反渗透系统的通量均衡工艺与元件位置优化

摘要

This paper has analyzed the discrete of RO(reverse osmosis) membrane elements in terms of three testing indicators,proposed a concept about optimization of elements with different testing indicator installation positions in system process,described Total Differentiation (TD) mathematical model,defined effectiveness of TD on flux balance,verified the stability of TD optimization plan under condition of different operating parameters,such as feed temperature,advanced the fourth flux balance technology about element installation position.%分析了反渗透膜元件3项测试指标的离散性,给出了系统流程中不同测试指标膜元件安装位置优化的概念,描述了膜元件位置优化的全微分计算方法,明确了全微分法元件位置优化对于均衡系统通量的有效性,验证了全微分法元件位置优化方案对于给水温度等运行参数变化的稳定性.提出了元件位置优化构成了系统通量均衡第四大工艺的观点.
