A method for processing leachate ultrafiltration membrane treatment process liquid

The present invention relates to a method for processing a leachate ultrafiltration membrane treatment process liquid using electric Fenton treatment was subjected to ultrafiltration, adjusted to pH 2-5, the ferrous ion concentration of 0.1-1.5mmol / L ; controlled aeration rate was 1.0L / min, a current density of 15-35mA / cm2, continuous reaction over 1h. The present invention fully utilizes the existing high conductivity and high concentrations Cl- ultrafiltration concentrate Implementing "by Waste", the use of electric Fenton method, good effect, high efficiency, COD and NH3-N current high efficiency, low energy consumption; was effective to reduce COD and NH3-N concentration after treatment was concentrated, greatly reduced the impact of the concentrate to reflux during the treatment process leachate membrane bioreactor.
