Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that
It is used to help understand the utility model for the explanation of these implementation methods, but does not constitute to restriction of the present utility model.This
Outward, as long as technical characteristic involved in the utility model disclosed below each implementation method does not constitute conflict each other
Can just be mutually combined.
A kind of bio-contact oxidation sewage disposal system, including pass sequentially through filtering ponds, regulating reservoir, the dosing of pipeline connection
Reaction tank, preliminary sedimentation tank, hydrolysis acidification pool, contact-oxidation pool, second pond.First, sewage enters filtering ponds by water inlet, filtering
Pond is internally provided with grid, is used to remove soft twister, larger solid particle debris and drift in sewage, so that after protecting
Continuous work water pump service life simultaneously reduces system treatment live load.Regulating reservoir is provided with submersible sewage pump, dividing plate and current boosting
Device, dividing plate is vertical with regulating reservoir bottom of pond after installation to be square, and can prevent sewage in pond internal short-circuit, and passes through to set latent dirt
Pump can be by the tear of the materials such as sewage medium-length fibre, bag, band, grass, cloth, cut-out, and then smooth discharge, further reduces follow-up water
The load of matter treatment, and being provided with beneficial to effluent cycle is made for current boost motor, make it homogenize.Sewage after the completion for the treatment of leads to
Cross elevator pump and be promoted to dosing reaction tank, the main effect of dosing reaction tank is to make SS, COD therein anti-by chemical agent
Should wait to form alumina blossom particles thing, dosing reaction tank is internally provided with agitator, and is provided through outside it in dosing reaction tank
The dispensing pipeline in portion, dispensing pipeline is connected by measuring pump with filling pocket pipeline.When need to add medicament, it is only necessary in filling pocket
Liquid is configured, measuring pump has been then turned on and is calculated input amount.After in flocculation sediment in dosing reaction tank, the sewage is then hydrolyzed
Acidification pool, is dissolved organic matter by insoluble hydrolysis of organic matter, and the macromolecular substances of difficult for biological degradation are converted into easy biology
The small-molecule substance of degraded.Two of hydrolysis acidification pool most basic effects are：One is to improve wastewater biodegradability, and macromolecular is had
Machine thing is converted into small molecule；Two is to remove the COD in waste water, partial organic substances degraded synthesis own cells.In this implementation, hydrolysis
The structure of acidification pool is consistent with the structure of contact-oxidation pool, is disposed with sludge outlet, water inlet, cloth inside it from the bottom to top
Device of air, packing layer and delivery port, but its running differs, and hydrolysis acidification belongs to half anaerobic digestion process, includes
Two processes of hydrolysis and acidifying, wherein acidifying belongs to the process of anaerobic digestion, but its target for being pursued with complete anaerobic digestion
Difference, its object is to non-dissolved organic matter in raw water is changed into dissolved organic matter, so as to contribute to the aerobic of later stage
Biological treatment, i.e. contact-oxidation pool.And in order to improve the effect for the treatment of, can be by inside hydrolysis acidification pool or/and contact-oxidation pool
Packing layer be arranged to filler upper strata and filler lower floor, wherein, filler lower floor be located at filler upper strata lower section, filling out in filler lower floor
Material is using the larger filler in aperture, and the filler on filler upper strata uses the less filler in aperture, and it is soft that filler may be selected from suspension type
One kind in filler, suspension Ball-type packing, half suspension Ball-type packing, polyhedron empty ball filler, or by various different fillers
Combination, forms combined stuffing, by the setting of the filling-material structure, otherwise can prevent that upper filler aperture setting is unreasonable causes stuffing hole
Block, otherwise the excessive effluent quality for causing in filler aperture is poor.Filler upper strata or filler lower floor are by the suspension of correspondence position
The filler that support is fixed and be fixed on suspension holdfast is formed, and suspension holdfast can be formed by connecting by common plastic tube.Cloth
Being provided with for device of air is beneficial to make sewage generation vortex flow, vortex flow to realize being stirred floc sludge or granule sludge
