[Kinetics of Electro-Fenton treatment of leachate from municipal solid waste incinerator].
SPR electrode was used in Electrio-Fenton treatment on the effluent from biological and coagulative treatments of solid waste incinerator leachate, at the same time, the kinetics model for the COD effluent concentration were set up. The result indicated that the disposal curve of COD confirm to the pseudo third order kinetics, and the formula is c(t) = (2kt + c(0)(-2))(-0.5), in which the c(t) is the COD concentration of treatment effluent. With the statistical analysis to the disposal curve of COD from Electro-Fenton treatment in different conditions, the experience mathematics model of k value was set up, in which the current density, pH value and COD concentration of influent are effective factors. Moreover, with the comparison between the simulative COD of effluent and the experimental results, it was showed that this kinetic model could be used to investigate the COD disposal efficiency of Electro-Fenton treatment on the effluent from biological and coagulative treatments of solid waste incinerator leachate preferably.
