The basic technology of Production of Ceramics are as follows: particle, molding, drying, firing, post-processing.According to forming technique difference, building
Ceramic process can be divided into two classes, one kind be it is dry-pressing formed, another kind of is extrusion forming.But the roughly the same master of waste water that they are generated
It to include three parts, i.e. grinding and polishing waste water, flushing waste water, tail gas clean-up waste water.Put into sanding and polishing, ground and equipment are rinsed,
Water in the workshop sections such as tail gas clean-up, by using the waste water for becoming different: sanding and polishing water will carry grinding and polishing break flour and mill
It throws the pollutants such as agent and is converted into grinding and polishing waste water；Ground and equipment rinse water will have raw material powder, atmospheric falling dust, greasy dirt
And it is converted into flushing waste water；Tail gas clean-up water by dust, the dissolubility pollutant in absorption tail gas, and residual detergent and
The product that detergent and pollutant reaction generate, is finally translated into tail gas clean-up sewage.
The pollutant kind that the waste water of separate sources contains is different from quantity.If collection is taken to summarize, at concentration
The mode of reason, just will increase the difficulty of wastewater treatment, and be unfavorable for recycling for waste water.Classification recycling, purification and circulation
Utilize the basic principle for being processing ceramic wastewater.
The processing of grinding and polishing waste water
Sanding and polishing waste water is a kind of Ceramics Enterprises maximum waste water of discharge amount when producing polished bricks.It contains pollutant
Mainly there are the solid particulate matters such as polishing agent, grinding and polishing powder, grinding agent, also there is a small amount of mechanical greasy dirt.According to sanding and polishing waste water
Feature, can be by solid particulate matter removal most of in waste water using rectangular sedimentation tank.It will contain in primary water a certain amount of
Fine suspended matter needs that flocculant is added if being completely removed, using precipitation process.Although the precipitating of flocculant is added
The available more clear water outlet of processing, but cost is relatively high；And the water outlet that direct precipitation process mode obtains contain it is a certain amount of
Fine suspended matter, but lower can also send to grinding and polishing workshop section of processing cost and be recycled.
The processing of flushing waste water
Flushing waste water source is complicated, the flushing waste water including the equipment such as ball mill, spray drying tower and ground.All kinds of waste water
Yield and drain time it is unstable, processing will greatly increase operating cost.So taking centralized processing, it is conducive to handle
The stabilization of equipment continuously run with inflow.Pollutant after collecting, converging is mostly derived from the leakage slurry sedimentation of raw material
The powder and lubricating oil on ground etc..Since the major pollutants contained in flushing waste water are subtle suspended particulate substances, belong to glue
Body disperse system, colloid surface have negative electrical charge, it is therefore desirable to coagulant be added in the waste water of processing, compression double electric layer destroys
The stability of colloid thus muddy water separation.Again since COD (COD) and suspended matter (SS) is positively related relationship, institute
Will mainly control the SS factor.Specific flushing waste water processing technological flow are as follows: it is laggard that waste water through grid removes coarse suspended matter
Enter just shallow lake pond, enters horizontal sedimentation tank after the mixing of aluminium polychloride (PAC) coagulant is added.Suspended matter and coagulant in water pass through
Hydrating polymer is formed after crossing reaction, generates electric double layer compression, and adsorption bridging and polymeric precipitation, supernatant water just flows into clear water reserviors can
To recycle.
The processing of tail gas clean-up water
The production of ceramics is the process of a heavily contaminated, and exhaust gas therein is mainly that high-temperature gas and industrial dust two are big
Class is mostly derived from the tail gas of spray drying tower and kiln release.Waste water will be generated during handling these tail gas.Tail gas
Whether output waste water depends primarily on tail gas clean-up technique to purification process.Only use the wet process tail gas clean-up of gas scrubbing technology
System just has the generation of waste water.The reaction principle of wet process exhaust gas purification system is different, and the waste water of generation is also different.But processing is former
It is then similar, i.e., by waste water after precipitation process, supernatant is isolated using alkaline matter and readjusts pH value, becomes alkalinity
Absorbing liquid recycles.
Micro-filtration film process ceramic wastewater is mainly exactly the crown_interception using film surface, but is contained in the waste water of some
There are a large amount of impurity particles, chemical reagent is added into waste water solution first, this kind of chemical reagent can be with the impurity in waste water solution
Ion and molecule occur chemical reaction and generate biggish solid impurity.Impurity can sink to bottom, then use microfiltration membranes again
It is handled, filter opening would not be made to block because of solid particle in waste water.It can accelerate the speed of wastewater treatment.
Microfiltration membranes prepare the stream that high purity water generallys use as absolute filtration in electronics industry, semiconductor and medical industry
Cheng Shi；Stoste → flocculation sedimentation → sand, anthracite filtering → chlorination antivirus → pre-filtering → reverse osmosis → positive and negative ion exchange are mixed
Close bed → micro-filtrate membrane filtration → user.
