The invention provides a water permeable brick based on graphene and solid wastes. The water permeable brick is prepared from municipal sludge, municipal waste soil, construction waste, coal ash, nonmetal tailings, graphene, bentonite, sodium silicate, pore forming substance and hydroxypropyl methyl cellulose. The water permeable brick with excellent performances is acquired in the manner of utilizing the construction waste, coal ash, graphene and nonmetal tailings as aggregates and utilizing the municipal sludge, municipal waste soil, bentonite and sodium silicate to bond the aggregate grainsand thus is endowed with the performances, such as, high strength, high temperature resistance and high wearing resistance. A large amount of municipal sludge, municipal waste soil and construction waste are effectively utilized and the recycling of the coal ash and the nonmetal tailing waste resources is realized, so that the environment protection is benefited, the industrial and regional economy and the development of urbanization are promoted.
