It is disposed adjacent to the side of water outlet.
So set, the control of haptoreaction area contains by the way that processing unit is divided into haptoreaction area and contact precipitation area
Oxygen amount improves NH in the sewage of gardens3The removal effect of-N；Precipitation after reacting before contact precipitation area is improved to gardens
The multidomain treat-ment of sewage has the function of improving treatment effeciency.
Further setting：The pond the contact precipitation-BAF is cylinder, and light ceramic partial size is 2 ~ 5mm, and light ceramic
With a thickness of 600mm.
So set, haydite, because its material is light, large specific surface area, absorption suspending power is strong, and there is wear-resisting, resistance to erosion,
Micropore is more, and retaining power is strong；Turbidity, the NH in the sewage of gardens are controlled by light ceramic3The removal rate of-N and TN.
Further setting：The sterilization pool includes the ultraviolet disinfecting being set to above sterilization pool.
So set, passing sequentially through sewage collecting pool, combined multi-stage biological reaction pool and the processing of the pond contact precipitation-BAF
Later water quality has had the function of good recycling, handles again by ultraviolet disinfecting, has killing and bacterium
Effect, while eliminating part peculiar smell, improve the processing quality of gardens regeneration effluent system.
Further setting：The detection zone includes COD detector, BOD5Detector, transmissometer, TP detector and TN inspection
Survey at least one of instrument.
So set, corresponding content in the water quality crossed convenient for detection processing, is convenient for real-time control and regulating system, improve
The reliability of gardens regeneration effluent.
Another object of the present invention is to provide a kind of for being covered in light ceramic, the film covering method in elastic filler,
With the treatment effect improved to harmful substance in sewage and microorganism.
It is a kind of for being covered in light ceramic among the above, the film covering method in elastic filler, include the following steps：S1, it takes
Activated sludge in municipal wastewater treatment plant returned sludge well is as strain；S2, sludge is sprayed on to contact biological oxidation area simultaneously
The elastic filler surface in light ceramic and the pond contact precipitation-BAF introduces test water sample and carries out bored exposure, water continuation is changed after three days
Bored exposure is shortened change the water time as once a day up to visible obvious khaki biomembrane, light ceramic in elastic filler after a week
Upper attachment taupe biomembrane；S3, start dynamic cultivation and debugging after two weeks, flow of inlet water be gradually increased according to effluent quality,
Reach operation test water after three weeks, until the water outlet of regeneration effluent system is limpid, activated sludge area is in taupe, contact precipitation-
Uniformly adhere to the yellowish-brown biomembrane of 1mm left and right thickness in the elastic filler in the pond BAF, contacts the light ceramic in biological oxidation area
Upper biomembrane is in grey black.
So set, making activated sludge area, contacting the light ceramic in biological oxidation area and the bullet in the pond contact precipitation-BAF
Property filler surface be attached with biomembrane, keep the water outlet of its system limpid, activated sludge is in taupe, and activating agent settling property is good
It is good；UEFA Champions League is to NH in system3-N、BOD5、CODcr、TN agent turbidity removal rate is stablized, and improves to gardens regeneration effluent water quality.
Further setting：The DO in the activated sludge area is 0.8 ~ 1.5mg/L；Contact biological oxidation area in DO be 2 ~
3mg/L, HRT 3.5h, MLSS 1500g/L.
So set, effectively improve light ceramic, the biofilm formation in elastic filler in the range, while after improving
Treatment effeciency of the phase to gardens sewage.
Further setting：Gas-water ratio is 1 in the pond the contact precipitation-BAF:4~2:1, hydraulic loading is 1 ~ 2m3/m2·h。
So set, on the one hand effectively improving biofilm formation in the range, while the later period is improved to gardens sewage
Treatment effeciency has the effect of good denitrogenation and removal turbidity.
By using above-mentioned technical proposal, the present invention compares compared with the prior art, has the following advantages that：
1, by sewage collecting pool, preparatory preliminary treatment and collection is carried out, suspended matter and bulky grain sundries are filtered；
2, it is closed by activated sludge area in combined multi-stage biological reaction pool and contact biological oxidation district's groups, recycles longitudinal baffle
With horizontal perforated plate, several processing units are classified as, make its gardens sewage is S-shaped successively to flow in each processing unit
It is handled, is conducive to the selection and active holding of dominant bacteria, guarantees the effluent quality of regenerative system；
3, the pond contact precipitation-BAF organically combines contact precipitation and BAF, and operation operation has both contact precipitation and the technique of BAF is special
Sign has the treatment effect improved to fine particle in sewage, microorganism, harmful substance and peculiar smell, improves its gardens sewage
Regeneration, the effect recycled.
