Description
Technical field
The utility model is the improvement with membrane support plate in flat membrane component to water treatment, relates in particular to a kind of thin thickness and is difficult for
Distortion, and filter running resistance and the little flat membrane component of transmembrane pressure.
Use gripper shoe.
Background technology
Film-bioreactor (Membrane Bioreactor, MBR), as the new and effective sewage disposal skill of one
Art, has become the selection of a kind of very attractive and competitiveness of municipal sewage and Industrial Wastewater Treatment and reuse, and is regarded as " best practical technology (Best Available Technology) ".Flat membrane component is the core parts of MBR reactor, and gripper shoe is the important core parts of flat membrane component, the gripper shoe of support plate film is as described in Chinese patent CN1676202, CN101541406, CN201534787U, CN201493055U, CN201692771U etc., basic employing rotproofness is good but the sheet plastic of rigidity relative mistake has longitudinal water conservancy diversion groove (conventional longitudinally alternate staggering) at its positive and negative; Assembly assembling be membrane component by the alternate U type in width both sides slot on frame support, the flat membrane component that two sides is covered with to flat sheet membrane composition is inserted downwards in each U type groove by top, diaphragm gripper shoe is alternate fixing, is to insert U type groove location by dual-side.Flat membrane component since utility model, supporting plate structure and form alternate location and be substantially not always the case, other forms never again, assembling mode is also unique is the downward plug-in type in top.And in Practical Project for having made enough filter areas, meet large filtration flux demand, membrane component all adopts large scale as far as possible, for example having compared with regular size is the large plane of high by 1.8 × wide 0.5 meter, and area is the bigger the better in theory, but in water, filtered out water resistance and gripper shoe strength and stiffness owing to inserting, insert the restrictions such as formula assembling, this size has been general full-size.For so large plane, for being inserted water pressure in effectively preventing from using and below aeration scouring force effect is out of shape, plastic support plate thickness is conventionally at least at 5.5-6.0mm, and area increases the proportional increase of thickness.This gripper shoe has the following disadvantages in actual use: the one, and relatively thick gripper shoe (5.5-6.0mm), become membrane component and form the second largest factor of cost, its cost accounts for 40-50% of full wafer membrane component, also be to cause that membrane component cost is higher, the reason that can not ignore of Difficulty, can cause again rigidity inadequate but reduce plate thickness, not enough so that it erects support maintenance plane; The 2nd, large planar film element is to keep element to require spacing (being generally 7-8mm) by side location (inserting U type groove), for large plane like this, even so thick plastic support board, only depend on dual-side location, unavoidably can deform and warp in actual use, distortion warps and causes spacing between adjacent two membrane components to change at the position that warps, particularly pitch smaller can cause air water between membrane component to wash away inhomogeneous, produce deposition, and then cause face to stop up, effluent flux is declined.Although
Can overcome the distortion shortcoming that warps by increasing gripper shoe thickness in theory, but to form cost higher because it accounts for, thicken that can to cause cost to increase more, more affect applying of membrane bioreactor; Secondly, gripper shoe thickness increases, and also will reduce effective filtration area (minimizing of same components thickness sheet number) in unit volume, and weight increases.Although therefore in use yielding warping of existing gripper shoe, comprehensive each factor practical application thickness is still in the majority with 5.5-6.0mm, and therefore above-mentioned shortcoming becomes and is difficult to overcome.It is high that flat membrane component supports thickness of slab cost, and yielding warping still in using, and become immersed type flat plate membrane component and used the obstacle that is difficult to go beyond.
Secondly, existing vertically much larger than the rectangle gripper shoe of width, filter water outlet and mostly adopt longitudinal water conservancy diversion between single-phase
Groove is guided to top (top or side, top) water outlet, i.e. single upper water-out.But up to the membrane component of 1.8 meters of left and right (large area is even higher), be immersed in water on plate face downforce objectively different, cause upper and lower transmembrane pressure difference large, guide to top delivery port discharge for diaphragm bottom being seen through to face water outlet, operation must adopt pump suction water outlet, substantially can not adopt the operation of gravity pressure reduction, be a factor that causes operation energy consumption high.Even if adopt suction draining, due to the differential water pressures reason such as not, the upper and lower region of face suction force is objective can not be evenly, the upper and lower each point suction force of plane is inhomogeneous, very easily causes film surface pollution degree varies, for example, near the large region of delivery port suction force, film surface pollution is serious, relatively light away from pumping out mouth of a river film surface pollution, long-play makes the each region of face resistance inhomogeneous, also can shorten diaphragm service life.When the online Chemical cleaning of single delivery port, because of residual filtered water in gripper shoe lower guide chute, clean when chemical agent enters membrane component inside and can be diluted, cause actual cleaning liquid inhomogeneous in face CONCENTRATION DISTRIBUTION, sometimes even can not arrive all faces, cause online Chemical cleaning not thoroughly, not comprehensive, not only affect cleaning performance, and repeatedly clean for a long time thoroughly region and pollute infiltration and finally can not clean, film contamination resistance is declined, process water outlet and also decline; Besides, exist and filter remaining water in membrane component, top perfusion solution infiltration bottom face consumption is large, causes cleaning liquid waste, has increased film on-line cleaning expense.
Be that CN 102512963 B disclose a kind of flat membrane component gripper shoe and flat membrane component and plate film assembly for the problems referred to above China Patent Publication No., exceed gripper shoe face boss by being respectively provided with some distributions at membrane component gripper shoe tow sides.This kind of technical scheme relies on gripper shoe face boss to support as interval by adjacent membranes elements combination, effectively make the gripper shoe distortion that can not warp, guarantee that the each dot spacing of adjacent membranes element interplanar is constant, aeration washes away evenly, reduce film pollution, and obvious attenuate gripper shoe thickness, thick is 3.5mm left and right by original 5.5-6.0mm attenuate, make gripper shoe weight and cost 30% left and right, but this kind of technical scheme need to be carried out perforate processing to the film depending on thereon, and boss place film is carried out to effective sealing, not so easily cause and process water or clean liquid because of the short stream of opening, make film ineffective, although and do not recycle U-shaped slot between its gripper shoe and carry out plug-in mounting, but it utilizes assembling through hole or groove, carry out press seal by securing member serial connections such as bolts, its side seal has to be strengthened, said as description, it must use sealing joint strip to seal or utilize side seal board to seal, the problems referred to above still have much room for improvement.
