Description
Technical field
The utility model is related to method for treating water and water treatment facilities, and in particular to a kind of ceramic membrane aeration and it is critical it is micro- just
Ozone is pressed to carry out the regenerated water treatment facilities of film.
Background technology
Earthenware slab membrane bioreactor is as a kind of new and effective sewage disposal technology, it has also become sanitary sewage, industry
Waste water（The particularly waste water containing aromatic hydrocarbon）With extreme environment waste water（Such as butcher and breeding wastewater）It is indispensable in processing
Treatment technology.
Ceramic membrane becomes sewage-treatment plant core component, and good result is achieved in practice.But system
Because organic matter and inorganic matter absorption are in membrane surface in filtering operation, particularly bacterium and microbe metabolite be easily and metal
Ionic interaction forms layer of gel layer in film surface, or bacterium in ceramic membrane surface implantation and can be tightly adhered to film surface
On, coating layer is formed, causes diaphragm channel blockage flux to decline.Filtering just needs to divide diaphragm progress backwash 1 for 10 ~ 30 minutes
Clock, and backwash water and pressure will be increased to 2 times, cause equipment work efficiency there was only 70% or so, equipment operating cost carries
Height, cost of investment increase；And the time has grown bacterium and easily bred, further result in dirty stifled, it is necessary to be washed with solvent medicine, further
Reduce filtration time and reduce total filter efficiency.And all salts containing soda acid and oxidant and the medicament of enzyme detergent class are equal
Other salts substances can be generated, or even has partial salts material to form gel group in film surface with bacterium colloid group and brings gold into
Belong to ion, cause secondary accumulation pollution, and pH value can be changed, derive other problem of environmental pollution.For these problems, state
Interior useful ozone and back-flushing and the method for solution mixing backwash, but because ozone utilization rate is low, probably only 5%-20%, is caused
Cost of use is expensive, and the ozone for causing part not utilize is discharged into air and causes air pollution and the harm to human body.
In addition the existing boring aeration largely used and aeration plate are aerated using macropore, and there are the utilization rate pole of oxygen
The shortcomings of low, waste of energy, filling is uneven, is aerated head material in extreme circumstances and is easily corroded decomposition, short life.
Utility model content
In order to solve flat ceramic membrane module in the prior art, easily the deficiency of simultaneously frequent clean is blocked up in dirt in application process,
The problem of ozone utilization rate is too low and causes running efficiency of system to reduce, and operating cost is high.To solve problem above, this practicality is new
Type provides a kind of ceramic membrane aeration and critical micro-positive pressure ozone carries out the regenerated water treatment facilities of film.
The ozone generator uses air source ozone occurrence of equipment, and cost is controllable.The ozone generator outlet is divided into
Two-way, enters pretreatment pool by solenoid valve all the way and carries out microvesicle aeration, main oxidation decomposes the organic matter of most of difficult degradation
And reduce COD indexs etc..New process of employing new technology is handled, and ozone decomposed oxidation is fully carried out, is greatly improved
The effective rate of utilization of ozone and the time with waste water.Using new product nano ceramics aeration membrane as aeration board, increase
Aeration area and increase micropore quantity, and use critical micro-positive pressure, ozone is gradually formed microvesicle, and slowly increase, arrive
Depart from aeration membrane surface, next bubble slowly produces again, so circulation.Whole bubble from formed to departing from all and around
Organic matter carry out oxygenolysis, and because using nano ceramics film aeration membrane as hole substrate, the bubble of generation is non-
Chang Wei little, considerably increases the quantity of bubble and the surface area with waste water.The overcompression when PC-MBR systems use
Air carries out the micro- continuous-pressure breathing gas of microvesicle, there is provided ultra-fine source of oxygen bubble, makes full use of source of oxygen, reduces unnecessary energy wave
Take；Another way enters membrane cisterna by other solenoid valves and exports back flush to the stifled ceramic membrane of dirt, uses critical micro-positive pressure
Microvesicle is slowly produced, after oxygenolysis rapidly and efficiently is carried out using ozone, used air compressor machine departs from pollutant purging hollow
Flat ceramic diaphragm surface, plays the purpose for recovering flux, reduce that solvent washes costly and causes asking for secondary pollution
Topic.The hollow ceramic tablet diaphragm uses high purity aluminium oxide as carrier extrusion forming, single with 30-90 on its cross section
Arrangement and the hollow hole of up/down perforation.Set inside the hollow ceramic flat membranes piece with 0.5~5 μm of micropore, outer surface
There are transition zone, transition layer surface plating 0.01~0.2um microporous barriers.
The nano ceramics film aeration membrane makes of high purity aluminium oxide, corrosion-resistant and extreme environment, particularly organic molten
Agent is with the obvious advantage, thus it is preferable used in high dangerous waste place aeration effect, and service life extension several times, reduce the later stage and replace the frequency.Institute
Different pore size ceramic membrane can be made as requested by stating（Aperture can be used for being aerated from 0.1um ~ 100um）, easy to corresponding different
The requirement of aeration form（Such as boring aeration, aeration plate aeration, micro-pore aeration etc.）, nano ceramics film aeration membrane can be tablet
Ceramic membrane, pillar honeycomb ceramic body, the microporous inorganic material ceramics of DPF diesel particulate filters ceramic monolith or other shapes
Body.The aperture of micropore is the plurality of specifications such as 1 μm ~ 50um in the hollow ceramic flat membranes, and porosity is 20%~75%.This
Sample adapts to the place of different requirements.The aeration membrane can be placed with individual layer or multilayer is placed, and further improve ozone utilization
Rate, so that the thrifty energy and space.The length of the nano ceramics film aeration membrane is 150-1000mm；Set in parallel or series
Put, the Ullage of adjacent two nano ceramics film aeration membrane is 2-200mm；The nano ceramics film aeration membrane uses high pure oxygen
It is carrier extrusion forming to change aluminium or kaolin or other viscous materials, and appearance and size is wide by 110,150mm, 250mm thickness 3-8mm, length
150-1000mm is spent, upper and lower end face is by 32-60 hollow hole single-row arrangement and up/down perforation, and the aperture of micropore is on sintering carrier
1-50 μm, centre plating transition zone, and distribution of pores is narrow.
The ozone generator uses air source ozone occurrence of equipment, and the ozone generator outlet is divided into two-way, all the way
By solenoid valve enter pretreatment pool carry out microvesicle aeration, whole bubble from is being formed to departing from all and around organic matter progress
Oxygenolysis, and as hole substrate, the bubble produced is very small, greatly increases because using nano ceramics aeration membrane
The quantity of bubble and the surface area with waste water；Another way blocks sewage into membrane cisterna by other solenoid valves hollow
After flat ceramic diaphragm carries out oxygenolysis rapidly and efficiently, used air compressor machine purging departs from hollow ceramic flat membranes piece surface,
Play the purpose for recovering flux.Reduce costly and the problem of causing secondary pollution that solvent is washed.
