4. the wastewater inlet pipe (3-3) that waste water is uniformly mixed bottom district by coagulation precipitate reduction pond enters coagulation precipitate reduction pond (3), waste water mixes with from the coagulating agent of liquid add-on system (3-4) and reductive agent, utilizes to be arranged on the whipping appts (3-5) be uniformly mixed in the middle part of district and to stir; Waste water after coagulation reduction reaction enters waste water runner, the pH value regulating waste water is 9-10, waste water after adjustment enters settling region (3-2), and the copper in waste water, zinc generate throw out in the basic conditions, and the triphase separator (3-7) of settling region realizes mud-water separation; Mud sinks to the bottom of settling region, coagulation precipitate reduction pond (3-2) under gravity, is discharged by the sediment discharge valve (3-9) of bottom; Waste water enters the water inlet main (4-1) of advanced oxidation reaction settling basin by overfalling weir (3-8), rising pipe and pipe connecting;
5. the water after coagulation precipitate reduction enters advanced oxidation reaction settling basin (4) by the water inlet main (4-1) of advanced oxidation reaction settling basin, radiation formula water distributor (4-3), hydrogen peroxide in sponge iron filling tube (4-2), sponge iron reactant salt produce hydroxyl radical free radical active in a large number, destroy the structure of Pollutants in Wastewater, the oxidized decomposition of pollutent in waste water, the waste water after oxygenolysis enters the water inlet pipe (5-4) of reflux formula BAF by overfalling weir (4-4), rising pipe and pipe connecting; The throw outs such as mud sink to the bottom of advanced oxidation reaction settling basin (4) under gravity, are discharged by the sediment discharge valve (4-6) of bottom;
6. waste water is by water inlet pipe (5-4), water distributor (5-5) enters the lower current area (5-1) of reflux formula BAF, the air that aeration tube (5-7) produces and waste water cross generation biochemical reaction in filler (5-6), filler filters waste water simultaneously, waste water enters ascending zone (5-2) by after traverse baffle (5-8), biochemical reaction is there is in filler, filler (5-9) filters waste water simultaneously, the mud that lower current area and ascending zone produce sinks to mud district (5-3), emitted by the mud discharging valve (5-11) bottom mud district, water after the process of reflux formula BAF is flowed out by overfalling weir (5-10), realize qualified discharge,
7. the mud that coagulation precipitate reduction pond (3), advanced oxidation reaction settling basin (4), reflux formula BAF (5) are discharged is transported outward after concentrating, dewatering.
