针对某些海岛山塘水库含盐量不断变化的水质特点,开发超滤和反渗透联用的海岛淡水净化/咸水淡化一体化装置。结果表明,对于电导率约580μS.cm-1,浊度约20 NTU,CODMn约5.9 mg.L-1的原水,当超滤和反渗透产水比为1:1时,超滤产水电导率基本不变,浊度约0.1 NTU,CODMn降低约40%,混合产水电导率接近于原水的一半,浊度约0.04 NTU,CODMn约1.7 mg.L-1。此外,无论原水电导率如何变化,均可通过调节产水比使最终产水达到生活饮用水卫生标准。介绍了工艺流程、运行情况,并对运行数据进行分析。
In view of the changing water quality of Shantang Reservoir in some islands, an integrated island freshwater desalination / desalination unit combining ultrafiltration and reverse osmosis was developed. The results showed that for the conductivity of about 580μS.cm-1, the turbidity of about 20 NTU, CODMn about 5.9 mg.L-1 of raw water, when the ultrafiltration and reverse osmosis water ratio is 1: 1, ultrafiltration water conductivity The turbidity was about 0.1 NTU and the CODMn was reduced by about 40%. The conductivity of mixed water was close to half that of raw water, the turbidity was about 0.04 NTU and the CODMn was about 1.7 mg.L-1. In addition, no matter how the conductivity of the raw water changes, the water production ratio can be adjusted so that the final product water can reach the drinking water standard. Described the process, operation, and operating data analysis.
