摘要
通过冷冻法从DSD酸氧化废水中提取硫酸钠,解决了污水中含盐量高的问题;提取的硫酸钠可回用至盐析岗位,冷析后的废水可回用至氧化岗位,既取得了明显的经济效益,又符合清洁生产的要求。
Sodium sulfate is extracted from DSD oxidation wastewater by freezing,solve the problem of high salt content.Extraction of sodium sulfate can be reused to salting section,wastewater can reuse to the oxidation section,which has made significant economic benefits,but also comply with the requirements of clean production.
