< < when 5.2, waste liquid enters hydrolysis acidification pool for 3JTU, pH；
Step 4, waste liquid stands 36 ~ 48h in second pond, filters, and solid enters flocculation basin and enters Treatment of Sludge route, liquid
Enter secondary oxidation pond；Waste liquid under conditions of ozone concentration is 32% ~ 48%, enters after oxidation 2 ~ 3h in secondary oxidation pond
Hydrolysis acidification pool；
Step 5, enters in hydrolysis acidification pool, adds hydrolytic reagent, after acidification hydrolization 5 ~ 8h；Through jet aeration tanks, in reflux ratio it is
Jet-flow aeration 18 ~ 20h under conditions of 0.6:1, eventually passes multimedium pond and filters through exchanger resin, electrodialysis filtration and reverse osmosis
Filtered fluid discharge thoroughly, solid enters second pond.
