摘要
制革废水有机物浓度高,含硫、铬等有害离子,是一种较难处理的轻工业废水,一般采用物化—生化组合工艺处理。本文分析了制革废水处理工艺选择中应着重考虑的因素,并对国内常用的处理工艺进行总结。
Tannery wastewater was a kind of light industry wastewater that is difficult to deal with, due to the highly organic concentration and the content of hazardous substances as sulfide and chromium ion. Tannery wastewater was treated generally by physico-chemical and biological combination technologies. The important aspects considered in selecting treating methods were analyzed in this paper, and the widely used processes in treating this kind of wastewater in China were also summarized.
