Collected water recycling system, method and device and storage medium

The embodiment of the invention discloses a collected water recycling system, method and device and a storage medium. The collected water recycling method comprises the following steps: acquiring environmental data and water body data in a water requiring sub-region acquired by a detection component; based on the environment data and the water body data, judging whether the water demand sub-region meets a preset irrigation condition or not; sending irrigation information to a controller in response to the condition that the water demand sub-region meets a preset irrigation condition, so that the controller generates an irrigation instruction based on the irrigation information to control the water taking part and the irrigation part to use water in the water storage part for irrigation. According to the present specification, based on the environmental data and the water body data in the water-requiring sub-region, whether the water-requiring sub-region meets the preset irrigation condition is determined, so
