment for a period of time, and the earthworms climb into the earthworm recovery device, so that most earthworms are recovered; removing the earthworm recovery device, and blowing by high-temperature hot air to dry the surface of the sludge, kill the earthworms which are not collected on the surface of the sludge and collect the earthworms. According to the method, the sludge is treated through the earthworms, organic matters in the sludge are further absorbed or decomposed, the content of the organic matters in the sludge is reduced, generation of harmful gases in a high-temperature drying link of the sludge is reduced, and meanwhile, the content and the particle size of carbon particles in dried sludge powder can be reduced; the strength and the density of the baking-free brick are favorably improved.
本发明属于建筑技术领域，涉及一种生产免烧砖所用市政污泥中有机质的处理方法，通过对经过初步脱水的污泥投放蚯蚓，处理一段时间在污泥表面投放蚯蚓回收装置，使蚯蚓爬入蚯蚓回收装置从而将大多数蚯蚓回收；撤去蚯蚓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蚯蚓并收集。本发明通过蚯蚓对污泥进行处理，将污泥中的有机质进一步进一步吸收或分解，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有害气体的产生，同时也能降低烘干后污泥粉料中碳颗粒的含量和粒径，有助于提高免烧砖的强度和密度。
