线切割含油乳化废液处理方法的进一步研究
|
摘要
线切割含油乳化废液乳化稳定性高、COD_(Cr)值高、成分复杂、污染浓度高,采用单一的处理方法往往不能取得很好的处理效果,需要一种高效、便捷、低成本的处理方法来解决偏远地区,分散的小型作坊或工厂的此类废液的处理排放问题。
本课题对现有的工艺方法进行了优化与改进,力争使处理后废液的COD_(Cr)值和含油量得到进一步降低,达到使处理后废液可直接排放的目标。
通过前期探索实验,对微电解-絮凝-微电解-絮凝的四步处理方法进行了重复、验证分析与总结,省略了第一步微电解操作,采用絮凝-微电解-絮凝的三步法对废液进行了处理,对原四步处理后三步中的各影响因素的最佳点进行了重新验证与优化。在微电解处理中,调节了pH值,研究了pH值对微电解处理效果的影响并将反应时间延长,探讨了废铁屑的循环使用以及用废酸废碱调节pH值,实现“以废治废”的可能性,最后从Zeta电位、电导率等方面对最佳工艺条件下每步处理后的废液进行了表征。
运用该法对废液进行处理,最终将废液的COD_(Cr)值从59000mg/L降为为650mg/L,去除率达到了98.89%;含油量从11340mg/L降为31mg/L,去除率达到了99.73%,高于四步法处理此种废液的水平。
结果表明,改进后的处理方法既简化了操作,又节约了成本,并使COD_(Cr)值和含油量等指标与之前四步法相比进一步降低,具有一定可行性,是一种行之有效、简单便捷、经济适用的处理方法。
Waste liquid from line-cutting emulsion oil is a kind of highly steady liquid containing oil, high value of COD_(Cr)(chemical oxygen demand content), high concentration of contaminants and complex composition. To solve the problem of these waste liquid's discard in small mills which were dispersive and pint-sized in the remote areas,a appropriate method is urgently required. To low COD_(Cr) value and the oil content,achieve the aim that the treated wastewater could meet the requirement of national discharge standard, the existing technics were predigested and optimized in this paper. In the preliminary stage,the four-stage treatment method of microelectrolysis flocculation microelectrolysis flocculation process was repeated, validated,analysed and summarized, and then the first stage of the treatment method was omitted, and the influence factors were predigested and optimized again. Moreover,in the micro-electrolysis process,the influence of the value of pH and the reaction time on the micro-electrolysis process were researched. The possibility of the raw material's reclaim and recycle were discussed. Finally,the treated wastewater were characterized by the measure of Zeta potential and conductance on each best condition. After treatment,the waste liquid's COD_(Cr) value and the oil content were reduced to 650mg/L and 31mg/L from 59000mg/L and 11340mg/L respectively,and the removal rates arrived at the percent of 98.89 and 99.73. And the effect of treating waste liquid by the three-stage treatment method was better than better than that by four-stage treatment method. The result showed that the three-stage treatment by improving and optimizing previous four-stage method could predigest manipulation,save the cost, and was a simple treatment method. So it was of high value of application.
