Nanofiltration host: nanofiltration is a green water treatment technology, is the latest development of international membrane separation technology, and can replace the traditional water purification method with high cost and complicated process in certain aspects. The nanofiltration can intercept organic matters with molecular weight more than 200 and multivalent ions, and allows small molecular organic matters and monovalent ions to permeate, so that elements beneficial to human bodies in water are reserved while the water is purified. The nanofiltration membrane can be operated under severe conditions such as high temperature, acid, alkali and the like, the condition range of membrane tolerance is wide, pollution resistance is realized, the operation pressure is low, the membrane flux is high, the operation cost of the device is low, and the energy consumption is extremely low. The nanofiltration main machine has complex scale formation and is mainly composed of nanofiltration membrane elements, membrane shells, meters, pipelines, valves, control boxes, an electrical control system, a rack and the like. According to the raw water quality and the water outlet requirement, the element retaining effect is considered, and the element retaining effect is different from the element retaining effect of the nanofiltration membrane customized by membrane manufacturers, and the aperture, the self-charged condition and other factors of the different nanofiltration membranes are different to a certain extent, so that the removal difference exists between the membranes. The nanofiltration membrane is a functional semipermeable membrane which allows solvent molecules or low-valence ions to permeate and entraps high-valence ions, and has the functions of removing soluble salts, colloids, organic matters and microorganisms in water, reducing most of hardness and retaining beneficial substances and microelements in groundwater.

The water quality characteristics of the effluent of the SM, BM, H70, SL and BL five nanofiltration membranes are different, wherein the desalination rates of the SM, BM and H70 membranes are close, and the desalination rates of the SL and BL two membranes are relatively low.

The three membranes SM, BM and H70 have ideal removal effect, the overall removal rate SM is more than BM and more than H70, and the water quality of the three membranes is better. The total hardness is below 85 mg/L, and no scale is found after boiling water. The contents of sulfate, chloride and nitrate are greatly reduced. In addition, the three films have close metasilicic acid retaining ability and can retain 80% of metasilicic acid.

BL and SL are slightly weaker in relative removal effect, and other indexes except the higher removal rate of sulfate have no obvious removal effect. The total hardness of BL and SL effluent is 160 mg/L and 260 mg/L respectively, and obvious scale can be observed after the SL effluent is boiled. The nitrate removal rate of BL is only 16.77%, and the nitrate content of the effluent is 12.19 mg/L; SL has substantially no nitrate removal effect.

Different nanofiltration membranes have larger difference in removal rate, and matched nanofiltration membranes can be selected according to the quality of raw water.

The foregoing description is only of the preferred embodiments of the utility model and is not intended to limit the utility model.
