The Non-Point Source Net Zero Magic Cube refers to a device with disconnection functionality, which standardizes, modularizes, and intensifies the design of bioretention facilities using prefabricated components. Through multifunctional modules, it controls elevation, infiltration rate, and drainage time, while enhancing filtration and purification, ecological aesthetics, and sedimentation effects, adapting to various environments and achieving controllable storage functions. Additionally, based on delayed regulation processes, it intensively utilizes the space of prefabricated functional modules to store runoff rainwater, releasing it slowly and evenly after rainfall—effectively preventing urban flooding by "not competing for drainage during rain and discharging orderly after rain." Through delayed filtration, sedimentation, and purification, it effectively controls runoff pollution and enables automatic pollutant removal. Standardized modules improve construction quality, shorten construction cycles, reduce environmental pollution, and increase comprehensive benefits, making it a green, environmentally friendly, economical, and low-carbon foundational stormwater management facility for sponge cities.
