去除城市污泥中的重金属中试研究

Removal of Heavy Metals in Sludge in A Pilot Study

文章以含有重金属的城市污水处理厂污泥为研究对象,在实验室研究的基础上,采用吸附法去除城市污泥中的重金属,选用合适的中试设备,找到了的最佳吸附工艺条件:p H=4和反应时间为3小时下重金属的去除效率最高。

The paper takes the heavy metal containing sludge of city sewage treatment plant as the research object. Based on laboratory research, Removal of heavy metals from sludge in the city by the adsorption method, the appropriate test equipment was selected, find the best adsorption process conditions： The heavy metal of removal effeciency was the best when the pH=4 and the reaction time is 3 hours.
