Detailed description of the invention
Fig. 1 is the city planning model schematic diagram of weir pool type sponge community in urban areas of the invention.
Specific embodiment
Below according to specific embodiments of the present invention, the present invention will be described in detail.
(1) weir pool type sponge new city model system
The new city sponge City Spatial System of this model construction, including " core ", " unit ", " gallery ", " node " four are wanted greatly Element.
(2) weir pool type sponge core
As new city region charge for remittance center, certain agriculture weir pool skin texture should be retained, repair weir pool wetland, be laid out multistage purification weir Pool system, the ecological sponge core for forming water conservation, infiltration, water transfer, water purification.Multistage purification weir pool system can enter big in rain flood Before type water body, using the existing agricultural breeding weir pool, transform the lotus root pool of regional connectivity as, mix the pool, marsh organism, weir pool plant etc. Purification pond system.
(3) weir pool type drains neighbourhood unit
With the division of 500m service radius, pass through the controllable rainwater volume of measuring and calculating all kinds of underlying surfaces of unit and neighbourhood unit annual flow Total amount target control volume, obtaining its difference is the volume for needing increased weir pool sponge facility, for following table.
Certain city sponge urban construction target is that annual flow overall control reaches 85%, and the rainfall of corresponding control 43.3mm The not direct outlet of thickness, greenery patches, one residential, annual flow overall control rate target corresponding to road/square be respectively 85%, 70% and 70%, index measuring and calculating is carried out by unit of the community 800m*800m, neighbourhood unit also needs to increase the volume of regulating and storing of 5667m3, The target that can be only achieved community's annual flow overall control rate 85% needs to arrange about 28 rainwater weirs pool (by 200 ㎡, 0.5 meter of tune It stores depth to calculate).
The draining of community, the pool, weir seeps stagnant pergola-community Yan Tang by plot Rain Garden-community and regulates and stores park-municipal drainage Rivers and canals level Four is constituted.Plot Rain Garden can store rainwater only, and one residential is made to can control target rainfall thickness;Extra rainwater flows through Stagnant pergola is seeped in community, and transmission is pooled to the park of regulating and storing community Yan Tang and carries out rainwater comprehensive utilization;Exceeded rainwater is discharged into city row In water rivers and canals.
(4) city weir pool sponge gallery
The big drainage system in the weir pool is built by urban transportation gallery, ecological green land gallery, to resist the sudden and violent of waterlogging prevention and treatment standard Rain is drained in 24 hours.By calculating under waterlogging prevention target, the water of regulating and storing of all kinds of land used pipe networks in city, community's sponge facility Amount, pumping plant drain flooded fields water, the water that city weir pool sponge gallery need to regulate and store can be calculated, further according to urban transport artery, green Ground layout, decomposes the volume that all kinds of gallerys are deployed.Wherein, regional ecological green land gallery should be averaged perpendicular lower than urban construction To, in favor of the discharge of rainwater be connected to.
(5) rural sponge weir pool node
Usually drainage facility is not all mating complete up and down in the rural area of new city periphery, and agricultural non-point source pollution is after the rain to the water environment in city There is secondary pollution again, therefore combines the weir pool in rural area, the sponge city self-loopa node for forming purification, regulating and storing.
On the one hand, the farmland of status and Yan Tang can be attached, is transformed into the weir pool wetland with cultivation purification function, It is formed " wetland-pool-sub-irrigation integrated water management system ".The system can be reduced the discharge of farmland pollution substance, improves and irrigates Fraction, efficiency of water application and grain yield.The increase of Wetland Area enriches two packing spaces in farmland ecosystem simultaneously Property, be conducive to the protection and reparation of farmland ecosystem.For example, by the agricultural drain in farmland through the lotus weir pool (precipitating, removal Grain object), the wild rice stem weir pool (nitrogen is converted to nitrate nitrogen, easy for plant to absorpt), the convexutricle sedge herb weir pool (absorbing ammonia, phosphorus), the water lily weir pool (anaerobic environment is conducive to organic matter and decomposes), fish pond Yan Tang (water storage adjusting), farmland is back to eventually by sub-irrigation.
On the other hand, using the group technology stream of " grille well+conditioning tank+pretreatment system+artificial swamp+ecological pond " Journey forms the self-circulating system of rural rain sewage+sponge wetland.After the sanitary sewage in rural area passes through septic tank preliminary treatment, lead to Sewage network is crossed through grid pond (removing big suspended matter, floating material), conditioning tank (homogeneous average), pretreatment system (carbon hydrate Object is degraded to fatty acid, solid matter is degraded to dissolved matter, larger molecular organics are decomposed into small organic molecule, is convenient for Oxygen reaction and plant absorption), artificial swamp (cyperus alternifolius, canna, iris etc. reduce ammonia nitrogen in sewage content), ecological pond it is (logical It crosses food chain and completes material transport, conversion and the transmitting step by step of energy, conversion, plantation water spinach, Chinese celery, lotus rhizome etc. play ecology warp The multi-purpose value of Ji wetland).
