Research Progress on the Resource Utilization of Aged Waste in Domestic Waste Landfill
The key to the treatment of domestic waste landfill lies in the comprehensive utilization of aged waste,with humic soil and light sieve residue as its main components.The current research status of resource utilization of humic soil and light sieve residue is summarized based on the composition and physicochemical characteristics of aged waste.Among them,humic soil is mainly used as engineering materials,biological fillers,and nutrient soil,and the light sieve residue is mainly recycled for energy by entering the garbage incinerator for incineration or collaborating with the cement kiln for disposal.At present,the treatment capacity of humic soil resource utilization technology is relatively small,and there is heavy metal pollution;burning light sieve residue will emit exhaust gas,which contains various pollutants.Therefore,while improving existing ways of resource utilization,new ways of resource utilization should be expanded.
