某黄金矿山含氰废水呈碱性,主要污染物为总氰化合物及重金属离子。采用因科法、酸化法、过氧化氢氧化法、CG101-A药剂法、电解法等多种方法进行破氰处理。探索试验发现,因科法和CG101-A药剂法的去除效果较好。进一步条件试验揭示,对于该黄金矿山含氰废水而言,CG101-A药剂法是最为适宜的处理工艺。在CG101-A投加量为3 g/L,且分3次均匀投加,反应pH值控制在8~9,反应时间为2 h条件下,总氰化合物的去除率可达到99.5 %。试验结果为黄金矿山含氰废水处理提供了新的思路和方法,有助于推动该领域的技术进步和环境保护。
The cyanide-containing wastewater from a gold mine is alkaline and major pollutants are total cyanide compounds and heavy metal ions. Various cyanide removal methods,including Inco process,acidification process,hydrogen peroxide oxidation,CG101-A reagent method,and electrolysis,were tested. Exploratory tests found that the Inco process and the CG101-A reagent method exhibited better cyanide removal efficiency. Further conditional tests revealed that the CG101-A reagent method is the most suitable treatment process for this wastewater. Under the conditions of a CG101-A dosage of 3 g/L (added in 3 equal portions),a reaction pH of 8-9,and a reaction time of 2 h,the total cyanide compounds removal rate reached 99.5 %. The findings provide new insights and methods for the treatment of cyanide-containing wastewater in gold mines,contributing to technological progress and environmental protection in this field.
