Description
Technical field
The present invention relates to the granular pattern multifunctional combination fillers of a kind of organic filler and inorganic filtrate, fill out for novel aeration
In the water purification technology for expecting chinampa, belong to restoration of the ecosystem field.
Background technique
As a large amount of nitrogen phosphorus enter water body, leads to the eutrophication of water field of big area, seriously affected expanding economy
With the life of resident.For the water body of eutrophication, every country and area using different physics, chemistry, biological method into
Row is administered, and has repaired the water body of eutrophication to a certain extent.It largely practices and studies have shown that ecological restoring method obtains
The universal approval of researcher.Artificial floating island is as one of water body in-situ recovery technique, compared to more other biological prosthetic
Technology has the advantages that significant.Water body environment is repaired using the absorption of plant and the catharsis of microorganism in chinampa, seeks to richness
Feedingization water quality has preferable catharsis；It is flexible in application, various water bodys are applicable to, and can be made various sizes, just
In transport；Chinampa can also beautify water environment, so, floating island technique is increasingly valued by people.
With the continuous development of floating island technique, researcher has found some disadvantages on traditional chinampa, such as plant type chinampa
It is seasonal obvious, and mainly by the pollutant in the harvesting removal water body of plant, not manageability, and the plant gathered in mostly at
For solid refuse, it is difficult to handle.In order to solve this problem, researcher has developed novel aerating filling chinampa, this kind floating
Island relies primarily on the biomembrane purification of filler, does not depend on plant, convenient for management, and has combined absorption interception function, strengthens and exposes
The technologies such as gas and plug-flow, effectively raise the clean-up effect on chinampa.
Currently used for the filler of floating island technique, there are two main classes, and one kind is organic filler, including fiber filler beam (soft,
Semi-soft and compounded mix) and granular pattern floating stuffing it is (annular packing, column filler, polyhedron empty ball homogeneous filler, built-in
Filler and porous rotation ball-shaped filling material)；The inorganic filler of another kind of predominantly light granules type, such as steel slag, zeolite etc..Comparison
Corpuscular filler, fiber bundle-like filler greatly reduce filler using conglomeration, clogging is easy to happen after a period of time
Available specific surface area influences its clean-up effect.
In order to improve dirt-removing power, researcher has done a large amount of research and innovation to filler, in the direction for improving filler
Constantly break through.Inorganic filler has preferable absorption property, can intercept the pollutant in water, and researcher is by some light-weight inorganics
It is used in chinampa after modification of filtration medium, achieves certain clean-up effect.It thanks to long blood et al. and has invented a kind of hanging for biological film process
Floating filler, is fabricated by volcanic rock powder, rubber powder and adhesive, is suitble to the Absorption Growth of microorganism, is easy to fluidize, mention
High treatment effeciency (application number 200910077129.1).Wen Baozhong et al. has invented a kind of active composite biological packing, by carrying
Body base-material and functional auxiliary material form porous carrier, and one layer of porous active powder substance is bonded on through-hole ball external surface
Layer, preferably improves the absorption property of filler, enhances the treatment effeciency (application number of COD and ammonia nitrogen
201210040598.8).Land rings et al. less has invented a kind of Suspension ceramsite filter material, is crushed using shale, powder processed, firing, sieve
Floating haydite is obtained after choosing, effectively raises specific surface area and mechanical strength, is suitble to the processing (application number of micro polluted source
201310239044.5).Although this kind of filler, by being modified, its essence is still inorganic filler, and there is no fundamentally change
The shortcomings that detergent power is lost after the disadvantage and adsorption saturation of carrier surface forming biofilm property difference.
The shortcomings that in order to overcome inorganic filler, the stability of filler detergent power is maintained, researcher fills out organic granular
Material has done numerous studies as floating stuffing.Han Hongjun has invented a kind of floating stuffing for sewage treatment, using soft or
Various shape is made in semi-soft resistant material, and vertical fin is arranged on surface, is effectively increased the specific surface area of filler
(application number 200410013528.9).Wangkai et al. has invented a kind of suspension water treatment filler, and helical structure greatly improved
The effective surface area of filler, and toxicity bioassay is not easily caused, there is excellent water treatmenting performance (application number
201010511103.6).This kind of filler, which mainly passes through, changes shape, structure to increase specific surface area, and then increases microbial biomass,
But its specific surface area amplification is limited, so the effect is unsatisfactory.Zhourong is rich et al. to have invented a kind of Wedge and plug-in combined suspending filling material,
The various fillers of plastic casing and internal attached microbial including outer layer, by effectively being further increased using space
The specific surface area (application 200610117939.1) of filler.It has invented a kind of efficient hollow grid shape spherical suspending and has filled out in Wuchuan et al.
Material, soft coarse fiber filament is wound on spherical structure, not only increases the specific surface area of filler, and will not cause fibre
It ties up silk conglomeration and causes waste (application number 200810200621.9).This kind of filler is intended to increase specific surface area by a larger margin,
But still without the inertia for fundamentally changing filler itself and increase biomembrane activity.
