Abstract:With the continuous improvement of urban development level in China, the demand for fine management of urban organic solid wastes such as sludge of wastewater treatment plant (WWTP) and organic domestic waste has been upgraded. It is particularly important to choose an economical and efficient organic solid waste treatment model. In view of urban organic solid waste treatment and recycling in China, three modes of all centralized treatment, fully distributed treatment and partially distributed treatment are proposed. And the three different treatment modes are comprehensively evaluated by the analytic hierarchy process (AHP). The evaluation results show that the priority of urban organic solid waste treatment modes is the partially distributed treatment, all centralized treatment and fully distributed treatment in turn, which provides ideas and technical support for efficient treatment and recycling of urban organic solid waste in China.
