Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] refer to figure 1 Shown is a schematic flow chart of an early municipal garbage permeate treatment method, which specifically includes:
[0022] Step 101, adding anaerobic sludge to the ASBR reactor, adding aerobic active and denitrifying sludge to the pulsed SBR reactor, performing sludge acclimatization and cultivation, and keeping the MLVSS of the pulsed SBR above 6000 mg / L;
[0023] Step 102, add the original leachate into the water inlet tank, start the ASBR water inlet pump, the original leachate enters the ASBR through the ASBR water inlet instantaneously, and when the incoming amount is half of the effective volume of the ASBR, turn on the mechanical stirring device in the ASBR, and react a cycle process when When the COD of ASBR effluent is maintained at 1100±100mg / L, stop the stirring device for mud-water separation;...
