Weir (5-10)；Described mud district (5-3) be positioned at the bottom of reflux formula BAF, lower current area and on
The bottom in stream district, the bottom in mud district is provided with mud discharging valve (5-11)；
The standard water discharge discharge of described reflux formula BAF.
2. one kind uses mechanical blades as claimed in claim 1 to cut wastewater treatment equipment and carry out the side of waste water process
Method, has following steps:
1. waste water enters wastewater equalization pond regulating water quality and the water yield by water inlet pipe；
2. the water after regulation enters acid out breakdown of emulsion pond (1) by the water inlet pipe (1-1) bottom acid out breakdown of emulsion pond,
Acid solution is added and the pH value of pH value TT&C system (1-3) regulation waste water is 3-4, in acid condition waste water
In oil emulsion destructurized, become suspended state；
The most then waste water enters the middle and lower part of ozone oxidation flotation tank (2) by water inlet pipe (2-1)；It is positioned at
Aeration plate (2-6) below ozone oxidation flotation tank water distributor produces a large amount of tiny bubble, and ozone is in waste water
Macromolecular substances be oxidized to be prone to absorb and the small-molecule substance of absorption, the tiny bubble that aeration plate produces with
The dregs of fat adhere to form mixture and rise under buoyancy, at ozone oxidation flotation tank Disengagement zone three phase separator
(2-8), under effect, mixture rises to dregs of fat district (2-5), under the effect of dregs of fat scraper plate (2-10),
The dregs of fat enter crackling receiving tank (2-11) cleaned outward transport；Water after separating treatment is at ozone oxidation flotation tank three
Under phase separator deflector effect enter ozone oxidation flotation tank gathering ground (2-4), by overfalling weir (2-9),
Outlet pipe and connecting tube enter the water inlet pipe (3-3) of coagulative precipitation tank；
4. waste water enters coagulating sedimentation by the wastewater inlet pipe (3-3) bottom coagulative precipitation tank stirring mixed zone
Pond (3), regulation waste water is neutral, and waste water mixes with the coagulant from liquid add-on system (3-4), profit
It is stirred with the agitating device (3-5) being arranged in the middle part of stirring mixed zone；Waste water after coagulating enters
Settling zone (3-2), the three phase separator (3-7) of settling zone realizes mud-water separation；Mud is in the effect of gravity
Under sink to the bottom of coagulative precipitation tank settling zone (3-2), by the sediment discharge valve (3-9) of bottom
Discharge；Waste water enters entering of advanced oxidation reaction settling basin by overfalling weir (3-8), outlet pipe and connecting tube
Water conduit tube (4-1)；
5. the water after coagulating sedimentation passes through the water inlet main (4-1) of advanced oxidation reaction settling basin, radiant type cloth
Water pipe (4-3) enters advanced oxidation reaction settling basin (4), the peroxidating in sponge iron filling tube (4-2)
Hydrogen, sponge iron reactant salt produce the most active hydroxyl radical free radical, destroy the structure of Pollutants in Wastewater, useless
The oxidized decomposition of pollutant in water, the waste water after oxidation Decomposition is by overfalling weir (4-4), outlet pipe and company
Adapter enters the water inlet pipe (5-4) of reflux formula BAF；The sediments such as mud are under gravity
Sink to the bottom of advanced oxidation reaction settling basin (4), arranged by the sediment discharge valve (4-6) of bottom
Go out；
6. waste water enters the dirty of reflux formula BAF by water inlet pipe (5-4), water distributor (5-5)
District (5-1), the air that aeration tube (5-7) produces and waste water cross generation biochemistry instead in filler (5-6)
Should, waste water is filtered by filler simultaneously, and waste water enters ascending zone (5-2) afterwards by deflection plate (5-8),
Biochemical reaction occurs in filler, and waste water is filtered by filler (5-9) simultaneously, and lower current area and ascending zone produce
Raw mud sinks to mud district (5-3), is given off by the mud discharging valve (5-11) bottom mud district
Going, the water after reflux formula BAF processes is flowed out by overfalling weir (5-10), it is achieved qualified discharge；
7. coagulative precipitation tank (3), advanced oxidation reaction settling basin (4), reflux formula BAF (5)
Discharge mud concentrated, dehydration after transport outward.
