摘要

以城市污水处理厂达标排放的中水为源水

采用双膜法和电去离子(EDI)技术处理中水

即经过混凝澄清——超滤——两级反渗透——电去离子处理后

经过试验验证

产水水质达到热电厂锅炉给水的水质要求

满足了电厂对中水回收再利用的要求。对超滤、一级反渗透、二级反渗透、电去离子进行了各种工况的影响试验

试验表明各级工艺均达到了所要求的结果。

Abstract

Using the standard effluent intermediary water from sawage treatment plant in the city as the source of raw water

through treatment process as in the following:coagulation purification + ultra-filtering(UF) + two-stage reverse osmosis(RO) + electro-deionization(EDI)

the quality of produced water reaches the requirements of feed-water quality for boilers in thermal power plants

satisfying the requirement of recycling utilization for intermediary water in thermal power plants.Test under influence of different operating conditions on UF

first-stage RO

second-stage RO

and EDI have been carried out

tests show that the technological process in each stage all reaches the required effectiveness.
