摘　　要：本文以北方某钢铁企业为例,分析了该厂给排水系统存在的问题并提出节能改造建议。通过新建中水管道、浓盐水收集管网、生产废水截留设施和实施供水智能化控制,减轻了厂区污水处理厂运行负荷,改造后厂区废水处理站处理水量较之前降低50%,每年可节约废水处理成本1818万元。循环水系统补水通过采用新水与一级除盐水的勾兑水,循环水系统浓缩倍数由2~2.5提高到3.5~4。此外,浓盐水实现了零排放,吨钢取水量达到行业先进水平。Taking an iron and steel enterprise in northern China as an example,this paper analyzes the problems existing in the water supply and drainage system of the plant and puts forward some suggestions for energy saving reform.Through the construction of new reclaimed water pipeline,concentrated brine collection network,production waste water interception facilities and the implementation of intelligent water supply control,the operation load of the plant sewage treatment plant has been reduced,and the water treated by the plant wastewater treatment station after the transformation has been reduced by 50%compared with the previous,which can save 18.18 million yuan of wastewater treatment cost per year.The concentration ratio of circulating water system is increased from 2-2.5 to 3.5-4 by mixing new water with primary demineralized water.In addition,the concentrated brine has achieved zero emissions,and the water withdrawal per ton of steel has reached the advanced level of the industry.
