AB  - After precision filtration ultrafiltration pretreatment of Jinhai lake water, the pretreated water is pumped into the desalination system equipped with different numbers of nanofiltration membranes by high-pressure pump (crn3-29, Grundfos, China). The nanofiltration membrane adopts commercial polyamide 4040 roll membrane module (vnf2, Guiyang times Wharton Co., Ltd.). After the pressure and flow rate are stable for half an hour, record the salt content data of produced water and calculate the desalination rate. The operating pressure is 1.3mpa, the salt content of influent is 7.5g/l, the water temperature is 30 ± 2 ℃, the influent flow is 2m3 / h, and the number of membrane modules is 6-8. The measurement is accurate to two decimal places. The desalination rate of nanofiltration system is higher than 80%, which meets the assessment index of the assignment. This data set is mainly applied to the study of brackish water desalination.
