Rainwater storage and regulation system suitable for open large plane

Abstract

The invention discloses a rainwater storage and regulation system suitable for an open large plane. The rainwater storage and regulation system comprises a rainwater sewage intercepting and basket hanging device (1), a rainwater pretreatment device (2), a rainwater treatment device (3), a rainwater regulation tank and a rainwater utilization device (12), wherein the rainwater sewage intercepting and basket hanging device (1), the rainwater pretreatment device (2), the rainwater treatment device (3), the rainwater regulation tank and the rainwater utilization device (12) are communicated in sequence; the rainwater regulation tank comprises impermeable membranes (7) which are arranged at the bottom and on an inner wall of the rainwater regulation tank, an arched rainwater regulation module (9) which is arranged at the bottom of the rainwater regulation tank and a permeable layer (8) which is arranged on the arched rainwater regulation module (9); rainwater which enters the rainwater regulation tank is stored in the arched rainwater regulation module (9) through the permeable layer (8) and a permeating hole (92). According to the rainwater storage and regulation system, no water accumulation and drainage safety of an open large plane site can be effectively guaranteed, the problem of waterlogging caused by disaster weather is solved, and the recycling of rainwater resources is realized.

Description

technical field [0001] The invention belongs to the technical field of rainwater storage and purification, and in particular relates to a rainwater storage and storage system suitable for open large planes. Background technique [0002] In recent years, with the rapid development of urbanization, the area of ​​urban green space has gradually decreased, and most of the green spaces, wetlands, ditches and other areas that originally had the function of water conservation have evolved into hardened ground. The drainage of the pipe network has caused frequent waterlogging disasters and serious runoff pollution; but after the heavy rain, it has fallen into the dilemma of dryness and water shortage, and the heat island effect is significant. [0003] Therefore, in order to deal with the prominent urban stormwater problems and strive to achieve the national strategic goals of ecological cities and ecological civilization construction, the state has put forward high standards and ne...

Problems solved by technology

[0004] At present, the drainage systems of large open-air public places in cities such as schools, hospitals, airports, and stadiums mainly have the following shortcomings: when it rains, the normal use of the open-air places will be affected due to the water on the ground; The surface runoff of the place has been greatly increased, and the flood discharge capacity of the municipal pipe network is far from sufficient, which is likely to cause a
