The invention relates to a kitchen garbage
slurry anaerobic
fermentation wastewater treatment method, in particular to a treatment method for treating
wastewater produced in other procedures through
wastewater produced after anaerobic
fermentation dehydration of kitchen garbage
slurry and kitchen garbage.
Wastewater is subjected to oil-separation primary
precipitation, water amount and
water quality adjustment, first pH value adjustment, free
ammonia stripping in an
ammonia stripping
tower, second pH value adjustment, A / O biochemical treatment,
precipitation treatment, treatment in a Fenton reactor and treatment in a coagulative
precipitation tank, so that pollutants such as COD, BOD5 and SS in the wastewater are removed, TN and TP can be removed effectively, the wastewater chroma can be lowered effectively, the TN and TP removing rates are increased, and pollutants such as COD, BOD5, TN, NH3-N, TP and chroma in the treated wastewater can stably meet the requirements in Integrated
Wastewater Discharge Standard (GB8978-1996, grade III standard) and
Wastewater Quality Standards for
Discharge to Municipal Sewers (GB / T 31962-2015, grade B).
