Sewage sludge ash(SSA) was prepared by pyrolysis of municipal waste water treatment plant sludge, and adsorbing on removal of Cu(Ⅱ) from wastewater by sewage sludge ash was tested. In the batch experiments, parameters including the reaction time,solution pH value,dosage of sewage sludge ash,initial concentration,and temperature ion intensity were studied. The study provides scientific basis for the removal of Cu(Ⅱ)by sewage sludge ash.%以城市污水处理厂污泥为原料热解制得污泥灰，对吸附模拟废水中Cu2＋离子的反应条件进行研究，考察了反应时间、溶液pH值、污泥灰投加量、初始浓度、温度、离子强度等因素，对探讨污泥灰去除废水中Cu2+可行性提供科学依据。
