采用反渗透—混床系统进行锅炉补给水处理

介绍了反渗透－混床除盐系统处理锅炉补给水时的运行经验。经4年的实践表明：（1）采用机械搅拌澄清池和三级过滤的系统，可以达到反渗透组件对进水水质的要求；（2）反渗透组件的脱盐率每年的降低1％－2％，在设计中必须考虑；（3）一般情况下，反渗透装置的出水应经过除碳器再送入混床；（4）混床的出力必须有足够的余量，以免影响供水。

BOILER MAKE-UP WATER TREATMENT USING REVERSE OSMOSIS-MIXED BED SYSTEM

Operational experience of boiler make-up water treatment by using reverse osmosis-mixed bed demin-eralizing system has been described. Practice during the period of four years shows: (1) Settled water pond and three-stage filtration system with mechanical agitation can meet the requitments of reverse-osmosis components to the inlet water quality; (2) It must be considered in the design that the demineralization efficiency of reverse-osmosis components will be decreased about 1%～2% in every year; (3) In normal case, the outlet water from reverse-osmosis equipment shall enter into mixed bed via a decarbonator; (4) The output capacity of the mixed bed must have a sufficient surplus, to avoid its influence on the water supply.
