关于含铜废水的治理,尤其是高浓度含铜废水的治理,早在五十年代就从事了研究,因为铜是较贵重的金属,回收价值高,而含铜废水又是公害之一。当水中含铜达0.5毫克/升时,水就变红,达1毫克/升时,水的浑浊度明显增加,且在皂液作用下形成绿色沉淀,达1.5毫克/升时,水产生异味,饮用含铜量较高的水,一般引起心血管疾病的死亡率增高,此外还损害人体的肠胃、肝 The treatment of copper-containing wastewater, especially the treatment of high-concentration copper-containing wastewater, was studied as far back as the 1950s because copper is a more valuable metal with a high recovery value and copper-bearing wastewater is one of the public hazards. When the water contains 0.5 mg / L copper, the water turns red, up to 1 mg / L, the water turbidity increased significantly, and the formation of a green precipitate under the action of soap, up to 1.5 mg / L, the water smell , Drinking water with high copper content, generally cause increased mortality of cardiovascular disease, in addition to damage the body’s stomach, liver
