Description
技术领域：
本发明涉及一种废水处理剂，尤其涉及一种机械加工清洗废水处理剂。
背景技术：
在机械加工生产过程中，需要使用清洗液对在机械加工过程中产生的废弃物料不断的进行清洗与处理，因此，在机械加工的过程中就会产生大量的机械加工清洗液废水，这种机械加工清洗所产生清洗液废水中含有大量的油污、油泥、表面活性剂、COD、CODCr、金属屑、固体杂质等污染物。如果将上述机械加工的清洗液废水直接排放，极易造成对环境的污染。
因此，如何来实现对机械加工清洗过程中产生清洗废水液经废水处理剂处理后进一步的回收再利用，实现了对环境状况友好的生产循环，及机械加工的绿色生产。
发明内容：
本发明提供一种机械加工清洗废水处理剂，其可对机械加工清洗废水所产生的废水有效处理，经处理后的废水其CODCr 的去除率可达95%以上，COD总去除率可达98%以上，处理剂用量少，废水处理速度快、综合使用成本低。

本发明所述助凝剂为由乙二胺与羟基乙叉二磷酸经有机合成后与葡萄糖酸钠复配而成。
本发明所述过碳酸盐为过碳酸钠和/或过碳酸钾，所述氯化铝为聚合氯化铝。
本发明所述硅酸铝铁为聚硅酸铝铁。
本发明所述助凝剂的制备是将乙二胺和羟基乙叉二磷酸按现有的生产方法进行有机合成得到产物后再与葡萄糖酸钠按任意比例复配制成，一般控制二者按质量比例为4：6-5：5之间。
本发明清洗废水处理剂对清洗废液处理方法是：先将废水进行酸碱中和、破乳，沉降等过程对清洗废水进行预处理以降低油污、油泥、表面活性剂、COD、金属屑、固体杂质等污染物； 再用本发明清洗废水处理剂通过“高效的物理-化学法”进一步与清洗废水发生物理化学综合反应后沉降； 最后再通过活性炭吸附。
本发明所述机械加工废水处理剂是一种复合型废水处理剂，对机械加工清洗后的清洗废水处理有良好效果，填补了国内机械加工行业清洗废水处理的空白，具有如下优点：
本发明本机械加工清洗废水处理剂是通过“物理、化学相结合的方法”对清洗废液进行处理，是一种综合处理剂，它具有优良的氧化-还原反应性能和凝聚、沉降高分子聚合物的功效，还能有效去除废水中的重金属离子。试验表明，经该清洗废水处理剂处理后的机械加工清洗废液， CODCr的去除率可达95%以上，COD总去除率可达98%以上；
本废水处理剂是以“多效复配技术原理”，并使用助凝剂“OT-SP”进行精心配方筛选得到的复合型处理剂，较单组份和少数几个组份复配的处理剂废水处理综合效果好；
本发明处理剂用量少，废水处理速度快、综合使用成本低。
