Abstract

The invention discloses a soilless covering agent in the field of landfill treatment. The soilless covering agent comprises the following raw materials in parts by weight: 700-750 parts of sludge, 950-1000 parts of garbage concentrate, 100-120 parts of straws, 60-70 parts of newspaper and 720-750 parts of clay. The soilless covering agent disclosed by the invention is a comprehensive utilization of the garbage concentrate and the domestic sludge; thallus in the sludge is adhered to the straw and the newspaper, and colloids and the clay in the sludge can be quickly cured, and further, a curingfilm is formed, therefore, a suitable growth environment is provided for microorganisms, the sludge is reasonably treated, and the problem that the garbage leachate concentration is higher and higherwhile the decomposition treatment of garbage is facilitated.

Description

technical field [0001] The invention belongs to the field of waste landfill treatment, and in particular relates to a soilless covering agent and a landfill waste treatment method thereof. Background technique [0002] Waste disposal methods can generally be divided into several methods such as sanitary landfill, incineration, and composting. Garbage landfill is a place where garbage is piled up under the sanitary landfill method. Garbage sanitary landfill is widely used in China because of its low cost and good sanitation. The largest landfill in China is Guangzhou Xingfeng Landfill, which handles about 7,000 tons of domestic waste every day. Garbage landfills generally use layered soil-covering methods to process garbage, pile up a layer of garbage and then cover it with a layer of loess. Adopting such a method wastes the storage capacity, and the cost is high, which is not conducive to the natural degradation of landfill waste and the recovery of landfill leachate. [...
