Description
Technical field
The invention belongs to water process carrier technique fields, and in particular to a kind of water process ceramic honey comb and its preparation side
Method.
Background technology
With the rapid development of a variety of industries such as industry, aquaculture, the sewage composition that every profession and trade generates is more and more multiple
It is miscellaneous, higher want is proposed to how safe, green, the industry that inexpensively processes composition becomes increasingly complex, agricultural, sanitary sewage
It asks.Biological wastewater treatment technology is consumed less with it, is efficient, at low cost, technological operation manages convenient and reliable and non-secondary pollution
It waits remarkable advantages and receives the favor of people.
Bioanalysis is broadly divided into activated sludge process and fixed embrane method, and fixed embrane method is that one kind arranged side by side with activated sludge process is given up
Water Aerobic biological process technology is a kind of fixed embrane method, it is in the microorganism on some solids surfaces using apposition growth（I.e.
Biomembrane）The method for carrying out organic sewage processing.Biomembrane be by the aerobic bacteria of highly dense, anaerobic bacteria, amphimicrobe, fungi,
The ecosystem of the compositions such as protozoan and algae, the solid dielectric of attachment are known as filtrate or carrier.Biofilm has
Advantages below：（1）Water, water quality, water temperature are changed adaptable；（2）High treating effect simultaneously has good nitrification function；（3）It is dirty
Mud amount is small（About the 3/4 of activated sludge process）And it is easy to separation of solid and liquid；（4）Power cost saves.The above advantage to fix
Water treatment by membrane has more and more wide application in industry, the directions such as municipal wastewater processing, aquaculture.
The key material that microorganism carrier is then fixed embrane method is attached with, it is necessary to have Material Strength height, specific surface area
Greatly, stable chemical performance, the features such as porosity is high.Specific surface area is bigger, and biomembrane is bigger, and biomass is more, detergent power
It is stronger；Porosity is higher, and filter bed is not easy to plug, and has more oxygen to be passed through, and preferably oxygen metabolism provides favourable conditions；Material is strong
Degree is high, and the load that when operation can carry is also bigger；Stable chemical performance be just not easy with water react or outwards discharge other from
Son will not cause secondary pollution.
Fixing the microbe carrier of embrane method at this stage has porous carbon, river sand and ceramic corrugated plating etc..The ratio table of porous carbon
Area is high, but intensity is low and is graininess, can not bear big hydraulic load, and porosity is smaller, and water resistance is larger during operation, can not
Preferably oxygen metabolism provides enough oxygen.The granule strength of river sand is higher, but specific surface area is smaller and porosity is smaller, attachment
Microorganism it is limited and run when water resistance it is very big, preferably oxygen metabolism provide oxygen deficiency.The intensity of ripple ceramic is preferable, porosity
Greatly, water resistance is small during operation, but specific surface area is small, can not adhere to too many microorganism.Therefore prepare a kind of of good performance solid
Determining membrane carrier becomes fixed embrane method sewage disposal urgent problem to be solved.
The content of the invention
In view of this, it is an object of the invention to provide a kind of intensity it is high, be not easily broken, large specific surface area, porosity are big, change
The ceramic honeycomb that performance is stablized is learned, while the present invention also provides a kind of preparation methods of the ceramic honeycomb.
The technical solution adopted in the present invention is：
A kind of water process ceramic honey comb, is made of the raw material of following weight percent：Framework material 50-90%, pore creating material 4-
30%th, binding agent 5-30% and lubricant 1-10%.
Further preferably, which is made with ceramic honey comb of the raw material of following weight percent：Framework material 65-
75%th, pore creating material 10-15%, binding agent 13-21% and lubricant 1-5%.Framework material is quartz sand, and pore creating material is powdered carbon, graphite
One or more in powder, starch, binding agent for starch, malt syrup, tung oil, cellulose, polyvinyl alcohol, one kind in water or
A variety of, lubricant is oleic acid, the one or more in atoleine, vegetable oil.
The preparation method of water process ceramic honey comb, comprises the following steps：1）Various raw materials are taken in proportion；
2）Framework material, pore creating material are crushed respectively, then mixing carries out kneading, dry-mixed, adds in binding agent and lubricant afterwards
It mediates；
3）By step 2）It is aging after kneaded thickener sealing, it is aging after thickener be kneaded, the mud being kneaded is by different rule
The honeycomb dies of lattice squeezes out, the wet feed roasting of extrusion, and cooling discharging post-processing is into the specification of needs.
Step 2）Using kneading pot, dry-mixed at least 30min during kneading；At least 1h during kneading.
Step 2）Framework material is crushed to below 200 mesh during middle crushing, pore creating material is crushed to below 300 mesh.
Step 3）The aging time is 2-3 days, and 2-3 times during mixing, the wet feed of extrusion dries in the air 2-3 days before roasting；Calcination temperature is
750-900 DEG C, roasting time 3-5h.
The present invention has selected suitable framework material, pore creating material, binding agent, lubricant, while employs suitable preparation
A kind of ceramic honeycomb has finally been made in method, the ceramics have intensity height, large specific surface area, porosity greatly, stable chemical performance
Good characteristic, can be as the microbe carrier of fixed water treatment by membrane, in industry, municipal sewage treatment, aquaculture etc.
Industry has very wide application prospect.
