Urban refuse landfill is the most basic disposal method for urban refuse. Although municipal waste can be disposed of by incineration, composting, or sorting recovery, the remainder of the waste, which is difficult to dispose of, still requires final landfill disposal. Urban garbage is buried by utilizing the hollow zones, so that the waste can be disposed, and the soil can be covered to make land, thereby protecting the environment. The urban refuse landfill method mainly comprises the following steps: (1) sanitary landfill. Pouring a layer of urban garbage (60 cm thick), compacting, covering with 15 cm thick soil, sand or fly ash, repeating the steps, and covering with 90-120 cm surface soil. (2) compressed landfill. The garbage is backfilled after being compressed, so that the garbage can prevent fire and mosquito breeding and is slowly decomposed. (3) breaking up the landfill. Can prevent fire and is favorable for the propagation of aerobic bacteria. The lowest part of the landfill site of the urban garbage should be higher than the ground water level by more than 3 meters, and the landfill site should take anti-seepage and exhaust measures.
