Analysis of input-output model for industrial water consumption in Beijing;

Based on the conception of rational volume of ecological water consumption,the total water consumption of Beijing City was divided into industrial water consumption,agricultural water consumption,domestic water consumption,tertiary industrial water consumption,and eco-environmental water consumption,and the benefits of water consumption of different parts were calculated.

The polymer iron sulfate has been used to handle industrial water and waste water in Hefei Iron &Steel Group Co.

Large circulation current state of industrial water of Nanshan Mine of Maanshan Iron & Steel Group is analyzed.

According to the investigation on the quantity of industrial water and wastewater drainage in part of the iron and steel complex, the repeat utilization ratio of industrial water is on the low side, but then it has ample potentialities in saving water, so it is of great immediate significance to unfold the work of water saving and sewage treatment in the iron and steel complex.

Energy saving transformation of industry water supplies system in the smelter;
