Description

Wastewater from vitamin C production advanced treatment apparatus
Technical field
This utility model relates to technical field of sewage, specifically, relates to processing for through traditional wastewater device After still can not the deep treatment method of sewage of qualified discharge, particular for the vitamin C processed through traditional wastewater device Produce waste water and process to reach the advanced treatment method for sewage water of discharge standard further.
Technical background
Traditional sewage-treatment plant is typically based on activated sludge process.The kind of microorganism and work in activated sludge process Property is restricted, thus some Organic substances are difficult to be degraded, and affect treatment effect.Traditional wastewater treatment technology is generally being difficult to The Organic substance degraded by activated sludge is referred to as " hardly degraded organic substance " or can not biochemical Organic substance.For the city containing industrial wastewater Political affairs sewage, or for industrial wastewater, larger amount of " hardly degraded organic substance " can be remained by traditional sewage disposal, it is difficult to reach Discharge standard or follow-up reuse technology requirement.The waste water that production of vitamin C produces has that wastewater flow rate is big, pollution concentration is high, saliferous Amount high, is difficult to reach cities and towns discharge standard with traditional sewage treatment.
Last century, owing to wastewater from vitamin C production is difficult to process the problems such as up to standard, it is the most all of that the U.S. does not closes it Factory.China becomes global production of vitamin C center at present.Common wastewater from vitamin C production chemical oxygen consumption (COC) (COD) at more than 10000mg/L.COD, through strong process, can be reduced to below 500mg/L, reach by manufacturing enterprise Industrial undertaking is discharged into the standard of municipal sewage plant.But, these remaining COD almost all are " hardly degraded organic substances ", The highest nitrogen pollutant, high rigidity and the salinity more than 1%, feels simply helpless in traditional municipal sewage plant. There is expert it is thought that mankind's sewage treatment area " world-famous puzzle " that face.By up to standard for this kind of commercial production sewage disposal will be The big problem of the numerous similar enterprises final and decisive juncture of China, needs to develop advanced treatment of wastewater technology on the basis of traditional wastewater processes With method (Acute Waste Water Treatment, AWWT).
Advanced treatment of wastewater (AWWT) technology refers to the " difficulty in the sewage after traditional wastewater processes containing higher concentration Degradation of organic substances ", need the sewage disposal technology used when processing further.The application that advanced treatment of wastewater technology is main Including: after (1) conventional process, sewage can not reach discharge standard, needs advanced treating (including proposing mark transformation);(2) tradition After method process, sewage can not meet the inflow requirement of reuse technology, needs advanced treating;(3) in order to make the tail water of reuse technology Emission request can be reached, sewage or reuse technology tail water are implemented advanced treating.
Common advanced treatment of wastewater technology includes multiple method.The most common Fenton reagent method is a kind of chemistry side Method, consumes substantial amounts of chemicals, produces substantial amounts of chemical sludge, and operating cost is high.Due to Fenton reagent method mainly with flocculation The mode of precipitation removes pollutant, therefore preferable to the Pollutant Treatment effect of relatively macromole, and the pollutant to less molecule, Treatment effect is limited.Membrane bioreactor (MBR) can also as a kind of advanced treatment of wastewater method, but due to MBR method still So with activated sludge as core, reduce the limited space of " hardly degraded organic substance " further.Biomembrane biochemistry advanced treatment of wastewater Biochemical method (Oxidation Enhanced Bio-is strengthened in method (Bio-Film Bio-reaction, BFB) and oxidation Reaction, OEB) substantial amounts of chemical sludge will not be produced, run power consumption low, be the method for relatively environmental protection.
It is true that whether organic pollutant can be relevant with microbe species and population composition by biochemical degradation, if energy Enough cultivate more horn of plenty and microbial population targetedly, the Organic substance of some conventional method " difficult degradation " is possible to become For " degradable " Organic substance.Therefore for cultivate more horn of plenty microorganism and create conditions be eliminate " hardly degraded organic substance " direction it One.
Chinese patent " composite biological packing and bioreactor thereof " (201020204406.9) discloses a kind of composite gap Biologic packing material (Multi-Cavity MEdia, MCM), including a netted shell of hard and be filled in this shell two kinds with On medium block.Owing to having bigger space between shell, between medium block, there is less space, in medium block, have micro-interstices; Mixing wastewater with air give-and-take conditions marked difference in big space, little space and microvoid causes the marked difference of dissolved oxygen, permissible Realize aerobic, the coupling on the spot of anoxia, anaerobism.Typical media block combination simultaneously is to have the coke briquette of micropore or charcoal lump and fire The combination of mountain rock, the feature of this combination is coke briquette or charcoal lump has a relatively low redox potential, and the oxidation in volcanic rock Ferrous components has higher redox potential, and different microorganisms can select different dielectric surfaces to perch.
Chinese patent (200710195135.8) discloses a kind of biofilm reactor, wherein uses MCM first to realize Oxygen, anoxia, the coupling on the spot of anaerobism.Under air stripping recycle stream effect, in this reactor, realize multistage aerobic, anoxia again, detest Coupling in oxygen reactor.Above biofilm reactor technology to cultivate more horn of plenty and targetedly microbial population with fall Solve " hardly degraded organic substance " and provide technical foundation.Simultaneously because the existence of multiple-microorganism so that synchronize digestion/denitrification with Synchronous degradation residue biological sludge is achieved.
But when similar techniques is used for the pollutant of more difficult degradation, the process especially for vitamin C tail water is, single One method is also not enough so that sewage disposal is up to standard, needs many secondary coupling of multiple bioprocesses.
Through the biomembrane biochemistry advanced treatment of wastewater of many secondary coupling, part " hardly degraded organic substance " is still had to be difficult to be given birth to Change degraded.Strong oxidizer can be used to aoxidize these " hardly degraded organic substances ", change its chemical property, improving it can be biochemical Property, carry out biochemical treatment the most again.This process can be referred to as the biochemical reaction (OEB) that oxidation is strengthened.
