The normally understood meaning of technical staff is identical.Term as used herein in the specification of the present invention is intended merely to description tool
The purpose of the embodiment of body, it is not intended that in the limitation present invention.
As shown in Figure 1, a kind of biological filtering tower combined working for sewage treatment, including vertical tower body 1, vertical tower body 1 is interior to be equipped with extremely
A few filter element, at least one filter element include filter layer 11 and are supported on filter layer 11 for degradation of organic substances
Strain, dismountable feed inlet 12 is installed at the top of vertical tower body, shown in Figure 2, the bottom of vertical tower body is equipped with
Material mouth is connected to inside feed inlet 12, discharge port and vertical tower body 1.
Above-mentioned biological filtering tower combined working uses vertical structure, and occupied area is small, and quick and easy for installation, easy to operate, effluent quality is steady
Fixed, quality-high and inexpensive with strain using filtrate, input cost is low, and material replacement is convenient；And operating cost is low, power consumption only needs
0.1-0.15 member/m3.Above-mentioned biological filtering tower combined working equipment is suitable for rural area mountain area etc., and water outlet limited to land occupation requires not tight area
It is especially suitable, it can also be used as the supplemental facilities of the purification process techniques such as artificial swamp.
Specifically, sewage is transported at the top of tower body by water pump, under the effect of gravity, sewage is flowed into tower body, sewage
When flowing into the filter layer of filter element, which has retention, suction-operated, can remove SS, ammonia nitrogen, total phosphorus, CODcr.
Moreover, load has the strain for removing organic matter on filter layer, which has quickly breeding, spy easy to maintain of easily surviving
Point.It can be better than " integrated wastewater discharge standard " (GB8978-1996) primary standard by the water quality after filter layer or reach
" urban wastewater treatment firm pollutant emission standard " (GB19818-2002) level-one B standard.
In the present embodiment, in vertical column body 1 be equipped with 4 filter elements.It include one layer of filtering in each filter element
Layer 11, and filter layer 11 loads the strain for having degradation of organic substances.After sewage flows successively through every layer of filter layer 11, effluent quality can
To arrive discharge standard.
In the present embodiment, filter layer 1 is divided into aerobic reactor zone, hypoxia response area and anaerobic reaction area.
Hypoxia response area is mainly denitrogenation.In denitrification process, mainly plays denitrification removal nitrate nitrogen, go simultaneously
Except part BOD.
Anaerobic reaction is divided into 4 stages: (1) hydrolysis stage: macromolecule organic, cannot be direct due to its macromolecular volume
By the cell wall of anaerobic bacteria, needs to pass through ectoenzyme outside microbial body and resolved into small molecule.The organic substance of sewage,
For example cellulose resolves into cellobiose and glucose by cellulase, starch is broken down into maltose and glucose, protein
It is broken down into small peptide and amino acid.The carry out in vivo that these small molecules after decomposition can enter cell by cell wall is next
The decomposition of step；(2) acidification stage: above-mentioned small organic molecule, which enters in cell body, is converted to more simple compound simultaneously
It is assigned to extracellularly, the primary product in this stage is volatile fatty acid, while there are also alcohols, lactic acid, the dioxies of part
Change the products such as carbon, hydrogen, ammonia, hydrogen sulfide to generate；(3) produce the acetic acid stage: in this stage, the product of previous step is further converted
At acetic acid, carbonic acid, hydrogen and new cellular material.(4) the methane phase stage: in this stage, acetic acid, hydrogen, carbonic acid, formic acid
Methane, carbon dioxide and new cellular material are all converted to methanol.This stage is also that entire anaerobic processes are mostly important
Stage and entire anaerobic reaction process rate-limiting step.
In order to make filter layer 11 that there is preferable Nitrogen/Phosphorus Removal, a kind of new filter is had developed in one embodiment
Material is used for filter layer 11, which includes zeolite, clinker and porous baked brick.Using zeolite, clinker, porous baked brick as base
The new packing of matter makes full use of the feature that the packing specific area is big, adsorption capacity is big, the quick CODcr retained in sewage,
The pollutants such as ammonia nitrogen, total phosphorus, SS, wherein zeolite has ammonia nitrogen absorption effect, and clinker has denitrification functions, and porous baked brick has
COD degradation function, filler itself have SS retention functions.
Further, the volume ratio ratio of the three of zeolite, clinker and porous baked brick is 1:1:0.5.In the ratio
Under, filter layer 11 has best Nitrogen/Phosphorus Removal.
In the present embodiment, strain is aerobic biological inoculum, anaerobic organism strain and and oxygen biological inoculum.
Further, anaerobic organism strain includes hydrolytic bacteria, acidification bacterium, acetic acid bacteria and methane backeria etc., good sample biological inoculum
Including most of bacteriums, actinomyces and fungi etc., and oxygen biological inoculum includes saccharomycete or Escherichia coli etc..
In order to make vertical tower body 1 that there is sufficient oxygen to promote strain removal polluter, in a preferred embodiment,
7 ventilation holes being in communication with the outside are equipped between filter element described in every two, specifically, referring to Fig. 3,4 and 5.
The height of vertical tower body 1 can be designed according to the size of water, in a preferred embodiment, vertical tower body 1
Height be 4m.In other preferred embodiments, the height of vertical tower body 1 can be 1m, 2m, 3m, 5m, 6m, 7m and 8m.
Further, the distance between filter layer is 0.2-0.3m.The distance can guarantee that enough sewage connects with air
The touching time reaches the biochemical reaction that oxygenation purpose is beneficial to aerobic zone.Filter layer with a thickness of 0.4-0.8m.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
