Description
Technical field
The present invention relates to rainwater-collecting treatment technology, be specifically related to a kind of Urban Parks rainwater collecting and treating system.
Background technology
Water is Source of life, is important natural resources and strategic resource. From since the dawn of human civilization, water is exactly the mankind and the requirement of ecosystem existence, plays vital effect in human social development course always. It is known that, along with expanding economy, the growth of population and improving constantly of people's material and cultural life, all over the world that the demand of water resource is also growing, shortage of water resources problem by the common concern of countries in the world, produces because of water resource to be that various contradiction is just more serious. The United Nations just points out in 1997 " thoroughly evaluating to World Freshwater Resources " is reported: " water shortage problem will seriously restrict 21 century economy and social development, and may result in the conflict between country. "
At present, in Urban Parks, the utilization of rainwater resource is also not affected by enough attention, and some Urban Parks are not provided with special rainwater utilization system. It is all directly Water in Rainwater Drainage is entered municipal drainage pipeline that a lot of Urban Parks treat the attitude of rainwater, not only wasting substantial amounts of rainwater resource, add pumping equipment construction cost in vain, but also increase the pressure of municipal drainage pipeline, there is serious flood hidden danger. Park often lacks comprehensive consideration when planning and designing, puts undue emphasis on landscape effect, ignores the combination of view and rainwater utilization, does not excavate the effective measures of rainwater utilization from park landscape element; In park, the substantially all still tap water of flushing supply, reclaimed water, pouring water etc., causes a large amount of high-quality water resource waste. A lot of Urban Rain amounts are big, remain at the situation of short water supply, a lot of Urban Underground water levels are affected by exhaustive exploitation and decline year by year, the development in city is constituted serious threat, Urban Parks is more blunt for the reaction of rainwater, the effective rainwater utilization strategy of the system that is formed without, is the main cause causing a large amount of rainwater resource to waste. Nowadays the technology of rainwater utilization has developed to obtain comparative maturity, have only to rational utilization, the use water of park inner most can be solved in Urban Parks completely by rainwater utilization, and realize ecological benefits, economic benefit and the social benefit that rainwater utilization brings.
Chinese patent CN104372850A discloses a kind of park rainwater collecting and treating system, including rainwater accumulation pond, water tower, it is connected with some irrigation canals and ditches around the opening in rainwater accumulation pond, the top in rainwater accumulation pond is provided with dmp filter cover, being provided with rain water filtering device bottom rainwater accumulation pond, being provided with further below of rainwater accumulation pond cushions clean pond, and the drain pipe on rain water filtering device connects with the clean pond of buffering, being connected by water main between the clean pond of buffering and water tower, described water main is provided with water pump;The centre of dmp filter cover raises up formation boss, and surrounding's formation annular filter groove of dmp filter cover, the opening of annular filter groove is provided with ring-shaped gate panel. Therefore, the present invention has can carry out layered filtration, process, collection to the rainwater in park, fresh-water-saving resource, reduces the beneficial effect of park use water cost.
Chinese patent CN104863083A discloses the method for the cohesion formula drainage in a kind of gardens, relate to a kind of Drainage Design method, it includes two big steps 1, when the planning of greenbelt in little residential region and park green land, as Central Green Spaces or existing landform carries out appropriate reconstruction is the physical features that relatively around absolute altitude is bigger to select the land used of physical features low lying areas and periphery thereof; 2, the periphery connection of Central Green Spaces or the turnpike road round community or park, this invention can utilize landform to transform, Garden Greenland is made to have drainage and recharge of groundwater function, reduce gardens when rainy draining to municipal drainage pressure, it is greatly improved the functional of city trees and shrubs and the feature of environmental protection, saves substantial amounts of water resource.
