化学改性二氧化锰生产废液中有效成份的回收

Recovery of the Effective Components in the Waste Liquor of Chemically Modified MnO_2 Production

用配合滴定法对化学改性二氧化锰生产过程中的废液有效成份进行了分析，讨论了有效成份的回收方法及其经济效益．结果表明，对改性二氧化锰生产废液中有效成份的回收，不仅可以降低成本，而且有利于环境保护．

The effective components in the waste liquor of chemically modified MnO_2 are analyzed by means of complex titration method. The recovery methods for the effective components and their economic benefits are also discussed in the paper. The results show that it not only can reduce the production cost, but also is of great advantage to environmental protection to chemically modified MnO_2 production.
