摘要

依据浊度法原理提出一种用于测定反渗透进水结垢临界点的试验装置

利用该装置对某电厂反渗透处理回用循环水排污水进行结垢风险评估

同时对另一电厂立项研制的5种国产反渗透阻垢剂进行性能评价。结果表明:浊度法可快速准确测定反渗透进水的结垢临界点

确定反渗透进水的结垢倾向

便于电厂及时调整水处理工艺条件;浊度法也可用于快速评估反渗透阻垢剂的阻垢性能

为反渗透阻垢剂的选型提供依据。

Abstract

A test device for determining the scaling critical point of reverse osmosis inlet water is proposed based on turbidimetric method. By using this device

the scaling risk of circulating sewage treated and reused by reverse osmosis in a power plant is evaluated. The performance of five domestically produced reverse osmosis scale inhibitors developed by another power plant project is evaluated. The results show that

the turbidimetric method can quickly and accurately determine scaling critical point and scaling tendency of reverse osmosis inlet water

which is convenient for power plants to adjust the water treatment process conditions timely. The turbidimetric method can also be used to quickly evaluate the scale inhibition performance of reverse osmosis scale inhibitors

and provide a basis for the selection of reverse osmosis scale inhibitors.
