The present invention discloses a large circulation garbage percolate treatment process with a characteristic of adaptability. The process is characterized in that the following improvements are performed based on the conventional garbage percolate treatment process, wherein the improvements comprise that: an ultra-
filtration effluent reflux system is added, and comprises four parts such as
reflux of ultra-
filtration effluent to an adjustment tank,
reflux of ultra-
filtration effluent to an anaerobic tank, reflux of ultra-filtration effluent to a
denitrification tank and reflux of ultra-filtration effluent to a
nitrification tank, two parts such as reflux of ultra-filtration concentration
sludge to the anaerobic tank and reflux of ultra-filtration concentration
sludge to the adjustment tank are added, a pipeline transcending
system is added so as to perform direct transcendence entering of the percolate raw liquid into the
denitrification tank, and a
fuzzy control system is additionally arranged. The process has the following beneficial effects that: self-circulations of various process segments in the
system in the
large range are flexibly regulated so as to effectively reduce
impact on the system due to substantial organic load fluctuation, ensure long time stable operation of the system, and achieve an adaptability function of the garbage percolate treatment process; and structure sizes of various reactors can be properly reduced, capital construction investment and
operating cost can be saved, foams in the
nitrification tank can be effectively eliminated, and other effects are provided.
