Ultrafiltration is one of the membrane separation techniques using pressure as the driving force. The pore diameter of the membrane is between 20 and 1000A DEG for the purpose of separating macromolecules from small molecules. The hollow fiber ultrafilter (membrane) has the advantages of high filling density in a unit container, small occupied area and the like.
In the ultrafiltration process, the aqueous solution flows through the membrane surface under the push of pressure, the solvent (water) and the small-molecule solute permeable membrane which are smaller than the membrane pores become purified liquid (filtrate), and the solute and solute groups which are larger than the membrane pores are intercepted and discharged with the water flow to become concentrated liquid. The ultrafiltration process is dynamic filtration and the separation is accomplished in a flow regime. The solute is only deposited limitedly on the membrane surface, the ultrafiltration rate is attenuated to a certain extent to be balanced, and can be recovered by washing.
In the prior art, when a single-set ultrafiltration system is used for backwashing, only one water inlet pipe of a backwashing water inlet valve is used, and the ultrafiltration is subjected to upper backwashing and lower backwashing simultaneously. Backwashing has the problems of incomplete cleaning, long backwashing time, large backwashing discharge and the like, and influences the chemical water production efficiency, so that an ultrafiltration system needs to be optimized, and the overall water production efficiency of chemical water is improved.
