In recent years, rainwater storage and infiltration technology has gradually attracted attention. These technologies not only effectively alleviate urban waterlogging problems, but also promote the sustainable use of water resources. However, existing rainwater storage technologies often have complex structures, high construction difficulty, and high maintenance costs, which limit their widespread application. In addition, the efficiency and stability of infiltration technology also need to be improved to meet the needs of different environmental conditions. At present, common rainwater storage technologies include underground water storage tanks, surface storage tanks, and green roofs. Underground water storage tanks have a large water storage capacity, but the construction cost is high and a large amount of underground space is occupied. Surface storage tanks are relatively simple to construct, but are easily affected by external environments and have low water storage efficiency. Green roofs have good ecological benefits, but their water storage capacity is limited and the maintenance cost is high. In terms of infiltration technology, common methods include sand filtration, activated carbon filtration, and biological filter tanks. Sand filtration has low cost but limited efficiency. Activated carbon filtration has good effects but high cost. Biological filter tanks have good ecological benefits, but their stability and treatment efficiency are greatly affected by environmental factors.
