（4）Waste water gravity flow after except lead reaction enters coagulation reaction tank, manually controls dosing coagulant PAC, the primary chemical of PAC
Substance is aluminium polychloride, and aqueous solution is the hydrolysate between alchlor and aluminium hydroxide, band colloidal electric charge, to water
In suspended matter there is very strong adsorptivity, mechanical stirring device is set in the reaction tank；
（5）Waste water gravity flow after coagulating enters flocculation tank, manually controls and adds flocculant PAM, PAM is macromolecule
Polymer --- polyacrylamide, make to form " bridging " between the particle being adsorbed herein using the acylamino- of polyacrylamide,
Floc sedimentation is generated, accelerates the sinking of particulate, achievees the purpose that removal, mechanical stirring device is set in the reaction tank；
（6）Mud mixture after flocculation reaction flows through distribution reservoir, enters back into rectangular sedimentation tank, reduces to subsequent flat flow
The impact of sedimentation basin；
（7）Waste water flows automatically after distribution reservoir enters rectangular sedimentation tank, is separated by solid-liquid separation using gravitational settling；
（8）Supernatant through sedimentation basin solid-liquid separation is kept in and is provided for subsequent filter-press from intermediate pool is flowed into
Water source；
（9）Intermediate waste water after pressurized has after sand filtration removes tiny particles content, then through active carbon filtering absorption residue
Machine object and heavy metal lead ion are to ensure wastewater to reach standard；
（10）Waste water after purified is kept in herein in case reuse.
9. a kind of wastewater treatment method of lead refinery according to claim 8, it is characterised in that：It is generated after the flocculation
The sludge struck off after sludge and advection sedimentation enters in sludge concentration tank after collection, then is dehydrated by sludge filter press, shape
At dewatered sludge otherwise processed, and the filtrate after sludge dewatering is back in conditioning tank and handles again.
10. a kind of wastewater treatment method of lead refinery according to claim 8, it is characterised in that：The step（4）And step
Suddenly（5）In PAC and PAM combination, reinforce coagulation and flocculating effect, assist to capture hydroxide precipitated metal, and go in water removal
Other polluters.
