摘要：

A　new　type　of　activated　carbon　was　prepared,　using　the　sewage　sludge　as　the　main　raw　materials　and　combining　the　waste　paper　materials.　The　sewage　sludge　was　taken　from　Gaobeidian　wastewater　disposal　plant　and　the　waste　paper　materials　were　added　to　improve　the　property.　And　the　concerned　conditions　were　worked　out　during　the　production.　The　chemical　activation　method　was　applied　to　pyrolyze　sewage　sludge　and　the　optimum　conditions　were　obtained　through　the　orthogonal　test.　Characteristics　of　the　activated　carbon　from　sewage　sludge　were　affected　by　4　factors　and　the　optimum　conditions　were　obtained:　750°C　of　heating　temperature,　60　min　of　dwell　time,　4　mol/L　of　the　concentrations　of　ZnCl2　activation　and　40%　of　the　proportion　of　waste　paper　materials　added.　The　SBET　value　of　the　activated　carbon　under　optimum　conditions　was　680.85　m2/g,　which　was　consistent　with　the　theoretical　result　of　orthogonal　design.
