It is convenient to set operational management, has both and afforests and beautifies environmental activity well.
To achieve the above object, the present invention adopts the following technical scheme that.
A kind of bioreactor of the present invention-plant gives birth to delay tank combined system, including water distributing trough, bioreactor,
Regulating reservoir plants raw delay tank.Water distributing trough, bioreactor, regulating reservoir, the raw delay tank of plant combine successively from front to back, water distributing trough
It is connect with bioreactor by pipeline, bioreactor water outlet is directly entered regulating reservoir, and it is stagnant that life is planted in the access of regulating reservoir overflow port
Stay slot.Sanitary wastewater is after collection, followed by above-mentioned apparatus, to obtain further purified treatment.
The front end of the water distributing trough is equipped with filter screen, for intercepting bulky grain inorganic matter.
The bioreactor bottom is equipped with sand filtration aeration head, and it is PVA-EM bacterium carriers that material is loaded in inside（With poly- second
Enol wraps up carrier granular made from EM bacterium）, EM bacterium are efficacious microbial colony, include mainly photosynthetic bacteria, lactic acid bacteria, yeast
The addition energy efficient hardening system of a variety of mushrooms such as bacterium, actinomyces and der Pilz, EM bacterium imitates the processing of nitrogen phosphorus, COD in sewage
Fruit improves the treatment effeciency of system.Sewage is from bioreactor（2）Bottom enter, under the action of Aeration fan with PVA-EM
Bacterium carrier comes into full contact with, and ensure that the heavy-duty service of system.
The structure of the raw delay tank of the plant is layer of plants, aquifer, coating, packing layer, sand filtration successively from top to bottom
Layer and gravel drainage blanket.It plants in raw delay tank packing layer and is used as sorptive material equipped with zeolite, cooperate with the work of plant and microorganism
With purification of water quality is achieved the effect that, especially to the treatment effect stability and high efficiency of phosphorus recycling.
The preferred canna of layer of plants of the present invention is as serike.
Highly preferred aquifer of the present invention is 15cm.
Coating of the present invention is bark, in fact it is highly preferred that is 5cm.
Bed stuffing height of the present invention is preferably 35cm, and wherein filler is red soil, compost and zeolite, and proportions are
35:10:55。
Highly preferred sand filter of the present invention is 15cm.
Gravel drainage blanket of the present invention is preferably highly 15cm.
The present invention has the following advantages.
The present invention may be implemented by using biological-ecological combination to organic matter, the nitrogen and phosphorus in country sewage
The target that salt efficiently removes, especially the treatment effect stability and high efficiency to the reluctant phosphorus recycling of common biosystem, this
Outside, which saves, maintenance management is convenient, operating cost is low；Simultaneity factor effluent quality is good, and can effectively beautify rural area
Environment.

Specific implementation mode
The present invention will be described further in conjunction with attached drawing.
Attached drawing 1 is that delay tank combined system is given birth in bioreactor of the present invention-plant, by water distributing trough 1, bioreactor
2, regulating reservoir 3 and plant raw delay tank 4 four big major part composition, 2 bottom of bioreactor is equipped with sand filtration aeration head 12.Sewage is logical
Piping 11 is discharged pond 3 after the adjustment and enters the raw delay tank 4 of plant from water distributing trough 1 into bioreactor 2, into plant life delay tank 4
Free bacterium can adhere on filler and root system of plant, continue degrade sewage in pollutant；The organic matter that wherein sewage contains,
