在白银市郊区,有一座像白色山丘似的庞大堆积物,这是白银氟化盐有限公司多年来在生产氢氟酸时产生的工业废渣氟石膏。这些氟石膏长期堆积,造成严重污染,且每年以近十万吨的数量增加。正是这如山似的工业废渣,经处理后可作为各种硅酸盐水泥的缓凝剂、硫酸盐炉渣水泥和矿化剂,使水泥生产降低成本,效益十分可观。2000年以来,白银氟化盐有限公司积极为这些工业废渣找出路,将它们销往各大水泥厂,这座越长越大的“白山”将逐渐被吃掉,取代它的是巨大的经济效益和清洁的环境。在白银,无论是走进像银光化学工业公司这样的老企业,还是如红鹭粉体材料有限公司这样的高科技新型企业,抑或走进农家小院,处处都可寻到循环经济的足迹,感受到它的美好前景,循环经济已从发展理念变成了
On the outskirts of Silver City, there is a huge accumulation of white hills, the industrial wastewaste produced by Silver Fluoride Co. Ltd. over the years in the production of hydrofluoric acid. These fluorogypsum long-term accumulation, causing serious pollution, and the annual increase of nearly 100,000 tons. It is this mountain-like industrial waste, after treatment can be used as a variety of portland cement retarder, sulfate slag cement and mineralizer, cement production to reduce costs, the benefits are considerable. Since 2000, Silver Fluoride Co., Ltd. has actively found ways to dispose of these industrial waste residues and sell them to major cement factories. The larger and larger Baishan Mountain will gradually be eaten up instead of being huge Economic efficiency and clean environment. At Silver, whether it is going to an old enterprise like Yinuang Chemical Industry Company or a new high-tech enterprise such as Red Heron Powder Material Co., Ltd., or into the small courtyard of a peasant household, the footsteps of circular economy can be found everywhere, Feel the bright future of it, circular economy has changed from the concept of development into
