Description
[technical field]
The utility model belongs to field of environment engineering, particularly a kind of immersion flat sheet membrane aerobe reactor.
[background technology]
Activated sludge process (Activated Sludge Process) is the biological wastewater treatment technology based on active sludge, under the condition of artificial oxygenation, cultivate acclimated microorganism colony, this have active microorganism flocs unit and be called as " active sludge ", utilize the absorption and the biochemical oxidation effect of active sludge, remove dissolved and colloidal organic substance in the waste water to decompose, waste water is purified.The activated sludge biochemical reaction makes microorganism obtain procreation propagation, and active sludge itself obtains increasing, and active sludge separates with waste water by precipitation, and the waste water after the clarification is discharged system as the water outlet after handling.In more than 90 year that founded so far in 1914, the theory and technology development of activated sludge process rapidly.The activated sludge process of main flow mainly is divided into three major types at present:
Traditional activated sludge process and deformation technique thereof comprise traditional activated sludge process, step aeration system, tapered aeration, complete hybrid system, extended aeration process etc.The common trait of the aeration tank in these technologies is a continuous flow reactor, and the function of aeration tank mainly is to remove the carbon containing organic pollutant.These class methods can only be carried out the nitrated of ammonia nitrogen to a certain extent, and do not possess biological denitrificaion and biological phosphate-eliminating effect.
Second class is an oxidation ditch process, and this is a kind of activated sludge process of modified form, and its aeration tank is the irrigation canals and ditches type of sealing, and waste water and active sludge intermixture circulate therein.Oxidation ditch process combines plug-flow and mixes two kinds of fluidised forms fully, thereby has stronger anti-load impact ability; On the other hand, dissolved oxygen concentration has obvious scalariform distribution in the oxidation ditch, therefore has denitrification functions preferably; Because the oxidation ditch process treatment effect is stable, effluent quality is good, so oxidation ditch process becomes the waste water treatment process of present main flow.
The 3rd class is continuous batch activated sludge process (Sequencing Batch Reactor Activated Sludge Process, SBR) and improve technology, carry out in the in fact tangible reactor of the entire treatment process of SBR technology, comprise into water phase, reaction period, precipitation phase, draining spoil disposal phase and lay-up period.The sbr reactor device belongs to complete ideal plug-flow reactor in time, classical sbr reactor device does not have the disturbance of water inlet in precipitation process, be ideal precipitation state, and the sbr reactor device has utilized " principle of selectivity " in the activated sludge bulking theory can prevent sludge bulking.
Yet through the sewage that said apparatus and art breading are crossed, its effluent characteristics is relatively poor, and that promptly CODcr concentration can not effectively reduce, colourity reduces is not enough, clearance is not high.
[utility model content]
The utility model provides a kind of immersion flat sheet membrane aerobe reactor that improves effluent characteristics.
The technical scheme that the utility model adopted is: a kind of immersion flat sheet membrane aerobe reactor, comprise aerating system and membrane module, described aerating system places reactor bottom, described membrane module comprises the membrane support of pair of opposing and the film that places each membrane support lower end, described membrane module is divided into activated sludge reaction district and film reaction district with reactor, described activated sludge reaction district is the zone between membrane module and the sidewall of reactor, and membrane reactor is the zone between a pair of membrane module.
As preferred embodiment of the present utility model, described aerating system crosses activated sludge reaction district and film reaction district.
As preferred embodiment of the present utility model, the film surface attachment of described membrane module has fine and close microbial film.
The utility model immersion flat sheet membrane aerobe reactor has the following advantages at least: by the waste water that the utility model reactor for treatment is crossed, COD
CrClearance reaches more than 85%, and colourity reduces by 60%, and effluent quality significantly improves.
[description of drawings]
Fig. 1 is the structural representation of the utility model immersion flat sheet membrane aerobe reactor;
The label among the figure and the corresponding relation of element are as follows:
| 1 | Aerating system | 3 | |
31 | Membrane support | 33 | Film |
| A | The activated sludge reaction district | ?B | The film reaction district |
[embodiment]
See also shown in Figure 1, the utility model immersion flat sheet membrane aerobe reactor structure that is square, comprise the aerating system 1 that is arranged at reactor bottom, and reactor is divided into the membrane module 3 of activated sludge reaction district A and film reaction district B and inlet channel and outlet conduit.
Membrane module 3 comprises a pair of membrane support 31 and places the film 33 of each membrane support 31 bottom, wherein, membrane support 31 is slim-lined construction and a pair of membrane support 31 is oppositely arranged, described film reaction district B is the zone between a pair of membrane module 3, and activated sludge reaction district A is the zone between membrane support 31 and the sidewall of reactor.
Aerating system 1 places reactor bottom, crosses activated sludge reaction district A and film reaction district B.
The waste water that needs to handle is entered in the activated sludge reaction district A of reactor through the peristaltic pump suction by water tank, active sludge adsorbs, degrades the organic pollutant in the waste water, afterwards, enter film reaction district B, by fine and close microbial film pollutants in waste water is further degraded attached to the film surface, at last, discharge through the water outlet suction pump.
The waste water of pulping and paper-making before entering the utility model reactor, chemical oxygen demand cod
CrConcentration about 1200mg/L, colourity about 200 times, suspended solid SS about 400mg/L, through after the utility model reactor for treatment, the chemical oxygen demand cod of the water that comes out
CrConcentration is about 150mg/L, colourity about 80 times, suspended solid SS about 50mg/L, its COD
Cr, colourity, SS clearance is respectively 85%, 60%, more than 85%, reached paper waste discharging new standard (GB3544-2008) substantially; In addition, hydraulic detention time is less than 24h, and sludge retention time is long, and excess sludge production is little.
As known from the above, the utility model immersion plate membrane bioreactor can reach the purpose of handling papermaking midcourse wastewater efficiently, and effect is undesirable when having solved art methods and handling this waste water, the problem of water outlet poor effect.
The above only is a kind of embodiment of the present utility model, it or not whole or unique embodiment, the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model specification sheets is claim of the present utility model and contains.
