Problems solved by technology

[0004] Due to the large landfill area, the number of buried temperature sensors in the garbage dump is limited, and the remote control system can only alarm based on the temperature results obtained from monitoring. The existing monitoring and early warning technology cannot realize the prediction of the temperature in the dump

Abstract

The invention belongs to the technical field of refuse disposal, and particularly relates to a method of predicting the temperature of an aerobic ventilation refuse landfill. The prediction method comprises the following steps of: determining the basic attribute parameters of the refuse landfill; calculating the temperature prediction result of a refuse dump under the basic attribute parameters; determining the temperature result of the refuse dump; and correcting the temperature result obtained by predicting. The method can provide a solution for predicting the temperature of the refuse dumpin the aerobic ventilation process, can avoid the outbreak of fire and explosion accidents caused by mixed gas, and guarantees the high-efficiency operation of an aerobic ventilation system to the maximum extent, and has relatively good practicability and flexibility in the aerobic ventilation project.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, in particular to an aerobic ventilation type garbage landfill temperature prediction method. Background technique [0002] Aerobic ventilation is a mainstream method for in-situ restoration of landfills. Its technical principle is to inject air into the garbage dump to accelerate the degradation of organic matter in the garbage in an aerobic environment, thereby reducing the concentration of methane and reducing The purpose of leachate discharge and in situ elimination of sources of contamination. [0003] The degradation rate of organic matter in the process of aerobic ventilation is accelerated, resulting in an increase in the temperature of the garbage dump. After the air is injected into the garbage dump, the oxygen in the air reacts with the methane in the garbage dump to produce carbon dioxide and water, which are consumed simultaneously. However, the garbage dump has strong het...
