Embodiment 1
[0038] The combined process disclosed in the present invention is used to treat the leachate of an industrial waste landfill in an industrial waste landfill in Taizhou, Zhejiang. The leachate of the industrial waste landfill is mainly after landfilling and dismantling electrical appliances, chemical waste, leftover materials, etc. The resulting leachate, the COD concentration of the leachate before treatment is 8500mg / L, the BOD concentration is 75mg / L, and the NH 3 -N concentration is 600mg / L, suspended solids concentration (SS) concentration is 1100mg / L, total lead concentration is 5mg / L, total nickel concentration is 2.5mg / L, total zinc concentration is 1.5mg / L, total copper concentration The concentration is 12mg / L.
[0039] (1) Use a double-pipe DN150 conveying system to collect leachate from industrial waste landfills, and collect the leachate into the storage tank, and feed the leachate with a ventilation volume of 0.6m 3 / m 3 The air is pre-aerated, and then the leac...
