State and separated by partition wall three between the ecology pond systems area of center, system water inlet accesses the water distribution water channel, and the partition wall two is set
There is the downflow weir of water distribution water channel, the water outlet of water distribution water channel enters the middle wet land system area, the centre by overflow manner
Matrix is filled with wet land system area, the matrix includes from top to bottom being layered the planting soil layer of setting, ecological packing layer successively
With the pervious bed that catchments, the pervious bed that catchments is interior or lower section is provided with collector pipe, the collector pipe（Catchment section）Positioned at the centre
The bottom in wet land system area, the collector pipe are provided with the delivery port positioned at the center the ecology pond systems area, the center ecology
Pool system divides into phytal zone and profundal zone, and wherein profundal zone is located at the middle section in the center the ecology pond systems area, shallow water
Area is centered around the outside of the profundal zone, and the import of system outlet pipe is located in the profundal zone in the center the ecology pond systems area,
Intake successively after the tertiary treatment of water distribution water channel, middle wet land system area and central the ecology pond systems area, from system water outlet
Pipe is discharged.
The beneficial effects of the utility model are：By the scientific and reasonable combination of current wetland and pool system, ensure that wet
Ground strengthens nitrification, the denitrification of whole wet land system, strengthens phosphorous chemical combination to the high treatment capacity of polluted-water
The absorption of thing and precipitation, degradation of the microorganism to organic pollution is strengthened, ensure stable effluent quality, evaded water inlet
Concentration of suspension is higher and the shortcomings that block artificial swamp, so as to be adapted to the of a relatively high sewage of processing pollution level, it is allowed to
The fluctuation by a relatively large margin of influent quality and water, and there is Nitrogen/Phosphorus Removal, ensure that to total nitrogen, total phosphorus and SS, COD and
The clearance and level of purification of the pollutants such as BOD, reduce maintenance cost, extend the service life of system.

And/or pressure detecting instrument, the output access field control cabinet of the online temperature monitor/or pressure detecting instrument, pass through scene
The display of switch board is shown, in order to understand and judge the biochemical reaction situation inside pond body, for example, temperature is to influence
One important environmental factor of bacterial activity, and pressure then prompts in pond water-permeable and air permeable performance and thus biochemistry that may be present
Reaction problem, temperature/pressure can be detected according to needing to set related data processing circuit or device in field control cabinet
The output access relevant data processing circuit or device of instrument, handled with the display processing needed for carrying out with other, for example, at data
Reason circuit or device can be provided with warning output, in the temperature/pressure data fit alert if of detection, pass through warning output
The alarm lamp and/or alarm buzzer of connection are alarmed.
Foot bridge longitudinally and/or laterally can be provided with above the pond body, the both ends of the foot bridge are fixedly mounted
On pool wall or ground, thus, management and maintainer, which can be gone on bridge, closely to be checked and upkeep operation.
Whole system reasonably combines current wetland and pool systematic science, the water distribution water channel that current pass through outermost（It is good
Oxygen nitration reaction）, middle wet land system area（Anaerobic denitrifying reacts）, middle the ecology pond systems-phytal zone（Aerobic nitrification is anti-
Should）With middle the ecology pond systems-profundal zone（Anaerobic denitrifying reacts）, the alternating of Aerobic-anaerobic environment, which is changed, promotes micro- life
Removal of the thing to nitrogen-containing compound, while using the absorption of ecological filler reinforcement phosphorus-containing compound, reaction, enrichment, precipitation, it is maximum
Change and ensure that stable water outlet is up to standard.
Disclosed in the utility model it is each preferably with optional technological means, unless otherwise indicated and a preferred or optional skill
Art means are outside the further restriction of another technological means, can form some different technical schemes in any combination.
