The invention provides an ammonia nitrogen remover based on natural minerals and a preparation method of the ammonia nitrogen remover. The ammonia nitrogen remover is prepared from the following raw materials: orthorhombic zeolite, refined hillstone, clay minerals, inorganic salt compounds, magnesium oxide, siliceous sedimentary rock and modified inorganic filler. Through the specific inorganic salt compound and the siliceous sedimentary rock, a flocculating constituent formed by the prepared ammonia nitrogen remover in wastewater can be larger and more stable and cannot be dispersed and dissolved in water, and in addition, the added siliceous sedimentary rock has specific porosity and large specific surface area, so that the ammonia nitrogen remover can be used for removing ammonia nitrogen in wastewater. The polyaluminum sulfate can adsorb substances such as metal ions, microorganisms and bacteria in wastewater and generate synergistic adsorption with natural minerals added in the system, so that the ammoni
