Sewage sludge shale ceramic particle and preparation method thereof

Sewage sludge shale ceramsite and a preparation method thereof are provided, which relates to the light energy-saving ceramsite of building materials and a preparation method thereof. The ceramsite of the invention consists of sewage sludge, shale and admixtures; the method of the invention uses the sewage sludge, the shale and the admixtures as raw materials; first, the shale is grinded into shale powder and then the sewage sludge, the shale and the admixtures are mixed and wedged to be granulated into round particles and then enter into a kiln; the products are obtained after going through drying, preheating, barking and being taken out of the kiln for cooling. The ceramsite employs the sewage sludge discharged directly from sewage treatment plants and the shale as major materials, which greatly saves land resource and partial shale mine resource and provides an extremely good way for the non-hazardous and reclaiming treatment of sewage sludge; the method of the invention is simple, energy-saving and resources-saving and the density rank of the ceramsite is 300-700. The ceramsite of the invention can be widely applied in lightweight aggregate bricks, lightweight aggregate sheet materials, lightweight aggregate concrete, etc. and can also be taken as the filter material of sewage treatment, the water-retaining agent in cultivation, etc.
