With the development of economy and the promotion of the three old reconstruction, the quantity of waste red brick is increasing. Improper disposal and application of waste red brick constitute a potential hazard of environmental pollution. The waste red brick has large specific surface area and porosity, which can absorb and filter sewage. In the experiment, the specific gravity and adsorption capacity of red brick sand and the adsorption effect of red brick sand on rhodamine B and methyl blue were investigated. The results show that the particle size of 10 mm is suitable for the red brick sand. The adsorption time was 4 h, the adsorption capacity of red brick sand reached 0.388 mL/g. The particle size of red brick sand was 30 mm, the dosage was 30.019 g/100 mL of water sample, and the decolorization rate of water sample reached 80.09%. It can be seen that red brick sand has good adsorption performance.
