摘要
为了改善含汞废水的治理效果和能耗效果,文章设计一种利用微生物结合传统水银电解技术处理含汞废水的改进工艺技术。选用试验试剂、原料、废水、其他物料,利用微生物发光原理优先检测废水的物产程度,结合实验结果,建立了水银电解法的试验方案,选择水银电解法进一步处理,并给出了处理流程,在微生物检测技术的帮助下,确定了最佳的节能处理工艺条件。最佳处理条件主要将pH值设定为2.5~3.0,有效氯50~100 ppm,同时,从脱除效果来看,采用水银电解技术深度处理含汞废水,达到零汞浓度,并取得了良好的效果,满足方法的节能设计需求。
In order to improve the treatment effect and energy consumption effect of mercury-containing wastewater, this paper designs an improved process technology that uses microorganisms combined with traditional mercury electrolysis technology to treat mercury-containing wastewater. It selected test reagents, raw materials, waste water and other materials, and used the principle of microbial luminescence to preferentially detect the product degree of waste water. Combined with the experimental results, a test scheme of mercury electrolysis method is established, and mercury electrolysis method is selected for further treatment. The treatment process is given. With the help of microbial detection technology, the best energy-saving treatment process conditions were determined. The optimal treatment conditions are mainly to set the pH value to 2.5~3.0 and the effective chlorine to 50~100 ppm. At the same time, from the perspective of the removal effect, mercury-containing electrolysis technology is used for advanced treatment of mercury-containing wastewater to achieve zero mercury concentration and achieve good results. The effect of the method meets the energy-saving design requirements of the method.
