Embodiment 1

[0037] In this embodiment, realize according to the following steps:

[0038] 1. The teaching building, dormitory building, and comprehensive building are equipped with roof greening systems, with a total area of ​​more than 20,000m 2 , including roof gardens and roof lawns. When it rains, the roof garden and the lawn directly use part of the rainwater, and a rainwater overflow system is installed at the same time, and the excess rainwater is overflowed and discharged.

[0039] 2. All roads, leisure squares, and outdoor parking lots on the campus are paved with permeable water, with a total area of ​​more than 10,000m 2 ;Green land area 55000 m 2 , the greening rate exceeds 40%; two rain gardens and one wetland cover a total area of ​​15,000 m 2 . During the rainfall process, the green space, rain garden, and wetland directly absorb part of the rainwater, that is, the rainwater is directly used.

[0040] 3. The rainwater collection system is "permeable infrastructure - st...

Abstract

The invention discloses a sponge type campus rain swage recycling method based on low impact development. By adopting effective entrapment way and late treatment facility, the campus space is reasonably utilized to improve the rainfall runoff volume control ability and provide a water gathering surface and a storage space; meanwhile, a sewage regeneration system is established by use of the underground space. The problem in draining rainwater in a campus can be solved, and a water source can be provided for the campus. The regeneration and reusing of rain sewage are realized while the drainage safety of the campus is ensured, thus the problems of water shortage and waterlogging in the campus are remarkably relieved, and overall ecological system of the campus can be recovered; through the self-cleaning ability of the natural ecological system, the ecological environment of the campus is improved, and a beautiful ecological campus is constructed. 80% or more of the annual rainfall and 85% or more of the annual sewage in the campus are recycled.

Description

technical field [0001] The invention relates to a method for recycling and reusing campus rainwater and sewage. Background technique [0002] With the rapid development of economy and urbanization, there is an extreme shortage of water in cities. On the other hand, waterlogging occurs frequently, and sewage flows across. The contradiction of water resources is extremely prominent. How to eliminate floods and recycle water resources in cities, realize the utilization of sewage resources, and collect and utilize rainwater has become one of the main issues. Low-impact development is an ecological technology system that can easily realize urban rainwater harvesting and utilization. The key lies in in-situ collection, natural purification, nearby utilization or replenishment of groundwater; its principle is to follow ecological priority and combine natural methods with artificial measures , optimize the utilization of rainwater resources and the protection of the ecological envi...
