2. use the method that bamboo product Waste Water Treatment as claimed in claim 1 carries out waste water process,
There are following steps:
1. bamboo product waste water enters wastewater equalization pond regulating water quality and the water yield by water inlet pipe；
The most then waste water enters the middle and lower part of strengthening flotation tank Disengagement zone by water inlet pipe (1-1)；It is positioned at strengthening
Aeration plate (1-6) below flotation tank water inlet pipe produces a large amount of tiny bubble makes the solids generation in waste water rub
Wipe, remove other pollutant on solids；The tiny bubble that aeration plate (1-6) produces adheres to supernatant
Form mixture to rise under buoyancy, under the effect of strengthening flotation tank three phase separator (1-9), mixed
Zoarium rises to Ji Zhaqu (1-5), and under the effect of scum board (1-11), scum silica frost enters scum trough (1-12)
And cleaned outward transport；Precipitate sinks to strengthen the silt particle district (1-2) of flotation tank bottom under gravity,
Discharged by the sediment discharge valve (1-13) bottom strengthening flotation tank；Water after separating treatment is at strengthening gas
Enter strengthening flotation tank gathering ground (1-4) under the deflector effect of Fu Chi three-phase separation area, pass through overfalling weir
(1-10), outlet pipe connects the water inlet pipe (2-5) of ozone oxidation sedimentation tank with connecting tube；
3. waste water enters ozone by ozone oxidation sedimentation tank water inlet pipe (2-5) and water distribution branch pipe (2-4)
The middle and lower part of oxidization and sedimentation basin (2)；It is positioned at the ozonation aerated dish below ozone oxidation sedimentation tank water distribution branch pipe
(2-3) producing a large amount of tiny bubble makes the solids in waste water rub further, simultaneously big point in waste water
Sub-material is oxidized to be prone to absorb and the small-molecule substance of absorption, and the waste water after oxidation Decomposition enters settling zone
Waste water runner, the three phase separator (2-9) of settling zone realizes mud-water separation；Mud under gravity under
Sink to the bottom of ozone oxidation sedimentation tank settling zone (2-2), discharged by the mud valve (2-11) of bottom；
Waste water enters the water inlet pipe of deflector type anoxia anaerobic reation pool by overfalling weir (2-10), outlet pipe and connecting tube
(3-5)；
4. waste water by deflector type anoxia anaerobic reation pool hold concurrently oxygen section water inlet pipe (3-5) enter deflector type anoxia
The bottom of anaerobic reation pool (3)；Waste water enters deflector type anoxia anaerobic reation pool tailing edge deflection plate (3-1)
Advance up and down, pass sequentially through double oxygen section (3-2), anoxia section (3-3) and anaerobism section (3-4) each instead
Answering the Sludge Bed of room, the mud in reaction tank moves along with flowing up and down and the effect of biogas rising of waste water,
The barrier effect of deflection plate (3-1) and the settlement action of mud self make again the flow velocity of mud reduce, the most greatly
The mud of amount is all trapped within reaction tank, and the microorganism in reaction tank is fully contacted with the Organic substance in waste water；
The heterotrophic bacteria of the amphimicrobe of oxygen section (3-2), anoxia section (3-3) and the anaerobism section (3-4) held concurrently is by waste water
Hydrolysis of organic matter is organic acid, makes larger molecular organics be decomposed into small organic molecule, insoluble Organic substance
Change into dissolved organic matter；
5. the three phase separator (3-6) that the waste water after anaerobic reaction is provided with at anaerobism section (3-4) end realizes
Mud, water, the separation of methane gas, mud sinks to deflector type anoxia anaerobic reation pool under gravity
Bottom, unnecessary mud is discharged by the mud discharging valve (3-8) of bottom；Deflector type anoxia anaerobic reation pool
The methane waste product produced collects discharge by reaction tank top discharge (3-10)；Waste water by overfalling weir,
Outlet pipe and connecting tube enter the water inlet pipe in aerobic contact oxidation pond (4)；
6. waste water enters the middle and lower part in aerobic contact oxidation pond (4) by water inlet pipe (4-1), at water distribution three
Water distribution uniformity under the effect of pyramid (4-2), described aeration plate is the pore type aeration being evenly arranged with micropore
Dish, produces substantial amounts of microbubble, and described dissolved oxygen sensing regulation device works according to oxygen content regulation and control aerator,
Guarantee that the dissolved oxygen in aerobic contact oxidation water passes through downflow weir (4-5) more than 2mg/L, the waste water after process
Flow out with outlet pipe；
7. the outlet pipe of aerobic contact oxidation pond (4) connects the water distributor of second pond, the precipitating sludge of second pond
A part of sludge reflux is in deflector type anoxia anaerobic reation pool (3), and a part is as excess sludge；
8. the water after sedimentation in secondary sedimentation tank processes enters sand filter, qualified discharge after filtration through second pond downflow weir；
9. strengthen flotation tank (1), ozone oxidation sedimentation tank (2), deflector type anoxia anaerobic reation pool (3),
Transport outward with after the excess sludge dehydration of second pond discharge.
