摘　　要：高氯废水对管道设备具有很大腐蚀性,处理困难。利用氢氧化钙和偏铝酸钠与水中氯离子结合形成不溶性的沉淀物Ca_2Al(OH)_6Cl,以达到去除氯离子的效果。在最优条件下对山西某发电厂高氯废水进行处理,结果表明,Ca^(2+)∶Al^(3+)∶Cl^-摩尔比为10∶4∶1,2次投加药品的质量比为1∶2,氯离子去除率高达90%;实验中获得的Ca_2Al(OH)_6Cl对实际废水中金属Mn去除率高达99%。High chlorine wastewater is very corrosive to pipeline equipment. However,the removal of chlorine is difficult. In this study,calcium hydroxide and sodium aluminate are used to remove chilorine by reacting with chloride ions to form water insoluble sediment,Ca_2Al（OH）_6Cl. Under the optimal high chlorine wastewater treatment conditions of a power plant in Shanxi,chloride ion removal rate is as high as 90% with 10 ∶ 4 ∶ 1 of Ca^（2＋）∶ Al^（3＋）∶ Cl^- and 1 ∶ 2 of calcium hydroxide and sodium aluminate. For the obtained Ca_2Al（OH）_6Cl,the manganese removal rate for actual wastewater is 99%.
