摘要

针对神华亿利能源有限责任公司工业废水的水质特点

采用石灰处理与高效反渗透技术相结合的处理工艺对其进行处理

并将处理水用于辅机冷却系统的补水及锅炉补给水。实际运行表明

高效反渗透回收率为90%

较普通反渗透高出15%

处理水质可达到回用标准

剩余10%反渗透浓水用于灰渣调湿

实现了废水零排放。该工艺使发电水耗降低了0.21kg/(kW·h)

每年可节约成本825.9万元

具有良好的经济效益。

Abstract

Against the features of industrial waste water in Shenhua Yili Energy Co.

Ltd.

the lime treatment combined with high efficient reverse osmosis technology was employed.The treated water was used for replenishment water of the auxiliary cooling system and the feed water.The process equipment system was introduced and operation economic analysis was conducted.The system operation showed that

the recovery rate of high efficient reverse osmosis was 90%

about 15% higher than that of the ordinary reverse osmosis

which can maximize the recovery of industrial waste water

making the water quality reach the requirement of reuse.Furthermore

the remaining 10%reverse osmosis water with high salt content was used for wetting the slag

which helped realizing the zero emission of waste water.Meanwhile

water consumption for power generation was decreased by 0.21kg/(kW·h)

and the cost can be saved by 8.259×106 yuan every year.
