吸附-电解协同法处理铜氨络合废水

针对铜氨络合废水处理难度大、工艺复杂等问题，提出了吸附-电解协同处理的新方法。以模拟铜氨络合废水为研究对象，考察了电解时间、电流密度、电解温度等因素对电解法的影响；并以此为基础，将改性油酸吸附剂涂覆在阴极表面，采用正交试验方法研究了吸附-电解联合处理铜氨络合废水的协同作用。结果表明，吸附-电解协同法在电流密度为0.01A/cm2时对铜氨络合废水处理15 min，即可使铜离子去除率达到93%以上，电流密度小、处理时间短且电流效率明显提高。

The treatment of copper ammonia complex wastewater

The traditional treatment of copper ammonia complex wastewater is difficult and complicated. In order to solve the existing problems, a new treatment technology based on an adsorption-electrolysis synergistic reaction has been explored. Using simulated copper ammonia complex wastewater, the effects of varying the electrolysis time, current density and electrolyte temperature were investigated. In the orthogonal experiments, the surface of the cathode was coated with a modified oleic acid adsorbent and the effect of the adsorption-electrolysis synergy in copper ammonia complex wastewater treatment was studied. The results showed that, with a current density of 0.01A/cm2 and treatment for 15 min, the adsorption-electrolysismethod could remove 93% of copper ions. The new method requires a smaller current and shorter processing time than the conventional method, whilst giving higher current efficiency.
