The present invention discloses a resource utilizing method of refuses in urban and rural areas in which an acidification and anaerobic treatment tank, an additional anaerobic treatment tank, a biogas gathering tank and a gas generator set are provided and a gas inlet of said gas generator set is connected to the biogas gathering tank through pipes. The method comprises a refuses reception step, a uniform refuses distribution step, a primary magnetic separation step, a primary crushing step, a primary elutriation and floatation step, a uniform cutting step, an acidification and anaerobic treatment step, a selection and separation step, a buffering and adjusting step, an additional anaerobic treatment step and a sludge sedimentation and concentration step. In the present invention, the refuses need not pre-sort as the sorting and selection of the refuses are made throughout the overall process of the inventive refuses utilizing method. Thus the biggest bottleneck of the constraints in refuses disposal is removed. The present invention can make the anaerobic treatment method continuatively dispose the refuses, thereby thoroughly solving the problem that the non-anaerobic refuses such as waste plastics, waste fibers etc. can't be recycled and completely recycling resources in the refuses.
