The flat sheet membrane assemblies comprise flat sheet membranes, a stainless steel membrane box and a stainless steel aeration box, wherein the stainless steel membrane box is arranged on the flat sheet membrane assemblies, a group of flat sheet membranes which are the same in size are evenly distributed in the stainless steel membrane box and evenly distributed in the stainless steel membrane box; the stainless steel aeration box is arranged on the flat sheet membrane assemblies, an aeration pipe is designed at the bottom of the stainless steel aeration box, and the aeration pipe is connected with an air blower. The membrane bioreactor is not apt to be polluted by sludge and can operate stably for a long time when used for treating sewage.
Description
Technical field
The utility model relates to a kind of water treatment device, is specifically related to a kind of membrane bioreactor.
Background technology
Membrane bioreactor (MBR) technology has been widely used in municipal wastewater and multiple organic industrial sewage is processed, it combines the advantage of traditional biological treatment technology and membrane separation technique, take full advantage of ultra-filtration membrane to the effectively catching of microorganism, can effectively resist the impact that organic loading, difference variation cause, the assurance system reliably and with long-term, stable operation.
The membrane Bio-reactor Technology development research use early stage, polysilicon section waste water treatment process is generally all continued to use conventional physical dosing, filtration, comprises NaOH, PAC, PAM dosing, ultrafiltration membrance filter, cleaner filtration etc.; Continue to use traditional activated sludge process at biochemical technology, polysilicon waste water inorganic components is complicated, and the organism difficult degradation causes traditional activated sludge process microorganism culturing difficulty large, easily runs off.Above-mentioned physics, biological method technology cause the sewage quality can't be up to standard, exist simultaneously the high system of working cost unstable, and the operational management difficulty is large.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the contamination resistance of membrane bioreactor that overcomes prior art is poor, the weakness that operation stability is poor, and the utility model provides a kind of contamination resistance stronger membrane bioreactor.
Technical scheme: for solving the problems of the technologies described above, the utility model provides a kind of membrane bioreactor, comprise reaction tank body and the one group of plate film assembly that is arranged in the reaction tank body, described plate film assembly comprises flat sheet membrane, stainless steel membrane case and stainless steel aeration case, wherein the stainless steel membrane case is arranged on the plate film assembly, and stainless steel membrane case inside is evenly arranged one group of identical flat sheet membrane of size, flat sheet membrane according to the uniform layout of a determining deviation in the stainless steel membrane case; Stainless steel aeration case is arranged on the plate film assembly, and stainless steel aeration case bottom design has aeration tube, and aeration tube is connected with gas blower.
The surfacing of membrane bioreactor flat-plate special membrane element, layout between the flat sheet membrane is compacter, spacing 5 ~ 10mm, plate film assembly bottom aeration tube is by providing air pocket during operation, between flat sheet membrane, form gas-solid-liquid three phase mixtures, the film surface is formed shearing force and Hydrodynamic turbulence, make the active sludge particulate be difficult to accumulate in the flat sheet membrane surface, make face be difficult for being polluted by mud, equipment can be for a long time, stably operation, and the activated sludge concentration of mixed solution can reach 8000-10000mg/L, has further reduced the sludge disposal amount.
Described flat sheet membrane is the double folding flat sheet membrane, and the spacing of double folding flat sheet membrane in the stainless steel membrane case is 5 ~ 10mm; Aperture on the described flat sheet membrane, its nominal diameter are 0.05 ~ 0.4 μ m; In the described reaction tank sludge circulation pump is installed; Suction tube in the reaction tank is connected with the water outlet vacuum primingpump.
Beneficial effect: the membrane bioreactor that the utility model provides, have stronger contamination resistance, can guarantee effectively that membrane bioreactor moves reliably and with long-term.
