摘要
对合成草酸工艺钙化法与铅化法进行了比较讨论,用大量资料数据说明铅化法工艺中排放的大量含铅废水污染环境,含铅废水的处理难度较大,而钙化法可以从根本上解决含铅废水的排放问题,对于存在的产品质量问题是可以解决的。
The calcification process for synthetic of oxalic acid was compared to the lead involved process which produces huge amount of lead-contented wastewater. Substantial data have been collected to show that the lead-contented wastewater is very difficult to be treated and thus brings considerate pollution to the environment. This problem can be solved by using the calcification process instead of lead-process, and the product quality will be improved as well.
