去除乳化液废水COD-硫酸亚铁和聚硅酸铝铁的方法技巧

作者:李木木 发布时间:2020-03-29 浏览次数:561

  随着机械制造、加工行业的发展导致各种乳化液在此行业得到不断的推广应用,乳化液主要成份为机油或矿化油、乳化剂、润滑防腐剂和水。在使用过程中产生了高浓度、乳化严重、成分复杂且波动大的乳化液废水,该废水中的乳化油非常稳定,不易破坏很难处理,COD含量高,若此废水的排放处理不当,会造成严重的环境污染。目前国内外对低浓度含油废水的处理进行了大量的研究工作,破乳是处理乳化液废水的关键问题,常用的破乳方法有加热、盐析法、凝聚法、超声破乳法、酸化法、混合法、化学絮凝浮上法和超滤法。综合分析以上方法,从工程实际出发,本研究主要采用凝聚法对高COD乳化液废水进行了絮凝条件的研究,为后续的工程提供可靠的应用数据。

  随着PAM投加量的增大,COD的去除率呈逐渐增大的趋势,***后趋于平稳的,当PAM投加量为0.8mL时COD去除率达到***大,为28.24%,所以0.2%PAM的***佳投加量为0.8mL。具体联系洛阳兆明环保设备更多相关技术文档。
