摘要

In order to fulfill the SDG(Sustainable Development Goal)6.2 of the UN Agenda 2030 for sustainable developments,one needs to re-consider the wastewater management systems.In traditional approaches,sludge management plays a subordinate role in planning and designing wastewater systems since it is considered to be physically and conceptually at the end of the water cycle train.However,this does not take into account that the selection of the most appropriate treatment sequence for the wastewater treatment plants is strongly driven by the final reuse/disposal option(s)available in the specific local situation and consistent with it.Therefore,a re-conceptualization becomes necessary to put sludge management in a driving position of the water cycle train.This includes“technical”aspects and“institutional and governance”ones,which shall comply with general“basic principles”and fall within well defined“boundary conditions”.This paper discusses aforementioned items,paying greater attention to institutional and governance aspects.
