株洲硬质合金厂于2000年1-11月的工业水重复使用率达到77.98％,优于国内有色行业7.98个百分点,接近新建企业标准。 该厂是一个以钨、钼、钴、铌等稀有金属冶炼加工为主的老企业,年工业用水量近2000万t。按行业标准,老企业的工业用水重复使用率为70％,新建企业为80％,因此,该厂把提高工业水的重复使用率纳入到企业的生产经营决策议程。凡是技改项目,都要把水的重复使用进行同步规划设计,“八五”技改项目之一的大制品生产线投产后,水复用率高达90％以上。
Zhuzhou Carbide Plant in January-November 2000 industrial water recycling rate reached 77.98%, better than the domestic non-ferrous industry 7.98 percentage points, close to the new business standards. The plant is an old enterprise mainly engaged in smelting and processing of rare metals such as tungsten, molybdenum, cobalt and niobium. The annual industrial water consumption is nearly 20 million tons. According to the industry standard, the reuse rate of industrial water in old enterprises is 70% and that of newly established enterprises is 80%. Therefore, the factory includes the reuse rate of industrial water into the decision-making process of production and operation of enterprises. All technological transformation projects should carry out the synchronous planning and design of the repeated use of water. After the large-scale production line of one of the “Eighth Five-Year” technological transformation projects is put into operation, the water reuse rate will reach over 90%.
