摘　　要：试验从实际条件出发,剔除了温度、压强、少量重金属离子等各种不可控因素的影响,研究了废水处理药剂——石灰及液碱的最佳添加量,并比较了反应沉淀物的体积。在试验条件下,处理1 L某区域含铜酸性废水需添加石灰5 g,或添加液碱8 m L,废水静置24 h后,添加石灰的反应沉淀物体积为150 m L,添加液碱的反应沉淀物体积为340 m L,其上清液均符合污水一级排放标准。综合各种因素,处理某厂的含铜酸性废水采用石灰仍具有优势。Proceeding from practical condition, eliminates the influence of uncontrollable factors such as temperature, pressure ,tiny amount of heavy metal ions and so on, the research focuses on the optimal adding amount of the agentia,lime and sodium hydroxide, for wastewater treatment, and compares volumes of different reacting sediments. Under experiment condition, 5 g of lime or 8 mL of sodium hydroxide are needed for treating 1 liter of coppercontaining acid waste water. After 24 hours standing of the wastewater, the volume of lime reacting sediment is 150 mL and sodium hydroxide ＇s reacting sediment is 340 mL, both of the supernates comply with GB18918-2002. Considering all factors, applying lime to treat copper-containing acid waste water still have advantages.
