2, removal organic pollutant such as Fenton reagent mainly concentrates on the removal aspect of the aromatics with bio-toxicity, and when photochemical catalysis and ozone are linked together, not only improved removal efficient, and saturated organic compound is degraded aromatics.Tradition thinks that photochemical catalysis can only handle low concentration wastewater, and need the very long residence time, behind the combined with ozone oxidation technology, and the photocatalysis technology range of application that has improved organic matter degradation rate greatly and expanded.There is very strong advantage in photochemical catalysis-ozone oxidation system in water treatment field, its applied range, but multiple high concentration hard-degraded organic waste waters such as treatment of dyeing and printing, coking chemical waste water, percolate waste water, electron trade waste water.
As shown in Figure 2, membrane bioreactor:
Membrane bioreactor (MBR) technology is the combination of membrane separation technique and biotechnology, it has realized thoroughly separating of hydraulic detention time and sludge retention time, increased the activated sludge concentration in the bio-reactor, thereby strengthened the organic biological degradation in the waste water.In addition, MBR has also that floor space is little, and processing speed is fast, and sludge discharging period is long, advantages such as stable effluent quality.Can be applied to the processing of trade effluent, in beer waste water, paper waste, dyeing waste water, coking chemical waste water, power plant in the processing of water reuse etc.

Optimization system constitutes energetically: 1) the pond body is welded by carbon steel and shaped steel etc., which is provided with water-in and water-out pipeline and emptying pipe, makes the pond body of corresponding specification according to the size of treatment capacity, is the work-ing life that prolongs the pond body, and the pond body must be through specific anticorrosion.2) membrane module is the core component of this apparatus module, the quality of effluent quality and processing cost have direct relation with it, according to different water quality requirements, the general membrane module of selecting is also inequality, because price factor, generally all select organic membrane, the aperture of film is between 0.2～0.4 μ m, and membrane flux is 10L/ (m
2H).3) blast aeration system adopts gas blower+perforated pipe aerating regulation system, and simple and reliable, pipeline is provided with the aeration intensity that variable valve is adjusted membrane module, pollutes to alleviate film.
The selection of film: existing film can be divided into two kinds of organic membrane and mineral membranes, and mould material commonly used is polyethylene, polypropylene etc.Separate type MBR adopts hyperfiltration membrane assembly usually, and molecular weight cut-off is generally 2～300,000.Molecular weight cut-off is big more, and the initial film flux is big more, but the long-time running membrane flux may not be big more.The flux die-away test of mineral membrane shows: the film of aperture 0.2 μ m is more suitable in MBR than the film of 0.8 μ m.Test finds that the initial flux decay of film mainly is because concentration polarization causes that retaining molecular weight is littler, and the flux rate of fall-off is bigger; The flux decay of film long-time running mainly is to cause that retaining molecular weight is bigger because film pollutes, and the flux attenuation amplitude is bigger, and the matting recovery rate is lower.For submerged MBR, both available ultra-filtration membrane also can use microfiltration membrane.Because the gel coat on film surface has also played filteration, when handling sanitary sewage, the effluent quality of microfiltration membrane and ultra-filtration membrane does not have significant difference, so submerged MBR 0.2～0.4 μ m microfiltration membrane that adopt more.
The improvement of hydraulic characteristic: for integral type film biological reactor, flow passage structure reasonable in design improves intermembranous liquid upflow velocity, and the cross flow filter effect that bigger aeration rate is played wash away the film surface seems particularly important.Under same aeration intensity, reactor is high more, and the upwelling passage is narrow more, and katabatic drainage passage and foot passage are wide more, then can obtain bigger intermembranous cross-flow flow velocity more.
The optimization of operating method: after mould material was selected, its physico-chemical property is also just basic had determined that operating method just becomes influences the principal element that film pollutes.For decelerating membrane pollution, aeration is an important operation of keeping the steady running of separate type membrane bioreactor, shorten suction time or prolongation simultaneously and stop the suction time and increase aeration rate all to help decelerating membrane pollution, suction time has the greatest impact to the rising of membrane resistance, and aeration rate secondly.According to above-mentioned experimental result, my company determines best aeration rate and suction time.
Automatic control system: the automatic control system of this device will be based on industrial control computer, select for use by programmable logic controller (PLC) and field instrument, field control equipment and form.Realization is to the functions such as detection, control, warning, interlocking and accident treatment of whole process system.So that satisfy the needs of various operation conditions, guarantee the safety and economic operation of process system.Supervision and management function are undertaken by the touch-screen of operator station.So get hold of design, Software development, the component configuration also is crucial.
The utility model can effectively be handled the used water difficult to degradate of industries such as coking, printing and dyeing, and water outlet can reach city miscellaneous water water quality standard, is manufacturing enterprise's conserve water resource; This device is made up of photocatalysis and ozone oxidation reactor and the big module of membrane biological reaction tolerance, the assembling convenient transportation, and the composite design mode is flexible, and Operation and Maintenance is simple; The photocatalysis and ozone oxidation technology has overcome the shortcoming of traditional advanced oxidation processes, and treatable used water difficult to degradate kind is extensive, with the organic combined utilization of membrane Bio-reactor Technology, stable effluent quality.
