AB  - After precision filtration ultrafiltration pretreatment, the water of Jinhai lake is desalted by reverse osmosis / nanofiltration system. The water yield and water recovery of the desalination system under different mixed loading modes and different operating pressures are mainly investigated. After the pressure and flow rate are stable for half an hour, record the water production of the desalination system and calculate the water recovery rate. The desalination membrane adopts commercial polyamide 4040 roll type nanofiltration and reverse osmosis membrane components (vnf2 and ulp100, Guiyang times Wharton Co., Ltd.). The operating pressure is 1.3-1.8mpa, 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 mixed membrane modules is 6-8. The measurement accuracy is taken to two decimal places. The fresh water output of the desalination system is greater than 1.2m3/h, and the water recovery rate is higher than 60%, reaching the assessment index of the assignment. This data set is mainly applied to the study of brackish water desalination.
