[0002] Rainwater recycling is a sustainable way to utilize rainwater resources. It can reduce the demand for groundwater and tap water, alleviate the burden on urban drainage systems, and contribute to environmental protection. Rainwater treatment equipment is a key component of rainwater recycling. It can collect, pre-treat, biologically treat, and then treat rainwater through advanced treatment, thereby achieving the goal of recycling rainwater and realizing sustainable water resource utilization.

[0003] When collecting rainwater, existing rainwater collection pools generally install a filter at the upper opening of the collection pool to filter large solid impurities such as leaves.
