Embodiment 1
[0035] A method for treating landfill leachate and fermented biogas slurry using a treatment system for realizing zero discharge of landfill leachate and fermented biogas slurry according to the present invention comprises the following steps:
[0036] (1) The fresh wastewater composed of landfill leachate and fermented biogas slurry is sent from outside to the buffer tank 1, and then sent to the feed water preheater (plate-and-frame heat exchanger) 3 by the feed pump 2, where Perform heat exchange with the condensate of the MVR steam generated by the MVR evaporator 9, and further cool the MVR condensate while initially preheating the waste water to obtain preheated waste water;
[0037] (2) The preheated waste water is sent into the tower from the waste water inlet on the upper part of the analysis tower 4, and the stripping distillation process is adopted in the analysis tower 4 to strip part of the ammonia nitrogen in the waste water to obtain the stripped waste water; The ...
