摘要
环保、节能降耗一直是我国产业发展的重要基石之一。在此基础上,重视含铬废水处理不仅能降低Cr6+的含量,还有利于改善区域内的水质环境。从发展的角度来说,化学沉降法使用Na2S2O5还原方法,有效降低六价铬、铜离子的含量,促使离子形成沉淀,满足标准排放要求。分析了化学沉淀法在处理含铬电镀水过程中的实践模型。
Environmental protection and energy conservation have been advocated by China’s industrial development.Therefore,attaching importance to the treatment of chromium-containing wastewater can not only reduce the content of Cr6+,but also help improve the water quality environment in the region.From the perspective of development,the chemical deposition method usedNa2S2O5 to effectively reduce the content of hexavalent chromium,potassium ions and copper ions,and promote the formation of these ions into precipitation to achieve the value of treatment.Based on the above,this paper focuses on the practical method of chemical precipitation in the treatment of chromium-containing electroplating wastewater.
