In the prior art, have the sewage-treatment plant of submerged membrane filter assemblies, adopt the doughnut membrane filtration module to come sewage is filtered.The doughnut membrane filtration module is made up of the hollow-fibre membrane silk, and the hollow-fibre membrane silk is easy to fracture, can cause the sewage disposal flux to descend, and causes the frequent replacing of doughnut membrane filtration module thus, and service life is short.Under the normal operation, the life-span of doughnut membrane filtration module is roughly 1 year, causes cost of sewage disposal very high, and the economic benefit that the sewage recovery obtains is difficult to balance each other with the cost of sewage disposal.Secondly, the sewage-treatment plant that the doughnut membrane filtration module constitutes adopts the compression type filter type, and the booster pump power that uses during filtration is big, and the energy consumption height causes filtering the operating cost height; And the treatment tank in the hollow-fibre membrane filtration processing equipment of compression type adopts hermetic type, complex structure, cost height mostly.
(3) summary of the invention
Sewage disposal device functional reliability at above-mentioned employing immersion doughnut membrane filtration module is relatively poor, construction and operating cost problem of higher, the applicant studies improvement, designs and provide that a kind of functional reliability height, operating cost are lower, the sewage-treatment plant that has the submerged membrane filter assemblies of good effect of separating solid from liquid.
The technical solution of the utility model is as follows:
The sewage-treatment plant that has membrane filtration module, it comprises treatment tank, device submerged membrane filter assemblies in the treatment tank, membrane filtration module is connected with pipe-line transportation system respectively, aerator also is installed and the device of air that looses in the treatment tank, it is characterized in that described membrane filtration module is made of the flat sheet membrane filter element, described flat sheet membrane filter element has a sealed framework, the flat filter membrane of both sides device of framework, delivery port is arranged on the framework, and described delivery port is connected with suction pump by pipeline.Described membrane filtration module comprises a plug-in mounting frame that has slot, and vertical insertion of flat sheet membrane filter element is installed in the slot of plug-in mounting frame.In treatment tank, can also place activated sludge in case of necessity.
Superior technique effect of the present utility model is: 1, membrane filtration module is made of the flat sheet membrane filter element, the flat sheet membrane surface area is big, be difficult for stained, stain resistance is strong, utilize the aeration shearing force to wash away the film surface, can keep higher water filtration flux, so do not need to increase back purge system, good effect of separating solid from liquid, functional reliability height and operating cost reduces; 2, above-mentioned membrane filtration module adopts the draw and insert-type structure to install by the flat sheet membrane filter element, and the displacement of monolithic membrane element is convenient, and maintenance cost is low; 3, under the normal operation, can reach about 5 years the service life of flat sheet membrane, and amortization charge is low; 4, there is delivery port each flat membrane component upper end, in the delivery port connecting pipe, adopts the mode of suction filtration, and it is low consume energy, can be have now the doughnut membrane filtration module operation energy consumption 1/10th; 5, owing to adopt the mode of water pump suction filtration, so treatment tank is opening, structure is simpler, and cost is lower; 6, according to the needs of water quality treatment, can also optionally add activated sludge, sewage is carried out biochemical treatment, enlarge range of application of the present utility model.
