Water storage device and water storage method for collecting, storing and cyclically utilizing rainwater

Abstract

The invention relates to a water storage device and a water storage method for collecting, storing and cyclically utilizing rainwater. The water storage device comprises a filtering well and a water storage pool, wherein a rainwater collecting pipe of a building is connected with the filtering well; the filtering well is connected with the water storage pool through a pipeline; a plurality of permeation pipes are connected onto the water storage pool; the water storage pool is connected with a lifting pump; the water storage pool is buried under the ground; and the top of the water storage pool is lower than the average year underground water level. According to the water storage method, in a rainy day, the rainwater collected by the rainwater collecting pipe is gathered into the filtering well; filtered clean water is gathered into the water storage pool by the filtering well; underground water permeates into the permeation pipes, and is gathered into the water storage pool through the permeation pipes; in a sunny day, the underground water permeates into the permeation pipes, and is gathered into the water storage pool by the permeation pipes; and when the water needs to be used, the lifting pump is started for extracting the water in the water storage pool, and the water is conveyed to places requiring to use the water. The water storage device and the water storage method have the advantages that the water collecting modes are various; both the filtered rainwater and the permeating underground water can be collected; rainwater resources are sufficiently utilized; the rainwater discharge quantity is reduced; and the municipal pipe network stress is relieved.

Description

technical field [0001] The invention relates to a water storage device for a residential area and a building, in particular to a water storage device and a water storage method for collecting, storing and recycling rainwater that effectively utilizes rainwater resources and is beneficial to environmental protection. Background technique [0002] Today, with the increasing development of the environmental protection industry, how to improve and upgrade the traditional rainwater collection tanks according to different geographical and geological conditions and make full use of rainwater resources has reached an imperative stage. Most of the traditional rainwater reuse systems rely on the roof to collect rainwater and collect it. There are often situations where heavy rainfall cannot be completely collected and small rainfall is not enough. Rainwater resources are not fully utilized. At the same time, the rainwater collected by the roof is relatively dirty. The collection pipeli...

Problems solved by technology

[0003] The present invention mainly solves the technical problems that the original rainwater reuse system does not collect enough rainwater, and the rainwater collected from the roof is relatively dirty, the collection pipeline is complicated to lay, which causes troublesome water treatment in the later stage, and the actual utilization rate of rainwater is not high; it provides a A water storage device that collects, stores and recycles rainwater, which can fully collect rainwater resources, has simple pipeline laying, collects while filtering, simplifies later water treatment, and improves the utilization rate of rainwater

[0004] At the same time, the present invention solves the technical problem that the original rainwater reuse system often has the situation that the large rainfall cannot be completely collected and the water of the small rainfall is not enough; it provides a water storage method for collecting, storing and recycling rainwater. It can fully collect rainwater, collect groundwater through infiltration at ordinary times, and also collect part of the water that seeps back into the ground after sprinkler irrigation and greening, so as to realize water recycling
