Abstract
The present invention relates to a kind of biological film fluidized bed wastewater treatment method, belong to field of environment engineering.This method is to be used as fluid bed carrier filler using the good natural pulp fiber of bioaffinity, and three Room composite biological film fluid beds of use are as fluidized-bed reactor.This method can substantially reduce power consumption.Simultaneously as having many fiber fines and micropore on paper pulp fiber, be conducive to the growth and attachment of microorganism, and the bridging of fiber fines and trapping act on, and largely solve the problem of microorganism easily comes off existing for conventional fillers.This method has a good application prospect.
Description
Technical field
The present invention relates to a kind of biological film fluidized bed wastewater treatment method, belong to environmental project technical field of waste water processing.
Background technology
Bioremediation has become the main body treatment technology of sanitary sewage, municipal sewage and organic industrial sewage at present,
Activated sludge process and contact oxidation method in these technologies need to be oxygenated to the aerating wastewater in reaction tank, handle every cubic metre of waste water
Aeration aerating will at least consume electric energy 1Kwh, and treatable Wastewater Pollutant load is relatively low, and impact resistance is smaller；With life
Though thing filter tank and biological rotating disk are not required to aeration aerating to handle waste water, the volumetric loading of reaction tank filler is low, system denitrogenation effect
Fruit is poor, and reaction tank volume is big, takes up a large area, and investment is big；In order to further reduce the appearance of the energy consumption of sewage disposal and filler
Product load, many countries all open in research biomembrane fluidized bed processing technology and new bio compatibility filling in the world at present
Hair.
Chinese patent CN101386447 discloses a kind of " biofilm fluidized bed reactor is hit in interior circulation ", is being aerated
Part substitutes traditional bubbling device with internal circulation impinging stream absorber, improves the dissolved oxygen content in water, improves treatment effeciency.
But because throttling action airflow rate is excessive, cause biofilm detachment, so as to influence treatment effect；Chinese patent ZL
200610151903.5 disclose it is a kind of " using fluidized-bed process treated sewage method and its organism compatibility filling and its fill out
The preparation method of material ", the invention prepare a kind of new graininess using polyurethane, rare earth metal and ferrous oxide etc. and fill out
Material, to improve the bioaffinity of filler.But because of filler metallic components, density is higher, cause in reactor operational process
Gas lift load is high, and power consumption is big.
The content of the invention
It is an object of the invention to provide a kind of improved biological film fluidized bed wastewater treatment method, to overcome existing biology
Film fluid bed there are the problem of.In view of conventional fluidization bed is generally single chamber or dual chamber, there are gas lift load is larger, aerodynamic force disappears
The problems such as consumption is high, and biomembrane is easy to fall off, the present invention proposes " three Room composite biological film fluid beds " new concept, by conventional fluidization bed
Gas lift load is decomposed into gas lift load and rises load with liquid, reduces gas lift dynamic load(loading) and gas flow rate, effectively avoids biomembrane
Come off.Meanwhile and density good using bioaffinity and the close new packing of water.
According to above-mentioned design, the present invention uses following technical scheme：
A kind of biological film fluidized bed wastewater treatment method, it is characterised in that by the use of natural pulp fiber as biological film fluidized bed
The filler of reactor.
Above-mentioned natural pulp fiber is chemical wood pulp, chemical straw pulp, choose any one kind of them in mechanical pulp and chemi-mechanical pulp or
It is several.
The dosage of the filler of above-mentioned biofilm fluidized bed reactor is the 0.1%-1.0% of reactor volume（By over dry
Paper pulp calculates）.
Above-mentioned biofilm fluidized bed reactor is three Room composite biological film fluidized-bed reactors.The reactor by circle outside
Cylinder（1）, circular shunt cylinder（2）, circular up-flow cylinder（3）, standing separation partition plate（4）, gas-liquid mixed tank（5）, intake pump（6）, gas
Pump（7）, circulating pump（8）, aeration head（9）, former bucket（10）Composition.
Above-mentioned reactor is made of three Room, is respectively：Circle up-flow cylinder（3）Interior cylindrical space is the first Room, circular
Shunt cylinder（2）Cylinder is flowed up with circle（3）Between annular space be second Room, circular outer cylinder（1）With circular shunt cylinder（2）Between
Annular space is the 3rd Room.
Compared with the conventional method, this method has the characteristics that will be apparent below and advantage：
1st, since natural pulp fibre density and water approach, power consumption is greatly reduced；
2nd, due to having many fiber fines and micropore on paper pulp fiber, specific surface area is big, be conducive to the growth of microorganism with
Attachment, the bridging of fiber fines and trapping effect, largely solve microorganism existing for conventional fillers and easily come off
The problem of；
3rd, the good natural pulp fiber of bioaffinity is used as reactor filler, solves conventional inorganic filler and organic
The defects of bioaffinity is poor existing for synthetic filling；
4th, due to using the compound flow mode of gas-liquid, gas lift load is reduced, greatly reduces gas flow rate, so as to mitigate
The coming off of biomembrane.
Therefore, compared with traditional biological film bed process, the present invention can substantially reduce power consumption, avoid biomembrane
Come off, improve the bioaffinity of filler, so as to reduce cost, improve waste water treatment efficiency.
Brief description of the drawings
Three Room composite biological film fluidized-bed reactor of figure.
