Description
Technical field
The present invention relates to a kind of waste water treatment process, particularly a kind of epoxy soybean oil waste water handling process.
Background technology
Mainly containing oils, hydrogen peroxide, formic acid and fatty acid methyl ester etc. in epoxy soybean oil waste water, acid strong, organic matter is dense
Degree is high, with strong oxidizing property, raw water COD may be up to 20000mg/L, pH1 ~ 2, traditional processing mode be oil removal-materializing strategy-
Just heavy-hydrolysis acidification-aeration-two is heavy-discharge, due to being provided with hydrolysis acidification pool, substantially increase construction cost, and run
Risk.
The content of the invention
Present invention solves the technical problem that be to provide it is a kind of can make the setting of reduction hydrolysis acidification pool, construction can be greatly reduced
The epoxy soybean oil waste water handling process of the security risk coefficient in cost, and operation.
In order to solve the above technical problems, the technical scheme is that：
A kind of epoxy soybean oil waste water handling process, its innovative point is：Oil removal, materializing strategy are sequentially passed through, just sunk, connect
Oxidation, the two heavy, wastewater treatments that discharge completes epoxidized soybean oil are touched, it is comprised the following steps that：
1）Oil removal：In epoxy wastewater add vacuum condensation liquid, the oil slick in epoxy wastewater is separated, epoxidation waste water and
Vacuum condensation liquid is added from the two entrances of oil interceptor, respectively through collecting again after oil removal, carries out mixing, the regulation of water quality；Portion
Sold as product after dividing oil slick purified, part oil slick is processed as discarded object, the oil slick for being not reaching to standard is reclaimed
Purify again, the oil slick for reaching standard is recovered, and produce waste gas to emission-control equipment, remaining waste water enters back into reaction
Chi Zhong；
2）Materializing strategy：Ferrous sulfate and liquid caustic soda will be added in waste water in reaction tank, reaction tank bottom passes through air hose
Road is connected with materialization blower fan, removes hydrogen peroxide, and adjusts the pH of waste water to neutrality, produces some sediments；
3）It is just heavy：The sediment that will be produced in precipitation process delivers to sludge concentration tank；
4）Air supporting：Remaining solid impurity in waste water is removed by pressure air-dissolving method, it is dense that solid impurity is discharged into sludge
Contracting pond.
5）Intermediate pool：Waste water and undressed sanitary wastewater after air supporting enter intermediate pool, and being passed through compressed air is carried out
The regulation of water and water quality, mixing.
6）Catalytic oxidation：To in contact-oxidation pool, contact-oxidation pool bottom passes through air duct and life to the waste water of intermediate pool
Wind transmission machine is connected, and the organic matter of waste water is degraded using the microorganism in activated sludge；
7）Two sink：The sediment that second produces is delivered into sludge concentration tank, it is up to standard to ensure water outlet SS；
8）Discharge：To handle well and reach the sewage of discharge standard and discharged.
Further, during the oil removal, the epoxidation waste water speed for being added is 80m3/ d, the vacuum for being added is cold
Lime set speed is 10m3/d。
Further, the materialization blower fan of reaction tank boosts to 5000mmpa in the materializing strategy.
Further, the materialization blower fan of intermediate pool boosts to 5000mmpa during the catalytic oxidation, catalytic oxidation
Biochemical blower fan boosts to 6000mmpa, and the speed of the sanitary sewage in intermediate pool is 3m3/d。
The advantage of the invention is that：
Most of oily substances of the epoxy soybean oil waste water in it effectively can remove waste water after two grades of oil removals；Then
Hydrogen peroxide is removed through Fenton advanced oxidations again, at this moment the COD in waste water eliminates 80% ~ 90% substantially.Add liquid caustic soda regulation
To neutrality, pH6 ~ 8 or so enter flocculation basin to pH, add PAM to remove insoluble matter through just heavy again, and air supporting removes a small amount of suspended material
After being adjusted through air stirring into intermediate pool and sanitary sewage, waste water now has been equipped with biochemical condition（COD about 1800
Mg/L, pH are 7 or so）, then to contact-oxidation pool, the discharge after two heavy precipitating sludges after biochemical treatment, drainage index is accorded with pump
Close《GB8978-1996 integrated wastewater discharge standards》With《CJ343-2010 sewage enters town sewer water standard》.
