摘要
本文探讨了利用化学方法处理实验室中含铜污水和含铬污水。对于含铜污水,调节溶液的pH值,利用生成沉淀去除水中铜;对于含铬(Ⅵ)污水,首先使其还原为Cr3+,再调节溶液的pH值,利用生成沉淀去除水中铬(Ⅵ)。
This paper discusses to use chemical method to deal with wastewater containing copper and chromium. For the copper wastewater, adjusting the pH of solution, using the precipitation remove the copper; for chromium （Ⅵ） wastewater, firstly making it restore to Cr3＋, and then adjusting the pH of solution, using the precipitation to remove the chromium （Ⅵ）.
