摘　　要：用实验方法分析了重油加氢废催化剂中的污染物的特性及对环境的影响程度．通过水浸实验、用碳酸钠沉淀化合物实验以及废渣的淋溶实验研究了废催化剂中有害毒物的浸出方法．实验结果表明，为了控制废催化剂污染环境，在反应器中循环注水，再用碳酸钠沉淀出催化剂中的镍化合物，可用于回收镍．废水可直接排放掉，浸出的废渣送炉焚烧２４ｈ后装桶填埋掉．The properties of pollutants from the waste catalyst are analyzed by experiments. The removal of polluents of waste catalyst is studied. Some proceedings to deal with the pollutant nickel in waste catalyst are proposed. Water is injected circulately into the reactor with catalyst. Nickel compound deposited from the waste catalyst by the use of carbonate natrium can be used to recovery processing of nickel. The waste water can be discharged from the reactor. The waste residue is burned for two hours at the temperature of 850 ℃ and can be buried underground.
