When turbidity >=3JTU, waste liquid enters secondary settling tank；As turbidity<3JTU, when pH value>=5.2, waste liquid enters secondary oxidation pond；Work as turbidity
When < 3JTU, pH < 5.2, waste liquid enters hydrolysis acidification pool；
Step 4, waste liquid stand 36 ~ 48h in secondary settling tank, and filtering, solid enters flocculation basin and enters Treatment of Sludge route, liquid
Into secondary oxidation pond；Under conditions of waste liquid is 32% ~ 48% by ozone concentration in secondary oxidation pond, enter after aoxidizing 2 ~ 3h
Hydrolysis acidification pool；
Into in hydrolysis acidification pool hydrolytic reagent is added, after 5 ~ 8h of acidification hydrolization in step 5；Through jet aeration tanks, it is in reflux ratio
18 ~ 20h of jet-flow aeration under conditions of 0.6:1, finally by multi-medium filtering pond by exchanger resin filter, electrodialysis filtering with
Liquid discharges after osmosis filtration, and solid enters secondary settling tank.
