The invention relates to a garlic
wastewater treatment method and a device. The garlic
wastewater treatment device comprises a
wastewater regulating tank, an advanced oxidation reaction
sedimentation tank, a multistage hypoxic and
anaerobic reaction tank, an aerobiotic contact oxidation tank and a multilayer aerobiotic activity
filtration tower, wherein the advanced oxidation reaction
sedimentation tank comprises a mixing region and a
sedimentation region; the multistage hypoxic and
anaerobic reaction tank comprises a
facultative section, a hypoxic section and an anaerobic section; an
aeration controlling
system is arranged at the middle lower part in the aerobiotic contact oxidation tank and comprises an
aeration disc, an
air blower and a dissolved
oxygen measurement controlling device; and the multistage hypoxic and
anaerobic reaction tank adopts multistage arrangement, particle sizes of a
filter material are gradually decreased from top to bottom, an air inlet, a
water collection groove and a water outlet
pipe are arranged at the bottom of the
filtration tower, and disinfection equipment is installed at the upper part of the
water collection groove and is connected with a
chloride dioxide generator. The garlic wastewater treatment device has a simple structure, is lower in manufacturing cost, is suitable for
sewage treatment of larger volume and has very good treating effect to garlic wastewater.
