Abstract
The present invention provides a kind of synthetic rubber production sewage treatment method, includes the following steps: that sewage enters reaction coagulation tank by after sewage homogeneous, adds aluminium polychloride and polyacrylamide in reaction coagulation tank；The liquid that step 1 is obtained imports the adsorption tank containing microorganism, imports sedimentation basin, and partial sludge is back to adsorption tank and is adsorbed again, drains into sludge concentration tank outside excess sludge, the supernatant after precipitating enters hydrolysis acidification pool；It is put into the microorganism of absorption particulate matter and colloidal substance in hydrolysis acidification pool, after adsorbing 30min, sanitary sewage is added toward hydrolysis acidification pool, stirs, mixes, precipitating；Liquid after precipitating is separated again, supernatant imports mixed flocculation pond, and the micro- aeration of solid packing is added in mixed flocculation pond.Synthetic rubber production sewage treatment method of the invention, safe and reliable to operation, stable effluent quality invest, realization pollution reduction lower with operating cost, and realistic meaning is great.
Description
Technical field
The invention belongs to a kind of industrial sewage treatment technology, in particular to a kind of synthetic rubber production sewage treatment method.
Background technique
The waste water generated in synthetic rubber production process is a kind of very intractable wastewater from chemical industry.Especially butadiene-styrene rubber
It produces in institute's waste discharge, is difficult to biodegrade organic matter containing a large amount of.Such as benzene homologues, dispersing agent, milk coagulant.Waste water
Middle COD is at concentrations up to 1000~1700mg/l, and salt is in 1800mg/L or more.With existing general chemical industry wastewater treatment method,
Such as level-one air bearing, surface aeration, catalytic oxidation and sand filtration technique, be difficult for COD concentration to be down to discharge standard 100mg/l with
Under, high salt content is also difficult to be removed with commonsense method.The existing mixed processing method defect higher there is also processing cost, no
The more easy to handle Sewage treatment of benefit utilizes.
Summary of the invention
The object of the present invention is to provide a kind of waste-water treating process for synthetic rubber production, will not easy to handle and easy to handle waste water
It handles respectively, reduces the discharge amount of sewage, reduce sewage treatment expense, be conducive to easy to handle wastewater ocean disposal.
The technical scheme is that
A kind of synthetic rubber production sewage treatment method, includes the following steps:
(1) sewage is put into conditioning tank and adjusts pH value, after homogeneous, sewage enters reaction coagulation tank, throws in reaction coagulation tank
Add aluminium polychloride and polyacrylamide；
(2) liquid for obtaining step (1) imports the adsorption tank containing microorganism, adsorbs 30min, then imports sedimentation basin, portion
Divide sludge reflux to be adsorbed again to adsorption tank, drains into sludge concentration tank outside excess sludge, the supernatant after precipitating enters water
Solve acidification pool；
(3) microorganism of absorption particulate matter and colloidal substance is put into hydrolysis acidification pool, after adsorbing 30min, toward hydrolysis acid
Change pond and sanitary sewage is added, stir, mixes, precipitating；
(4) liquid after precipitating is separated again, supernatant imports mixed flocculation pond, adds solid in mixed flocculation pond and fills out
Expect micro- aeration.
Synthetic rubber production sewage treatment method of the invention, the solid packing in the step (4) is PAC, iron charcoal is filled out
The substances such as material.
Synthetic rubber production sewage treatment method of the invention, being separated into enhancement activated carbon in the step (4)
Adsorption tower, by adsorption filtration, centrifugation.
The beneficial effects of the present invention are:
Synthetic rubber production sewage treatment method of the invention, safe and reliable to operation, stable effluent quality, investment and operating cost
It is lower, the sewage generated in production process can be made to reach COD≤60mg/L, NH3- N≤5mg/L water quality objective is realized dirty
Object emission reduction is contaminated, realistic meaning is great.
Specific embodiment
A kind of synthetic rubber production sewage treatment method, includes the following steps:
(1) sewage is put into conditioning tank and adjusts pH value, after homogeneous, sewage enters reaction coagulation tank, throws in reaction coagulation tank
Add aluminium polychloride and polyacrylamide；
(2) liquid for obtaining step (1) imports the adsorption tank containing microorganism, adsorbs 30min, then imports sedimentation basin, portion
Divide sludge reflux to be adsorbed again to adsorption tank, drains into sludge concentration tank outside excess sludge, the supernatant after precipitating enters water
Solve acidification pool；
(3) microorganism of absorption particulate matter and colloidal substance is put into hydrolysis acidification pool, after adsorbing 30min, toward hydrolysis acid
Change pond and sanitary sewage is added, stir, mixes, precipitating；
(4) liquid after precipitating is separated again, supernatant imports mixed flocculation pond, adds solid in mixed flocculation pond and fills out
Expect micro- aeration.
Synthetic rubber production sewage treatment method of the invention, the solid packing in the step (4) is PAC, iron charcoal is filled out
The substances such as material.
Synthetic rubber production sewage treatment method of the invention, being separated into enhancement activated carbon in the step (4)
Adsorption tower, by adsorption filtration, centrifugation.
Invention can be further appreciated that by the embodiment of the present invention given above, and above embodiments are only of the invention several
Specific embodiment, but design of the invention is not limited thereto, it is all to be made a non-material change to the present invention using this design,
It should all belong to behavior that violates the scope of protection of the present invention.
