What the utility model will solve is to have now possibly cause secondary pollution or membrane module to clean halfway technical problem to the back flushing of ultrafiltration system cycle; A kind of simple and practical device that prevents the pollution of ultrafiltration backwashing water is provided; With decelerating membrane pollution, prolong the work-ing life of film.
In order to solve the problems of the technologies described above, the device of the utility model is achieved through following technical scheme:
A kind of device that prevents that the ultrafiltration backwashing water from polluting; Comprise hyperfiltration membrane assembly; The ultrafiltration of said hyperfiltration membrane assembly is produced the mouth of a river and is connected with ultrafiltration product water tank through membrane module output water lines; Said ultrafiltration is produced water tank and is connected with backwashing pump, and said backwashing pump produces the mouth of a river through the ultrafiltration that counter-flushing pipeline is connected to said hyperfiltration membrane assembly, is provided with strainer between the said counter-flushing pipeline of said backwashing pump and said hyperfiltration membrane assembly.
The pore size filter of said strainer is in the scope of 200～500 μ m.
Said strainer is y-type filter, T type filter, lamination strainer, brush type filter, flexible filter or self-cleaning filter.
The beneficial effect of the utility model is:
The automatic control degree of the utility model is high, adopts the potentially contaminated material in the strainer interception backwashing water, and the ultrafiltration backwashing water has been carried out anti-pollution processing, can effectively guarantee the spatter property of backwashing water, has improved developing result; Prevent that pollution substance from getting into the water purification side of film, avoids the irreversible damage of film; Can slow down the pollution of film, prolong the work-ing life of film, reduce running cost.
