摘要
作者对磷化废水的处理技术进行了实验研究 ,提出以二次氧化法降低CODCr值 ,以石灰乳脱除磷、锌等污染物的处理工艺。结果表明 ,采用该方案处理磷化废水 ,具有方法简单 ,净化效率高 ,经济实用等特点。最后排放的污水完全符合国家综合污水排放标准。
The paper discusses the treatment of wastewater from bonderizing process by experiments and proposes a way of decreasing COD Cr by oxidation for twice and the removal of Zn, P by slaked lime. The results accordes with the demands of GB8978-1988 and indicates that it is a simple, effective and economical way.
