A　continuous　batch　bioleaching　was　built　to　realize　the　bioleaching　of　sewage　sludge　in　large　scale.　In　the　treatment,　heavy　metal　in　acid　wastewater　of　bioleaching　was　removed　by　adsorption　onto　ramie　residue.　Then,　acid　wastewater　was　reused　in　next　bioleaching　batch.　In　this　way,　most　time　and　water　of　bioleaching　was　saved　and　leaching　efficiency　of　copper,　lead　and　chromium　kept　at　a　high　level　in　continuous　batch　bioleaching.　It　was　found　that　residual　heavy　metal　in　sewage　sludge　is　highly　related　to　that　in　acid　wastewater　after　bioleaching.　To　get　a　high　leaching　efficiency,　concentration　of　heavy　metal　in　acid　wastewater　should　be　low.　Adsorption　of　copper　from　acid　wastewater　onto　ramie　residue　can　be　described　by　pseudo　first-order　kinetics　equation　and　Freundlich　isotherm　model.　Trichoderma　viride　has　the　potential　to　be　used　for　the　concentration　and　recovery　of　heavy　metal　adsorbed　onto　ramie　residue.　(C)　2013　Elsevier　Ltd.　All　rights　reserved.
