River course microbial cultivation device
Technical field
The present invention relates to river regulation equipment technical field, especially relate to a kind of river course microbial cultivation device.
Background technology
The pollution of river is one of problem of environmental pollution of society growing interest.Such as, to be discharged in river course as the domestic refuse in main exogenous pollution source and sanitary sewage, a large amount of organic waste and humic substance is caused all to be deposited on river bed, reduce oxygen in water concentration, add the anaerobic environment of bottom of river channel, a large amount of fermenting organic material rots, produce excessive sulfide and obnoxious flavour, fishes and shrimps are caused to disappear, and follow-up settling covers and makes bottom of river channel occur solid state, finally there is water quality deterioration, black smelly in nutritive salt enrichment, the havoc ecological balanced system in river course, makes river course lose self-purification function.The influence factor of river regulation is a lot of also very complicated, and the cycle of administering is long, difficulty is large, has had a strong impact on the healthy living of The Surroundings in Cities quality and resident, has also become the key subjects of domestic and international environment specialist's research.
Meanwhile, river water body especially also exists large amount of organic matter in black and odorous water, is mainly the 3 large classes such as dissolved organic matter, suspended organic matter and sedimentary organic material matter.Organic substance is elementary composition primarily of C, H, O, N, P, S etc., and its biological chemistry composition is extremely complicated.Afore-mentioned characteristics is that biologic treating technique provides the foundation, and abundant organic matter is that the physiological activity of microorganism provides nutrition source.That is, if adopt microbial technique to administer river course, then there is very solid application foundation and wide development space.In fact, microbial technique not only may be used for water body purification, also can be used for wawter bloom and controls.
But the microorganism at present for administering river course comparatively disperses in river course, and growth result is not good, be difficult to the needs meeting river regulation.
Summary of the invention
The object of this invention is to provide a kind of river course microbial cultivation device, it has can effective accelerate growth of microorganism, thus can provide the feature on better basis for microbial treatment river course.
The technical solution adopted in the present invention is: river course microbial cultivation device, and described river course microbial cultivation device comprises:
---the framework formed after adopting rigid material to connect;
---biological filtering membrane, the seamed edge that the avris of this biological filtering membrane is fixed on those frameworks forms the cell body of a upper opening;
---multiple ball float, those ball floats are fixed in the upper lateral edges of this framework;
---multiple microbe carrier, those microbe carriers are placed or are fixed in the cell body of this biological filtering membrane formation;
---at least 1 aeration tube, the cell body bottom that this aeration tube is formed from this biological filtering membrane is passed, and this aeration tube be positioned at this cell body part on have breather hole.
The present invention is advantageously: can effective accelerate growth of microorganism, for microbial treatment river course provides better basis.The cell body that biological filtering membrane is formed is suspended in the top in river course by river course of the present invention microbial cultivation device by ball float, and microbe carrier is positioned at this cell body, thus microorganism has the microenvironment relative to river preferably water quality, organic substance can be absorbed grow preferably, finally can administer the pollution of river preferably.Meanwhile, aeration tube can increase enough oxygen for microorganism, meets the needs of microorganism growth further.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the perspective view of embodiments of the invention.
In figure:
10, framework;
20, biological filtering membrane;
30, ball float;
40, microbe carrier;
50, aeration tube.
Embodiment
Embodiment, as shown in Figure 1: river course microbial cultivation device, comprising: the parts such as framework 10, biological filtering membrane 20, multiple ball float 30, multiple microbe carrier 40, at least 1 aeration tube 50.Wherein:
This framework 10 is formed after adopting the rigid materials such as steel wire to connect, and it can be cylindrical.Preferably, this framework 10 is in square or rectangular parallelepiped, thus those rigid materials become 12 ribs of this framework 10.
The seamed edge that the avris of this biological filtering membrane 20 is fixed on those frameworks 10 forms the cell body of a upper opening.That is, this biological filtering membrane 20 is opened by the seamed edge of this framework 10.Wherein, this biological filtering membrane 20 can be tackled the suspended matter in river sewage, and can suspended particle in sieving secondary treated wastewater, and can the dissolved organic matter matter such as Eutrophication materials such as nitrogen, phosphorus in oxygenolysis secondary water, and have certain nitrification.
Those ball floats 30 are fixed in the upper lateral edges of this framework 10, thus aforementioned cell body can be made to be suspended in the top of river sewage.
Those microbe carriers 40 are placed or are fixed in the cell body of this biological filtering membrane 20 formation.
The cell body bottom that this aeration tube 50 is formed from this biological filtering membrane 20 is passed, and this aeration tube 50 be positioned at this cell body part on have breather hole (not shown on figure).Certainly, this aeration tube 50 needs to be communicated with oxygen or air source of the gas.
Like this, this river course microbial cultivation device is suspended in the top in river course, and microbe carrier is positioned at this cell body, thus microorganism has the microenvironment of better water quality, can grow preferably, finally can administer the pollution of river preferably.Meanwhile, aeration tube can increase enough oxygen for microorganism, meets the needs of microorganism growth further.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification sheets of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
