This invention discloses a drawer-type ceramic membrane rainwater treatment device and method. The device includes an inlet pipe, a membrane tank, separation baskets, packing material, an outlet pipe, and a ceramic membrane. Multiple sets of parallel separation baskets are vertically arranged within the membrane tank. Each separation basket contains a ceramic membrane, and the outer side of the baskets is filled with packing material. The packing material creates an anoxic environment through stacking to enhance denitrification. The packing material and the ceramic membrane together form a packing-membrane composite zone within the membrane tank. The outlet of the inlet pipe is located above the packing material, and the outlet pipe is connected to the product water zone of the ceramic membrane. The treatment method involves rainwater entering the membrane tank through the inlet pipe, undergoing anoxic biological pretreatment for efficient nitrogen and phosphorus removal and pre-filtration, followed by deep filtration through the ceramic membrane, and then being discharged through the outlet pipe under gravity. This invention's treatment device features low energy consumption, outstanding denitrification effect, minimal membrane fouling, and easy disassembly and replacement of the ceramic membrane, making it suitable for urban rainwater purification and resource utilization.

This invention discloses a radiative cooling and cold storage device based on self-regulation of phase change volume change, belonging to the field of sky radiative cooling technology. It solves the problem that traditional direct-contact structures struggle to achieve controllable storage and efficient utilization of cooling capacity. The device includes a radiative cooling plate, a phase change cold storage unit, and an insulation layer. The phase change cold storage unit is located inside the insulation layer and below the radiative cooling plate. The phase change cold storage unit includes a sealed cavity and a phase change material filled within it. During the phase change process, as the volume of the phase change material changes, the sealed cavity adaptively adjusts its height, shifting towards the upper surface of the radiative cooling plate, thereby altering the contact state between the cavity and the plate. This invention achieves adjustment of radiative cooling capacity under different operating conditions by adaptively regulating contact thermal resistance through phase change volume change, thus improving cooling capacity utilization efficiency and mitigating the day-night cooling mismatch problem.
