提高工业用水效率是促进我国节水防污型社会建设的重要举措。利用2011 年水利普查数据, 分析了河南省 工业用水结构和地区分布特征, 并以万元工业增加值用水量为指标计算了河南省各地市的工业用水效率, 分析了工 业用水效率地区分布平衡情况及差异原因, 最后有针对性地提出了四种情景下的工业节水目标, 计算了各地市工业 节水潜力。研究表明, 河南省工业用水效率主要取决于一般工业用水效率, 其次为高用水工业用水效率, 火核电业 用水效率影响较小; 全省工业节水潜力较大, 在7. 43 @ 108 ~ 13. 27 @ 108 m3 之间。

Impro ving indust rial water use eff iciency is an impor tant measure to promote the co nstr uctio n o f so ciety of w ater con2 serv atio n and po llution pr evention. Accor ding t o the w at er co nser vancy surv ey results in 2011, t he industr ial wat er use str uctur e and dist ribution in H enan Prov ince w ere ana lyzed. The industrial wat er use efficiencies o f 18 cit ies in H enan Pr ov ince wer e cal2 culated based on the index of water use per ten tho usand y uan of added industr ial v alue, w hich can ex plain the difference o f w a2 ter user efficiency among differ ent cities and its causes. Finally, four scenar ios of industrial wat er sav ing tar gets wer e pro po sed, and the water sav ing potential of each city w as calculated. The results show ed that indust rial w ater use efficiency depends pr i2 mar ily o n the g ener al industrial water use efficiency, follow ed by the hig h2w ater industr ial water use efficiency, and water use ef2 ficiency of thermal and nuclear power industr y has insignificant effect s o n the mean industr ial water use efficiency. I n addition, ther e is a lar ge industr ial water sav ing pot ential in H enan Pr ov ince, which reaches 7. 43@ 108 ~ 13. 27@ 108 m3
