Abstract

The invention discloses a method for processing garbage leachate by using a microbial fuel cell, which comprises the following steps of: starting the microbial fuel cell, which is to inject glucose simulating organic waste water into the microbial fuel cell to start the microbial fuel cell by using anaerobic sludge as inoculation liquid, wherein one period is completed when the voltage of the cell is less than 50mV; and 2) after the microbial fuel cell is successfully started, replacing the glucose waste water in an anode chamber with the mixed solution of glucose and garbage leachate, recording the voltage of the cell with a frequency of one point per minute, detecting chemical oxygen demand (COD) every other day and replacing the mixed solution of glucose and garbage leachate when a removal rate of the COD is over 80 percent. The method has the advantages that: the waste water is treated and organic pollutant in the waste water is converted into electric power at the same time; a process is simple, implementation is easy, cost is low, efficiency is high and the like; and treatment effects and electric power yield are hardly influenced, and the removal rate of the COD is high.

Description

technical field [0001] The invention belongs to sewage treatment technology, in particular to a method for treating landfill leachate by utilizing a microbial fuel cell. Background technique [0002] Municipal solid waste landfill, as one of the solid waste treatment methods, has been widely used at home and abroad. During the process of landfill and after the landfill is closed, it will be accompanied by the generation of landfill leachate. Landfill leachate is a highly polluting high-concentration organic wastewater. Research has found that the chemical oxygen demand (COD) and biochemical oxygen demand (BOD) of landfill leachate can reach 10 to 100 times that of urban sewage, and it contains a variety of toxic substances and carcinogens. If it is discharged directly without treatment , will seriously pollute groundwater, surface water and the surrounding environment, so it must be treated effectively. There have been many years of research on landfill leachate treatment ...
