水合肼废盐水次氯酸钠氧化工艺探索

Exploration of the sodium hypochlorite oxidation process for the wastewater generated from the production of hydrazine hydrate

探索了水合肼废水的氧化工艺。着重介绍了次氯酸钠氧化过程中的工艺控制点的选择。开展了ORP控制性氧化的新工艺试验,给出工艺试验结果。用次氯酸钠氧化水合肼废盐水,可以得到TOC质量浓度250 mg/L左右的盐水,为进一步处理创造条件。

The oxidation process of hydrazine hydrate wastewater is explored.Emphasis was placed on the selection of process control points in the sodium hypochlorite oxidation.A new process experiment is conducted on oxidation control by oxidation-reduction potential.The experiment results of the new process is provided.Hydrazine hydrate wastewater is oxidized by sodium hypochlorite,yielding brine with a TOC mass concentration of around 250 mg/L and creating conditions for further treatment.