The main function of micro porous filtration in high purity water preparation: the activity that each unit discharges in water system is made in 1. prevention centers
Carbon dust, resin-oatmeal, microorgranic contaminant enter distribution system；2. reducing the particle pollution level of user.In medical industry, note
The removal for penetrating particle matter in liquid can also use the processing means of micro porous filtration.Pure water or high-purity water system are usually to locate in advance
Reason increases aftertreatment technology on the basis of water quality desalination, and aftertreatment technology be mainly deep desalting and by micro-filtrate membrane filtration and
Sterilization keeps water quality qualified.Common after-treatment system can be divided into two kinds: using terminal installation system and closed circulation post-processing system
System.
The main isolated viral of micro-filtration, bacterium, colloid and suspended particulates, to separate the subparticle for being greater than 0.05 micron.?
The removal of bacterium and particle, the detection of biology and microorganism have unique effects in the purification of water, drug, and application is very extensive.
Mineral water production
Ceramic micro filter film is a kind of excellent inoranic membrane, obtains good effect in the production for mineral water.By phreatic water
Enter ceramic micro filter film device after sand filter pump, the water of filter membrane meets state health standards, and transparency significantly improves, performance
Stablize.1m3Device water yield 1m3/ h or more, cleaning is primary weekly, easy to operate, is the key link of pure water production.
Oil field produced water process
Oil well produced most of the surface layer crude oil of most domestic is oil-water coexistence, after water-oil separating, recovered water
Recharge is wanted to prevent the sinking of the earth's crust to the depths on stratum.Requirement to recharge water is to remove 0.5 micron or more of suspended matter and thin
Bacterium.Suspended matter is less than 1mg/L, and oil content is less than 2mg/L.And the mineral degree of recovered water itself is high, the high water temperature of suspension content
Also high, it handles relatively difficult.But it can be solved back using polypropylene hollow fiber micro-filtration film device as ultimate filter
It fills and requires, the oil field produced water process for each elephant in the whole nation provides a kind of novel solution.
City sewage deep treatment
At present since water source is in short supply, many countries are all actively carrying out processing and reuse to municipal sewage, and Japan then wants
Asking channel system setting to be strict with can just put into operation.The plan of water channel water process and target are as follows in Japan: miscellaneous
Draining → the screen to filtrate → residue removal → adjustment tank → pressure floatation → catalytic oxidation → micro-filtrate membrane filtration → sterilizing → lavatory
With water storage tank → lavatory water.After two stage treatment micro-filtrate membrane filtration make to handle during water reaches as advanced treating means
Water quality standard reuse.
Otherwise application
Hospital, the medicament of pharmacy and Microbiological Lab and solution must be sterilizings, and microfiltration membranes can be very convenient
Economically prepare this kind of sterile solution.Microfiltration membranes of the aperture less than 0.5 micron can remove wherein after being filtered to beer
Yeast, mould and other microorganisms.Treated in this way, and beer will be more as clear as crystal, improves resting period reduction
Cost.Previous draft beer is the original flavor that can keep beer using micro-filtration membrane technology now by high-temperature sterilization, greatly
The big quality for improving draft beer.In addition, the pore size of different microfiltration membranes can have different purposes.Aperture is 12 microns micro-
Filter membrane can be with the suspended matter in separation of bacterial liquid.Aperture may be used as the survey of industrial dust's weight in 3 to 8 microns of microfiltration membranes
It trying, the purification of sugar, the measurement of malt precipitation capacity in Beer Brewage is also used in cytology research, and encephalomyelic marrow liquid diagnoses,
The detection of particle in industrial machine internal combustion engine and oil pump.Aperture is in 1 to 2 microns of microfiltration membranes in yeast and the microscope of mould
Monitoring, dust weight analysis have certain purposes.Microfiltration membranes inspection as in milk Escherichia coli of the aperture at 0.6 to 0.8 micron
It surveys, the residue measurement of liquid, the aseptic filtration of gas, oils clarification filtration, the control of noble metal tank liquor quality, there are also radioactivity
The quantitative analysis of aerosol, the clarification filtration of photoresist.0.45 micron of microfiltration membranes can be used in the survey of drinking water phosphate radical
Fixed, the quality control of aviation oil and other oil plants, insulin radioimmunoassay, there are also hemocytometers for the ultrapurification of deionized water
Number electrolyte solution has purification purposes, measures the iron hydroxide content in boiler water, the color calibrating of white sugar etc..02 micron micro-
Filter membrane can be used in medical fluid, the aseptic filtration of biological agent and thermosensitive liquid, viral quantitative determination, uropoiesis liquid microscopy in air
With the degerming of water.0.01 to 0.03 micron of microfiltration membranes can be used in the separation of bacteriophage and larger viral (100 to 250 nanometers),
Thicker aurosol can also be separated.
Conditioner is added into stoste, effect is that the impurity in stoste is made to be easy to get together, to reduce filtering
Resistance, then tested, experimental result improves significantly that the experimental result of conditioner is not added than before.It can be seen that microfiltration membranes
Chemical agent, which is added, in processing waste water can effectively improve the efficiency of filtering, and water outlet is made to reach ideal effect.
Since the 1990s, China just has become maximum architectural pottery producing country and country of consumption in the world.But
It is that current builds the process that pottery production is a high resource and energy consumption, environmental pollution again, in a large amount of natural mineral moneys of consumption
While source, the energy and water resource, along with serious pollutant emission problem.And the solution of the pollution problem of ceramic wastewater is just
