Liquid in step 2:pH conditioning tank imports coagulating basin by through-hole, is then added 0.5% by ZA-L/K coagulant tank
Coagulant, make the fine particle for being difficult to precipitate in water, impurity combine form bigger floccule body；
Step 3: the liquid in coagulating basin enters first stage precipitation tank standing by the first diversion trench, and most floccule body is deposited to
Bottom, and extracted out by sludge pump；
Step 4: the liquid on first stage precipitation tank upper layer enters level-one AOP oxidation pond by the first catheter, then passes through ZA-A/F/
The strong oxidizer that B strong oxidizer tank is added 0.5% decomposes and removes the organic matter in sewage, reduces COD value in water；
Step 5: the liquid in level-one AOP oxidation pond enters second-level settling pond standing by the second diversion trench, makes new floccule body
It is deposited to bottom, and is extracted out by sludge pump；
Step 6: the liquid on upper layer enters second level AOP oxidation pond by the second diversion pipe in second-level settling pond, then passes through ZA-O3
0.5% oxidant is added in oxidant tank, so that chromophoric group in water is decomposed disengaging, reduces the coloration in sewage；
Step 7: the clear water on second level AOP oxidation pond upper layer is directly taken over by clear water reserviors and is discharged, and sludge pump leads all sludge
Enter sludge-tank, after sludge condensation, enters filter press processing, the mud cake outward transport of generation, the clear liquid on upper layer by sludge screw pump
It is back to landfill yard conditioning tank.
