  对于高矿化度矿井水的深度脱盐处理，需要采用反渗透（RO）膜法对矿井水中的硬度、盐度和其他多种低浓度污染物去除。由于反渗透系统对原水的水质要求较高，装置进水的淤塞密度指数SDI值需要<3，浊度<0.5。使用合适的预处理技术降低进水SDI值和浊度，可以防止反渗透膜表面机械损伤和降低污染，对后续的RNRR多级强化膜浓缩工艺的安全稳定运行是十分必要的。本文采用瓷砂过滤+大通量超滤预处理技术，通过物理截留作用对悬浮物/颗粒物、胶体、大分子有机物去除，以满足后续反渗透工艺深度处理的进水SDI和浊度要求。\n

    For the deep desalination treatment of high salinity mine water, it is necessary to use reverse osmosis (RO) membrane method to remove hardness, salinity, and other low concentration pollutants from the mine water. Due to the high water quality requirements of the reverse osmosis system, the SDI value of the sedimentation density index of the inlet water of the device needs to be<3 and the turbidity<0.5. Using appropriate pretreatment techniques to reduce the SDI value and turbidity of the influent can prevent mechanical damage to the surface of the reverse osmosis membrane and reduce pollution, which is essential for the safe and stable operation of the subsequent RNRR multi-stage enhanced membrane concentration process. This article adopts ceramic sand filtration+high flux ultrafiltration pretreatment technology to remove suspended/particulate matter, colloids, and large molecular organic matter through physical interception, in order to meet the SDI and turbidity requirements of subsequent deep treatment of reverse osmosis process.\n

\n

    This dataset was obtained using indoor experimental methods. The raw water was simulated high salinity mine water artificially prepared with tap water. The pretreatment device includes two parts: a porcelain sand filter column and an ultrafiltration device. The designed water volume is 0.5-1.0 m3/h, and the sand filter column is 1500 mm high with a diameter of 10 cm. The filtration flow direction is downward. Firstly, by comparing the physical and chemical properties and filtration performance of the three filter materials, the turbidity of the effluent and the change in the head loss of the filter column are obtained, which serve as the basis for selecting the porcelain sand filter material. The turbidity and head loss, as well as the optimal filtration rate data under different filter layer thicknesses, were obtained through experiments. The relationship between backwash strength, expansion rate, and flushing duration was also obtained, which serves as the basis for optimizing the operating parameters of the ceramic sand filter column. Secondly, by conducting ultrafiltration membrane operation experiments under different membrane fluxes, influent TDS concentrations, and temperature conditions, data on the changes in transmembrane pressure difference (TMP) during operation under different conditions were obtained, which served as the basis for optimizing the operating parameters of the ultrafiltration membrane. Finally, obtain the effluent turbidity and SDI value data under the conditions of simultaneous operation of porcelain sand filtration and ultrafiltration.\n

    The dataset contains a total of 11 sets of data, with each set containing 5-65 data points, and the dataset is fully open for sharing.
