Technical field
The utility model belongs to field of environment protection, is related to a kind of sewage disposal system, more particularly to a kind of opel oxygen
Change ditch and the sewage disposal system of biological floating bed combination.
Background technology
In recent years, body eutrophication was on the rise, and the requirement to water outlet nitrogen and phosphorus content improves constantly.According to《Cities and towns
Wastewater Treatment discharge standard GB8978-2002》, total nitrogen one-level A standards are 15mg/l, and one-level B is 20mg/l, total phosphorus
One-level A standards are 0.5mg/l, and one-level B is 1mg/l.Water pollution is more serious, and the improvement to polluted-water is extremely urgent.
In the prior art, conventional to have traditional type oxidation ditch, it is a kind of end to end recycle stream aeration irrigation canals and ditches, again
Claim circulated aeration tank.Oxidation ditch has the advantages that longer hydraulic detention time, relatively low organic loading and longer sludge age.
But it also has some shortcomings, when the carbohydrate in waste water is more, N, P content are uneven, and pH value is relatively low, sludge in oxidation ditch
Load is too high, dissolves hypoxgia, and spoil disposal, which does not wait freely, easily triggers the sludge bulking of der Pilz property；Nonaqueous reaction sludge bulking is mainly sent out
When raw relatively low in waste water water temperature and sludge loading is higher, when the load of microorganism is high, bacterium has drawn a large number of nutrients, due to
Temperature is low, and accretion rate is slower, and repertory plays the polysaccharose substance of a large amount of high viscosities, the surface attachment water of activated sludge is increased greatly
Add, SVI values are very high, form sludge bulking.Also have using biological floating bed carry out sewage disposal, as Chinese invention patent application discloses
" stereo ecological floatation bed and its process for purifying water ", the device can significantly improve water correction effect, particularly difficult degradation and pollute
The clean-up effect of thing.And floating bed water inlet use water spray system, it is not necessary to separately plus aeration oxygen replenishing device, can just be provided for aquatic animal
Good habitat.But it carries out water body denitrification only with biological floating bed method and strengthens reparation, for the relatively low dirt of BOD concentration
Water can not be handled well.
Therefore, the sewage disposal system for studying a kind of opel oxidation ditch and biological floating bed combination is very valuable.

In order to solve the above technical problems, technical scheme is as follows used by the utility model：
A kind of sewage disposal system of opel oxidation ditch and biological floating bed combination, including with sewage import and export by three
The opel oxidation ditch of individual concentric circles raceway groove composition and biological floating bed pond, after the sewage of pretreatment is handled in opel oxidation ditch
Flow into biological floating bed pond and further purify, it is biological floating bed connected by linking up with floating bed pond, at least 2 floating beds are sequentially connected,
Described is biological floating bed including filler, plant and planting frame.
Preferably, described opel oxidation ditch will be aerated and precipitation is integrated in one.
Preferably, described biological floating bed pond body is cylinder, bottom of pond is cone, has inlet channel and discharge pipeline,
Acted on using gravitational settling and remove sludge.
Preferably, it is equipped with valve on the pipeline.
Preferably, described floating bed bed body material selection molding environment-protecting polythene material, the material of planting frame is polyphenyl
Ethene.
Can be activated carbon, haydite or spherical suspending filling material as preferred, described filler.
As preferred, the water plant planted is emergent aquactic plant Chinese celery, calamus and water spinach etc..
As preferred, the density for the emergent aquactic plant planted is 18 plants/m2。
As a result of above-mentioned technical scheme, compared with prior art, acquired technological progress exists the utility model
In the utility model using opel oxidation ditch and the sewage disposal system of biological floating bed combination, not only can farthest save
About land resource, additionally it is possible to improve the treatment effect of sewage.Wherein opel oxidation ditch collection aeration and sedimentation and one.Sewage first flows
Through opel oxidation ditch, during the synchronous nitration and denitrification in opel oxidation ditch such as COD, BOD, TN, TP therein just
Step, which absorbs, to be removed, and by aeration, adds the dissolved oxygen content in water body.It is biological floating bed to utilize aquatic macrophyte in growth course
In the characteristics of elements such as nitrogen, phosphorus being absorbed, and the root system of plant has huge specific surface area, can be in water body
Microorganism preferable absorption carrier is provided, form biofilm carrier, can be good at inhaling the suspended material in water body
It is attached, and root system of plant can also be enriched with a series of heavy metal element and organic pollution in water body, finally be given birth in plant
After long maturation, plant is moved away from into water body, the pollutant in water body is greatly reduced, water quality is improved, so as to be aquatic
Ecological environmental condition is created in existence, the procreation of biology, and possibility is provided to repair aquatic ecosystem.
Sewage disposal system whole process does not add any chemical agent used by the utility model, utilizes physical absorption and life
Thing acts on the purification of city domestic sewage.And the system is easy to maintain, the selection of integral material has diversity.Ring can be selected
Protect polythene material, convenient material drawing；Entirety is easy to dismounting and harmony is preferable；The selection of water purification filter material layer therein also allows for taking
Material, it is easier to large-scale promotion.
The utility model is applied to sewage disposal of the municipal sewage before river course is discharged into.
The utility model is described in further detail below in conjunction with Figure of description and specific embodiment.
