The invention belongs to the technical field of resource reuse, and particularly relates to a renewable unfired filter material and a preparation method, application and regeneration method thereof. The invention provides a filter material, which is mainly prepared from the following components: sal industrial solid waste, construction waste, sludges, alkali activators and foaming agent; the sal industrial solid waste is selected from one or more kinds of flyash, metakaolin, solid sulfur ash, coal gangue, cinder, slag, zeolite slag, red mud, waste gypsum, desulfurization ash, carbide slag andindustrial dust; the construction waste is selected from one or more kinds of waste concrete blocks, waste cement mortar, crushed stones, waste slag soil, waste bricks and waste tiles. According to the renewable unfired filter material and the preparation method, application and regeneration method thereof, the consumption of the construction waste, the sludge and the industrial solid waste is realized simultaneously, and the resource utilization of the construction waste, the sludge and the industrial solid waste is achieved, and great economic and social values are brought.
