Separate, top is connected, and granule filter material is filled between outer layer zone and internal layer area.
The ratio between the cross sectional area in the quick stream internal layer area and stream outer layer zone at a slow speed is 1: 2-5, quickly flows internal layer area stream
Speed, which is higher than, flows at a slow speed outer layer zone.
The water distribution area thickness is 5-20cm, and it is filled with cobblestones or rubble filtrate that grain size is 20-50mm, ensure
Water distribution is uniform.
The gathering ground thickness is 5-20cm, and it is filled with cobblestones or rubble filtrate that grain size is 20-50mm, ensure
It catchments uniformly.
The granule filter material filled between outer layer zone and internal layer area be grain size be 5-10mm lime stone, quartz sand,
Cobblestone or zeolite.
Kind is implanted with water plant on the granule filter material, water plant can be selected from reed, canna, thaliadeabata, cattail,
One or more of calamus, cyperus alternifolius.
The present invention become flow velocity polluted-water ecological purification system purification method be：Sewage is flowed by bottom water inlet pipe first
Internal layer area, water flow through after water distribution area homogenizing upwards vertical seepage flow by internal layer area quartz sand filter media to the area at the top of, and backward four
All spoke stream enters outer layer zone, and seepage flow enters gathering ground downward vertically, most afterwards through outlet pipe outflow system.
The beneficial effects of the invention are as follows：
By double-layer structure design method, simultaneously different infiltration coefficient fillers are filled, so that internal layer water velocity is higher than outer layer, has
Conducive to the plantation for intercepting inorganic particulate matter and combining hygrophyte is filtered in inlet area, by the particulate matter filtering in sewage, carbon
Cycle and the compact control of nitrogen cycle process realize the purpose of efficiently removal pollutant in the same ecological purification system,
There is with good investment, operational management conveniently to have both beautiful function, the place especially suitable for rural scattered domestic sewage simultaneously
Reason.

Specific implementation mode
Only it is below presently preferred embodiments of the present invention, is not intended to limit the present invention in any form.
As shown in Figure 1, a kind of change flow velocity polluted-water ecological purification system, equipped in water inlet pipe 1, water distribution area 2, quick stream
Outer layer zone 6, gathering ground 7 and outlet pipe 8 flow at a slow speed in floor area 3,
1 bore of water inlet pipe is 15mm, is connected to 2 bottom of water distribution area, and water distribution area 2 is located at quickly 3 bottom of stream internal layer area, high
Degree is 10cm；8 bore of outlet pipe is 15mm, is connected to 7 bottom of gathering ground, and gathering ground 7, which is located at, flows at a slow speed 6 bottom of outer layer zone,
Height is 10cm, and it is 20mm-50mm cobblestones that grain size is filled in water distribution area 2 and gathering ground 7；Quickly stream internal layer area 3, which is located at, flows at a slow speed
In outer layer zone 6, it is circular concentric quickly to flow internal layer area 3 and the cross section of stream outer layer zone at a slow speed（As shown in Figure 2）, wherein：Quickly
3 a diameter of 40cm of internal layer area is flowed, water (flow) direction is upward；6 a diameter of 80cm of outer layer zone is flowed at a slow speed, and water (flow) direction is downward, total to fill
Height is 90cm, and internal layer area 3 separates with 6 bottom of outer layer zone, and top is connected, and 5 are filled between outer layer zone 3 and internal layer area 6
The quartz sand of mm -8mm, the wherein packed height in internal layer area are 70cm, and the packed height of outer layer zone is 80cm, is planted on quartz sand
Plant canna.
Whole system is made of pvc pipe, dischargeable capacity 200L, hydraulic detention time 1d, day output 200L/d.
Purification method is：Sewage flows into internal layer area by bottom water inlet pipe first, and water flows through vertical upwards after water distribution area is homogenized
Seepage flow is by internal layer area quartz sand filter media at the top of the area, and then spoke stream enters outer layer zone around, and downward vertically seepage flow into
Enter gathering ground, most afterwards through outlet pipe outflow system.
When operation, since internal layer volume is smaller, flow velocity is larger, and the filtering for carrying out inorganic particulate matter first intercepts；In addition into
Water pollutant concentration is higher, and dissolved oxygen concentration is relatively low, and anaerobic reaction, work of the organic carbon in microorganism occurs in internal layer area bottom
With lower anaerobic digestion, during flow is upward, due to the oxygen of plant root exudation, dissolved oxygen concentration is continuously increased, to being
System surface layer, as nitrification zone, realize that the nitrification of organic nitrogen, subsequent flow enter outer layer zone and flow downward, and dissolved oxygen is reduced again,
Denitrification occurs and converts nitrate nitrogen to nitrogen, discharge system, while organic matter is able to using organic matter as carbon source
It further decreases, to realize effectively removing for pollutant.
