冬季脱盐水站膜系统运行优化研究

摘要

The operation optimization of ultrafiltration-reverse osmosis double membrane system with low-temperature influent water in winter was studied. Through the comprehensive comparison between the costs of influent water warming and pressure increasing, and the operation condition of the system, the optimal operating mode was determined, which was: heating water to 13 - 15℃ and then, increasing the pressure, so as to ensure a stable running of the system and maintain a constant water production. Through the optimization, the energy consumption of the system was reduced under the premise that an effective water production had been guaranteed.%研究了超滤-反渗透的双膜系统在冬季低温进水条件下的运行优化,通过综合比较进水升温和系统提压的成本与运行情况,确定了系统最佳运行方式为加热进水至13～ 15℃后提压,保持恒定产水量运行,此种运行方式可在保证系统有效产水的前提下,节约能耗.
