Abstract
The invention discloses a wastewater treatment method. The wastewater treatment requires the following devices and facilities: a submersible sewage pump, a preaerator, an ultraviolet disinfection device, a DN200 sludge pipe, a manual butterfly valve, an electric butterfly valve, a regulating tank, a disinfecting tank, a grit chamber and a clean water tank. The water treatment method comprises the following steps: (1) industrial wastewater discharged by respective workshops is introduced into a grid well through a pipeline, flows into an oil separator after most eel viscus fragments are removed by the grid well and flows into the regulating tank after grease is removed. The quality of the effluent water treated with the technical proposal meets the first grade standard of Integrated Wastewater Discharge Standard.
Description
Technical field
The present invention relates to eel hanging culture field, be specifically related to a kind of method of wastewater treatment.
Background technology
At present, existing eel hanging culture waste water processing station adopts primary sedimentation art breading waste water, treatment effect is unstable, be badly in need of transformation, the existing settling tank of eel hanging culture waste water processing station one, only eel hanging culture waste water to be carried out after simple precipitation reuse and eel hanging culture again, but in actual use procedure, find that settling tank treatment effect is not good, can not ensure the water quality of eel hanging culture.
Summary of the invention
The object of the present invention is to provide a kind of method of wastewater treatment, solve above-mentioned multinomial defect.
The technical problem that the present invention solves can realize by the following technical solutions: a kind of method of wastewater treatment, and equipment and the facility of the use of described wastewater treatment needs are as follows: submersible sewage pump, preaerator, apparatus for ultraviolet disinfection, DN200 shore pipe, Hand-operated butterfly valve, electric butterfly valve, equalizing tank, sterilization pool, settling pit and clean water basin.
Preferably, described method of wastewater treatment comprises the following steps:
(1) factory effluent introduces grille well through pipeline after respective workshop is discharged, and removes after most of eel internal organ fragment flow into oil trap through grille well, enters equalizing tank after removing grease.
(2) then directly enter one-level, secondary anaerobic pond by water pump lifting, the larger molecular organics in one-level, secondary anaerobic pond waste water is degraded to small organic molecule, and waste water enters preaeration tank subsequently.
(3) waste water flows to one-level biological contact oxidation pond through overflow weir after preaeration tank.
(4) waste water continues to flow to secondary biochemical pond.
(5) waste water flows to tube settler and sand filter through overflow weir after I and II biochemical treatment.
(6) last, the draining penetration depth treatment system after second-stage treatment, in advanced treatment system, sewage enters reuse pool after coagulating sedimentation and sterilization pool.
Preferably, in described step (3) and step (4), described one-level biological contact oxidation pond secondary biochemical pond and bottom are all provided with microporous aeration device, are provided with biologic packing material in described microporous aeration device.
Preferably, in described step (4), in described secondary biochemical pond, add appropriate BOD.
Beneficial effect: the present invention carries out wastewater treatment by adopting the mode of equalizing tank+sterilization+precipitation, eel hanging culture waste water passes through to enter equalizing tank into people's water channel road and carries out runoff investigation, enter sterilization pool again, after sterilization, water outlet enters settling pit, enter clean water basin after desilting process, then be back to the hanging culture of eel; Effluent quality after the technical program process reaches the primary standard in " integrated wastewater discharge standard ", reaches technique and the product water supply standard of " urban sewage reutilization industry water standard " through wastewater deep treatment process processed waste water.
Embodiment
The technique means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
A kind of method of wastewater treatment, equipment and the facility of the use of described wastewater treatment needs are as follows: submersible sewage pump, preaerator, apparatus for ultraviolet disinfection, DN200 shore pipe, Hand-operated butterfly valve, electric butterfly valve, equalizing tank, sterilization pool, settling pit and clean water basin, described method of wastewater treatment comprises the following steps: (1) factory effluent introduces grille well through pipeline after respective workshop is discharged, remove after most of eel internal organ fragment through grille well and flow into oil trap, after removing grease, enter equalizing tank.(2) then directly enter one-level, secondary anaerobic pond by water pump lifting, the larger molecular organics in one-level, secondary anaerobic pond waste water is degraded to small organic molecule, and waste water enters preaeration tank subsequently.(3) waste water flows to one-level biological contact oxidation pond through overflow weir after preaeration tank.(4) waste water continues to flow to secondary biochemical pond.(5) waste water flows to tube settler and sand filter through overflow weir after I and II biochemical treatment.(6) last, draining penetration depth treatment system after second-stage treatment, in advanced treatment system, sewage enters reuse pool after coagulating sedimentation and sterilization pool, in described step (3) and step (4), described one-level biological contact oxidation pond secondary biochemical pond and bottom are all provided with microporous aeration device, be provided with biologic packing material in described microporous aeration device, in described step (4), in described secondary biochemical pond, add appropriate BOD.
Based on the design of above-mentioned method of wastewater treatment, the present invention carries out wastewater treatment by adopting the mode of equalizing tank+sterilization+precipitation, eel hanging culture waste water passes through to enter equalizing tank into people's water channel road and carries out runoff investigation, enter sterilization pool again, after sterilization, water outlet enters settling pit, enter clean water basin after desilting process, then be back to the hanging culture of eel; Effluent quality after the technical program process reaches the primary standard in " integrated wastewater discharge standard ", reaches technique and the product water supply standard of " urban sewage reutilization industry water standard " through wastewater deep treatment process processed waste water.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
