The invention discloses a kind of urban rainwater reflow method, comprise the following steps：First, wetland is built at the edge in city, rainwater diversion pipe is built in city, filtering settling pond is built before wetland, rainwater diversion pipe is connected to filtering settling pond, filtering settling pond connection wetland；2nd, some parks are built in city, large area soil is retained in park, planted and plant trees and solid soil grass；3rd, building drainpipe is accessed into rainwater diversion pipe, catchment tray is set at the foot of the hill, catchment tray is accessed into rainwater diversion pipe, water leg, water leg connection rainwater diversion pipe are set on urban pavement.Rainwater in city is concentrated feeding filtering settling pond natural filtration by the present invention by rainwater diversion pipe, is ultimately delivered to wetland, and rainwater obtains natural filtration treatment, and then Natural Circulation, benefits urban environment in the circulating cycle；Due to creating a return flow line to urban rainwater, allow its natural back flow, recover its should by channel, allow urban construction reform of nature environment.
Description
Technical field
The present invention relates to a kind of urban rainwater reflow method, belong to technical field of resource recovery.
Background technology
For the treatment of rainwater, existing city is nearly all nature excretion, and excretion produces urban waterlogging when not falling.And drain
It is also that rainwater is directly discharged by sewer pipe, because rainwater is mingled with substantial amounts of pollutant, local water system is produced dirty
Dye.Urban water at this stage is mainly derived from river or underground water, the asphalt road or cement pavement of urban construction and draining
Pipe network, rainwater cannot be permeated, and underground water is progressively exhausted, and river is easily contaminated, a critically important original of these problems
Because being that, caused by existing city does not account for how processing rainwater.
The content of the invention
It is an object of the invention to solve problem present in current techniques, there is provided a kind of urban rainwater reflow treatment side
Method.
To reach above-mentioned purpose, the technology used in the present invention means are：A kind of urban rainwater reflow method, including
Following steps：
First, wetland is built at the edge in city, rainwater diversion pipe is built in city, filtering settling pond, rain are built before wetland
Water mozzle is connected to filtering settling pond, filtering settling pond connection wetland；
2nd, some parks are built in city, large area soil is retained in park, planted and plant trees and solid soil grass；
3rd, building drainpipe is accessed into rainwater diversion pipe, catchment tray is set at the foot of the hill, catchment tray is accessed into rainwater diversion pipe,
Water leg, water leg connection rainwater diversion pipe are set on urban pavement.
Further, in the step one, filtering settling pond is soil property pond, and pond body is using multiple square subpools or circular son
Pond, is connected between subpool by guiding gutter, and screen pack is set on the subpool being connected with rainwater diversion pipe, is set in guiding gutter entrance
Put screen pack.
Further, the surrounding of the filtering settling pond is planted trees and solid soil grass.
Further, in the step one, rainwater diversion pipe must not be connected with sewage conduct.
Further, in the step 2, park is built in city, and every 5 square kilometres of at least one, area is not less than
4000 square metres.
Further, in the step one, 8% of Wetland Area not less than urban size.
The beneficial effects of the present invention are：By rainwater diversion pipe, mountain region, building, rainwater on road surface in city are concentrated, sent
Enter filtering settling pond, filtering settling pond uses natural filtration, be ultimately delivered to wetland, rainwater is obtained at natural filtration in the circulating cycle
Reason a, part permeates the ground, and is partly into wetland, and then Natural Circulation, benefits urban environment；Due to being created to urban rainwater
One return flow line, allows its natural back flow, recover its should by channel, allow urban construction reform of nature environment.
Specific embodiment
With reference to embodiment, the present invention is further elaborated.
Embodiment 1
A kind of urban rainwater reflow method, comprises the following steps：
First, wetland is built at the edge in city, rainwater diversion pipe is built in city, filtering settling pond, rain are built before wetland
Water mozzle is connected to filtering settling pond, filtering settling pond connection wetland；
2nd, some parks are built in city, large area soil is retained in park, planted and plant trees and solid soil grass；
3rd, building drainpipe is accessed into rainwater diversion pipe, catchment tray is set at the foot of the hill, catchment tray is accessed into rainwater diversion pipe,
Water leg, water leg connection rainwater diversion pipe are set on urban pavement.
Embodiment 2
Used as the further optimization of embodiment 1, in the step one, filtering settling pond is soil property pond, and pond body uses multiple side
Shape subpool or circular subpool, are connected between subpool by guiding gutter, and screen pack is set on the subpool being connected with rainwater diversion pipe,
In guiding gutter entrance, screen pack is set.
Filter screen is set on the subpool being connected with rainwater diversion pipe, in allowing water to flow into pond naturally, and debris were rested on
On filter screen, easy cleaning will not allow debris to be soaked in water rotten, polluted source again.
Meanwhile, planted trees and solid soil grass in the surrounding of the filtering settling pond.With grass, the solid soil of tree, can afforest again, improve ring
Border, forms Natural Circulation.
In the step one, rainwater diversion pipe must not be connected with sewage conduct.
Embodiment 3
Used as the further restriction to embodiment 2, in the step 2, park is built in city, and every 5 square kilometres at least
1, area is not less than 4000 square metres.So in city, just set at a certain distance natural rainwater-collecting with
Bleed back a little, be that rainwater backflow builds node while conditioning urban environment.
And urban size is directed to, and in the step one, 8% of Wetland Area not less than urban size.Wetland Area is less than this
During ratio, disposal ability will be unable to reach, due to by the way of Natural Circulation, needing to meet face for park and Wetland Area
Product requires to can be only achieved actual treatment effect.
The present invention is concentrated mountain region, building, rainwater on road surface in city by rainwater diversion pipe, sends into filtering settling pond, mistake
Filter sedimentation basin uses natural filtration, is ultimately delivered to wetland, and rainwater obtains natural filtration treatment in the circulating cycle, and a part penetrates into ground
Under, wetland, and then Natural Circulation are partly into, benefit urban environment；Due to creating a return flow line to urban rainwater,
Allow its natural back flow, recover its should by channel, allow urban construction reform of nature environment.
Application embodiment is only intended to illustrate technical characteristic disclosed in the present application that those skilled in the art are by simple
Carried out change is replaced, the scope that the application is protected is still fallen within.
