反渗透工艺处理电厂循环冷却排污水

RO process treating blowdown from circulating cooling water system of power plant

针对电厂循环冷却排污水浊度高 ,含盐量高的水质特点 ,采用反渗透工艺进行处理 ,出水含盐量小于 2 0mg/L ,满足锅炉预脱盐补充水的要求。介绍了反渗透工艺及其预处理工艺 。

The blowdown from the circulating cooling water system of power plant is high of salinity and turbidity. RO (reverse osmosis) process is very successful treating this kind of wastewater with residual salinity less than 20 mg/L in the output water. It will be enough to use for boiler water make-up as demineralized water. The RO process, pre-treatment, operating expenses and problems are described.
