摘要
针对含铬废水的分离处理,采用化学沉淀法中的亚硫酸钠还原,焦亚硫酸钠,氢氧化钠沉淀法,讨论了原液pH值、还原剂投放量等对处理含铬废水反应的影响。通过对比,总结出在不同反应条件下的优缺点,为今后实践运用提供了数据。
In this paper, chemical precipitation of sodium sulfite reduction, sodium pyroisulfite, and sodium hydroxide precipitation method has been used to treat wastewater contaminated with chromium, investigated the effect of pit value, mass of dose and compared the advantage and disadvantage with different state and provided the data for future.
