Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to an ultrafiltration membrane integrated water purification equipment. Background Art

[0002] Ultrafiltration membrane equipment is a membrane separation technology that can purify and separate solutions. It is a solution separation device that uses ultrafiltration membrane fibers as filtration media and the pressure difference on both sides of the membrane as the driving force. The ultrafiltration membrane only allows water molecules, inorganic salts and small molecular organic matter in the solution to pass through, while intercepting large molecules such as suspended matter, colloids, proteins and microorganisms in the solution, thereby achieving the purpose of purification or separation.

[0003] In the actual implementation of small-scale centralized drinking water purification and renovation projects, it was found that the on-site installation conditions and operating conditions in this type of engineering projects in various regions across the country are complex and diverse. The existing equipment room height and size make it impossible to place the entire set of water purification equipment inside the equipment room. The traditional immersed ultrafiltration membrane components cannot be smoothly maintained and replaced under the limited room height, and there is not enough available space outside, which ultimately affects the implementation of the project and equipment installation. Although some integrated water purification equipment composed of integrated ultrafiltration membrane filters has solved the above problems, since the raw water directly passes through the ultrafiltration membrane filter, or simply only a sewage interceptor is placed in front of the ultrafiltration membrane filter, when the raw water enters the ultrafiltration membrane filter, the larger granular impurities contained in the sewage will follow in at the same time, so that there will be more impurities remaining inside the ultrafiltration membrane filter, affecting the service life.
