摘要：

Steel sludge, a byproduct generated from wastewater treatment in the steel industry, has high levels of iron salts and heavy metals, while traditional treatment technologies such as land application, sanitary landfilling, and incineration make resource recovery and utilization challenging. In this study, iron-rich sludge biochar (FSB) was prepared by one-step pyrolysis of iron-rich sludge generated from a steel factory and utilized to activate peroxydisulfate (PS) for tetracycline (TC) removal. Results showed that FSB pyrolyzed at 450 ºC ...
