芬兰清洁技术委员会的数据表明,20世纪70年代,芬兰造纸行业生产1t纸浆消耗250m3水;而今天,根据浆种不同,生产1t纸浆仅消耗10~40m3水,并且水的循环利用次数最高可达15次。世界著名的水化学企业芬兰凯米拉公司普通化学研发部副总裁KajJansson先生说:“环保立法是促进造纸业提升水资源利用率的原因之一,日渐高昂的水价也是一个重要原因。水价自上世纪80年代以来不断攀升。未来水资源将成为纸业具有战略性意义的原料。纸业提高水资源利用率不仅符合法规的要求,还可以降低工厂运营成本。”
Finnish Cleantech Committee data show that in the 1970s, the Finnish paper industry produced 1 ton of pulp to consume 250 m3 of water; today, depending on the type of pulp, only 1 to 4 m3 of water are consumed to produce 1 ton of pulp and the maximum number of recycle 15 times. Kaj Jansson, vice president of R & D at Kemira, Finland, a world-renowned water chemical company, said: “Environmental legislation is one of the reasons for promoting the utilization of water resources in the paper industry. The rising price of water is also an important reason. Since the 1980s, water resources have been rising steadily, and in the future, water resources will become a strategic raw material for the paper industry. Improving the utilization of water resources in the paper industry not only meets regulatory requirements but also reduces the operating costs of the factories. ”