In order to further strengthen the detergent power of filler, researcher has also been made relevant from the modified angle of organic filler
Research.Tian Shuanhong et al. has invented a kind of suspended biological filler of porous surface, porous polymer materials bonding is coated to poly-
On olefin plastics skeleton, the hydraulic characteristic of filler is increased, can effectively retain the activated sludge of inoculation, promotes microorganism
Increment and metabolism (application number 201010154425.X).A kind of improved plastic filler of concrete has been invented by Wang Xiao army et al.,
It is attached to a layer concrete in frosting, improves the hydrophily of frosting, can effectively be improved micro- in water treatment system
The biofilm speed and biofilm intensity of biology.This kind of filler overcomes the inertia of filler itself by being modified to a certain extent, but
Its coat can reduce the specific surface area of script filler instead, cause the waste of material, and its production process is complicated, undoubtedly compared with
Big increases cost, it is difficult to promote.In order to overcome this disadvantage, Sui Jun et al. from change the angle of material composition to filler into
Row is modified, and has invented a kind of active filler, promotes the growth of microorganism by the way that biodegradable substance (such as starch) is added.
But the cruising ability of this kind of filler is poor, and organic matter is difficult to support the growth of excess microorganisms after decomposing completely, and can breed
Pathogenic microorganism, and the hole left also has an impact to the firmness of filler.Zhang Peng et al. has invented a kind of suspended biological
The hydrophily that magnetic powder, zeolite powder etc. improve filler is added in high density polyethylene (HDPE), increases biomembrane adsorption strength for filler.But
The characteristics of being due to production method, the functional component of this kind of filler is wrapped in the inside of plastic material more, and functional component adds
It is few to enter amount, plays a role faint, the waste of material but will be caused.
In conclusion can only improve biofilm biomass to the change of organic filler shape, structure, there is no fundamentally solved
The inertia of filler itself.Though and improving the biofilm speed of filler to a certain extent to the modification of organic filler and inorganic filler
Degree, biofilm intensity etc., but the ingredient being added is difficult to play preferable effect, and the effect is unsatisfactory, and production is complicated mostly.
Applicant early period studies have shown that a large amount of pollutants can be adsorbed to packing area by the absorption property of inorganic filler,
The pollutant of high concentration can stimulate the mass transfer to the inside of biomembrane, keep biomembrane thicker, and the combination of organic and inorganic particle
Space can be preferably utilized, the activity of biomembrane not only can be improved, but also the growth of biomembrane can be promoted, increases unit
The biofilm biomass of volume filler promotes purification of the filler to water quality.In addition, inorganic filler and organic filler will not be to ecological rings
Cause secondary hazards in border.So being a kind of higher mode of cost performance by the direct combination of organic filler and inorganic filler particle.
Scientific research personnel has done a large amount of research to this.
Zhourong is rich et al. to have invented a kind of functional suspended stuffing, and main body is that plastic plate grips particle material for water treatment
The compound wing plate being made into makes microorganism be easier to attachment and breeds (application number 03115913.3) thereon by the combination of filler.But by
Keep the utilization rate in space lower in its special structure, the density of microorganism is not high, and it is limited to improve purification of water quality ability.Tian Binghui
Et al. invented a kind of dual chamber suspended biological carrier, different environment more than general carrier, by adjusting carrier material,
Design vector chamber structure etc. forms the chamber of different purification functions, improves the efficiency (application number of biological treatment
201110102088.4).But this kind of filler is difficult to cope with the water quality of different parameters and form dual chamber environment, for example, processing is different
When the sewage of dissolved oxygen concentration, the size for needing to redesign carrier and each chamber just can guarantee different aerobic-anoxic environment,
There are higher specific aim, specificity, it is difficult to a wide range of to promote.Pan Yongzhang has invented a kind of microorganism suspended carrier of water process,
Float stone is packed into the plastics global shell of surface aperture (application number 200610132379.7), the coarse surface of carrier is suitble to micro- life
Object apposition growth substantially increases the removal efficiency of water pollutant.But its filler density is smaller, so that this kind of filler is answered
When for being aerated chinampa, the biomembrane of inner face can be fallen off due to shock and largely, the reduction effective specific surface area of filler, and its
40% filling rate is even more to have aggravated this phenomenon.
Granular pattern organic filler and inorganic filler do not easily cause secondary pollution, unlike plant chinampa due to its performance stabilization
It needs periodically to gather in, lasts a long time, be widely used in floating island technique.But the existing suspension that can be used for chinampa is filled out
Material, clean-up effect is unsatisfactory, and is easily delaminated using particle composite filling, reduced water and crosses gas rate.So for chinampa
Filler is improving detergent power, and reducing management difficulty etc., there is still a need for continue to develop and perfect.
