Description
Technical field
The present invention relates to biofilm reactor packing technique field, more particularly to suspension built in a kind of biofilm reactor
Filler.
Background technology
Biofilm is born at the end of the 19th century, due to the characteristics of its biomass is high, and operating cost is low, is applied at sewage
In the practical application of reason, but since filler dehydration is easily hardened, the characteristics of biomembrane is easy to fall off, biofilm is difficult, reality
With being somewhat limited.Therefore, it is necessary to a kind of new fillers to solve biofilm reactor difficulty biofilm, biomembrane
Caducous problem.
The content of the invention
The present invention provides floating stuffing built in a kind of biofilm reactor aiming at above-mentioned defect.This filler
With large specific surface area, good hydrophilic property, bioactivity is high, and extension mould is fast, and high treating effect, impact resistance is good, and service life is long
The characteristics of.
Floating stuffing technical solution built in a kind of biofilm reactor of the present invention is that filler uses high density polyethylene (HDPE)
(HDPE) material, material surface are embedded with Powdered Activated Carbon, iron powder, starch, potassium dihydrogen phosphate, ammonium carbonate, manganese iron axinite powder
The solid granule of composition, so that microorganism can quickly adhere to simultaneously growth and breeding on these nutrition points.
The iron and manganese oxides of the present invention are purchased from Shanghai Venus chemical engineering industry Co., Ltd.
0.95 ± 0.2g/cm of packing density3, it is ensured that it is at suspended state in water.
Floating stuffing built in a kind of biofilm reactor includes the following component of percentage by weight：
The filler includes the blade that multilayer is in tower-like arrangement, and every layer of blade is 2-10 pieces, and the bottom of every layer of blade is in
The heart is gathered, and vane tip radially distributes obliquely, and adjacent two layers blade is in be spaced apart.Filler maximum gauge is 45mm,
Width of blade is that the distance between 4-7mm, levels blade is 2-5mm, and every blade back has one directly by bottom to top
Footpath is the vertical bars of 0.5mm.
High temperature using 180 DEG C -230 DEG C melts high density polyethylene (HDPE), by active carbon powder, iron powder, starch, carbonic acid
Ammonium, potassium dihydrogen phosphate, iron and manganese oxides powder are added in the high density polyethylene (HDPE) of molten state, are then fixed filler by being molded
Shaping.
Filler is placed in the sewage treatment structure containing activated sludge, the microorganism in water quickly lives with filler surface
Property basic point is combined, and is firmly attached to filler surface, and fast-growth breeds to form biomembrane.The filler of biomembrane is attached with,
It in the case of aeration or stirring, rotates freely, fills the matrix such as the organic matter in microorganism and water in biomembrane, ammonia nitrogen
Tap is touched, and is adsorbed and is carried out metabolic breakdown.In addition, filler has a substantial amounts of cavity, microorganism growth and breeding inside it can be with
Strong current or air stream shear forces is avoided to wash away biomembrane.Filler has certain shearing for the air-flow in aeration tank
Effect improves the utilization rate of oxygen to a certain extent.And it can realize hydraulic detention time and sludge retention time
Separation ensures the quantity of active mud content in structures, so as to fulfill the efficient removal of pollutant.
Beneficial effects of the present invention are：The purpose that active carbon powder is added in filler is exactly to strengthen filler to microorganism and water
The suction-operated of nutriment and oxygen in body, in order to which microorganism can quickly realize biofilm；The purpose for adding in iron powder is one
Aspect regulates and controls the proportion of filler, contains iron and carbon component in another aspect iron powder, can be formed in waste water numerous small
Primary battery, organic matter is under the action of electric field, further Quick Oxidation reduction, so as to increase the biodegradability of waste water；It adds in and forms sediment
The purpose of powder, ammonium carbonate and potassium dihydrogen phosphate is that microbial growth provides nutritional ingredient, makes microbial film not easily to fall off, this
Also there is to adjust carbon, nitrogen in water outside, phosphorus ratio is unbalance；It is for microbial cell external respiration to add in iron and manganese oxides powder
Metabolism provides electron acceptor, enhancement microbiological metabolism.The appearance and internal structure design of this filler uniqueness can be adjusted with facilitating
Sluicing of the whole current to filler surface microorganism film, microorganism that on the other hand can also be on filler have huge with sewage
Contact area.
This filler has large specific surface area, and good hydrophilic property, bioactivity is high, and extension mould is fast, high treating effect, impact resistance
It is good, the characteristics of service life is long.
Description of the drawings：
Fig. 1 show the filling-material structure schematic diagram of the present invention；
Fig. 2 show the injection pictorial diagram of filler of the present invention；
Wherein, 1- blades, 2- vertical bars.
Specific embodiment：
For a better understanding of the present invention, below with specific example come the technical solution that the present invention will be described in detail, but this
Invention is not limited thereto.
Embodiment 1-3：A kind of floating stuffing for microorganism rapid biofilm, component is as shown in table 1 (used in the present invention
Iron and manganese oxides be purchased from Shanghai Venus chemical engineering industry Co., Ltd)：
Table 1
High temperature using 180 DEG C -230 DEG C melts high density polyethylene (HDPE), is matched according to above by active carbon powder, iron
Powder, starch, ammonium carbonate, potassium dihydrogen phosphate, iron and manganese oxides powder are added in the high density polyethylene (HDPE) of molten state, then pass through note
Modeling is fixed-type by filler.
The filler includes the blade 1 that multilayer is in tower-like arrangement, and every layer of blade 1 is 2-10 pieces, the bottom of every layer of blade 1 to
Center is gathered, and 1 top of blade radially distributes obliquely, and adjacent two layers blade 1 is in be spaced apart.Filler maximum gauge is
45mm, 1 width of blade are that the distance between 4-7mm, levels blade is 2-5mm, and every 11 back of blade is by bottom to top
There are the vertical bars 2 of an a diameter of 0.5mm.
Embodiment 1
Using identical preparation process, difference exists：Active carbon powder is added without in filler, obtained filler A is close
It spends for 0.95g/cm3。
Embodiment 2
Using identical preparation process, the difference is that：Starch is added without in filler, obtained filler B, density is
0.97g/cm3。
Embodiment 3
Using identical preparation process, the difference is that：Starch, ammonium carbonate and potassium dihydrogen phosphate are added without in filler,
Its density is 0.96g/cm3。
Three of the above filler is separately added into the beaker that 500ml fills clear water, after impregnating 10min, is surveyed using contact angle
Determine instrument to be measured, the contact angle of tri- kinds of fillers of A, B, C is respectively 65 °, 73 °, 84 °.The result shows that microbe carrier of the present invention
The clear water of filler is improved significantly.
The filler of identical quantity is taken, is marked using the cotton rope of different colours (red A, Huang B, green C), it is anti-to be placed in same biology
It answers in device, pH is in the range of 7.5-9.0, and temperature control is at 25-30 DEG C, BOD5/COD=0.3 or so, DO=1-2mg/l, COD
For 300mg/l, ammonia nitrogen 100mg/l, HRT=8h.The results are shown in Table 2：The biofilm time of such new packing is significantly lower than
General filler, COD and ammonia nitrogen removal frank are obviously improved.
