发展重金属产业必须抓好环境保护,应大力研究和推广应用无污染冶金工艺。 重金属产业带来 的环保问题 重有色金属在有色金属中有着重要的地位。20世纪中期,随着工业化的进程,有色金属工业规模越来越大。在相当长的时间里,人们只着眼于金属产量的增加,忽视了环保,由此而引发了环境污染问题。在一些工业发展较快的国家,环境污染事件频繁发生。 重有色金属产业给环境造成污染主要有以下三个方面:
The development of heavy metal industry must do a good job of environmental protection, should vigorously study and promote the use of pollution-free metallurgical processes. Environmental issues brought by heavy metals Heavy non-ferrous metals in non-ferrous metals has an important position. In the mid-20th century, with the industrialization process, the non-ferrous metal industry was getting larger and larger. For a long time, people only focus on the increase of metal output, ignoring the environmental protection, which led to environmental pollution problems. In some countries where industrial development is fast, environmental pollution incidents occur frequently. Heavy non-ferrous metal industry to the environment caused by pollution mainly in the following three aspects:
