A sponge city rainwater recycling device

Abstract

The invention relates to the technical field of rainwater regeneration devices, and discloses a sponge city rainwater regeneration utilization device, comprising a vegetation layer, the lower layer of the vegetation layer is provided with a side brick layer, and the lower layer of the side brick layer is provided with a mixed carbon slag layer , one side of the vegetation layer is provided with a drainage channel, the top of the drainage channel is movably equipped with a well plate, and the middle part of the drainage channel is movably equipped with a grid plate, and the mixed carbon slag layer and the bottom of the drainage channel are both A water collecting layer is provided, a filter screen layer is arranged above the water collecting layer, and a protective screen is fixedly installed above the filter screen layer. In the present invention, by setting a water collection tank inside the water collection layer, combined with the use of water purification pipes, buffer plates and sewage pipes, the rainwater can be divided into the bottom sewage and the upper clean water before the system is purified, thereby reducing the purification required for subsequent rainwater The steps reduce the workload of rainwater regeneration, thereby improving the efficiency of rainwater purification and improving the rationality and feasibility of the device.

Description

technical field [0001] The invention relates to the technical field of rainwater regeneration devices, in particular to a rainwater regeneration and utilization device for sponge cities. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water. Utilization, the construction of sponge cities should follow the principles of ecological priority, combine natural methods with artificial measures, and ensure the safety of urban drainage and waterlogging, maximize the accumulation, infiltration and purification of rainwater in urban areas, and promote rainwater resources. In the process of sponge city construction, the systemic nature of natural precipitation, surface water and groundwater should be coordinated, water supply, drainage and other water recycling links should be coordinated, a...
