The Parameters Control of Recirculation Treatment for Leachate
View through CrossRef
The three parameters, hydraulic loading rate, organic loading rate and recirculation times have important influence on the efficiency of recirculation treatment, the recirculation experiment research removal of COD under different hydraulic loading rate, organic loading rate and recirculation times by the experimental devices built in landfill in a civil city. The result indicated that the hydraulic loading rate is the major influence parameter for leachate recirculation. When hydraulic loading rate was 30ml/L·d~200ml/L·d, COD removal efficiency was 70%~94%; However, organic loading rate has comparative minor influence on recirculation treatment; the apt recirculation times are 3 or 4 in a day; C/N of recirculation leachate have important influence on NH3-N removal rate, but the effect of hydraulic loading rate and recirculation times on NH3-N removal rate aren’t obvious.
