摘要:

每台反渗透装置可生产除盐水60t/h,但需排出浓盐水20t/h。为了减少废水排放,对设备进行了改造,将1/2浓盐水回配到反渗透装置的给水中。改造后反渗透工艺运行稳定,出水指标达到国家标准,可节约地下水20t/h,达到了节能减排与环保增效的目的。

Abstract:

Each reverse osmosis device can generate 60t/h demineralized water,but it needs to discharge 20t/h concentrated brine. In order to reduce discharge quantity of waste water,the equipment is modified,so that half of the concentrated brine can return to the feeding water of the reverse osmosis device.With this improved reverse osmosis process,the plant is running stably,the discharged water meets national standard,and 20t/h ground water can be saved.It’s an energy-saving and emission-reduction,environmental friendly and efficient process.
