Description

A kind of AMBR-MABR-A/O-MBR side for handling high-enriched organics and ammonia nitrogen waste water Method and its equipment
Technical field
The invention belongs to sewage disposal disposal technology field, more particularly to a kind of processing high-enriched organics and ammonia nitrogen waste water AMBR-MABR-A/O-MBR methods and its equipment.
Background technology
High-enriched organics and the dyeing waste water and food of ammonia nitrogen waste water such as pharmaceutical intermediate wastewater, textile industry production discharge The fermentation of product processing industry discharge and cleaning fluid etc., it is characterized in that complicated component, COD, BOD, ammonia nitrogen, suspension content are high, and And easily accumulate in the environment, there is toxic action to biology, human health is constituted a serious threat.With China industrialize into The propulsion of journey, discharge food processing, weaving, pharmacy, papermaking, coking and PETROLEUM PROCESSING of high-enriched organics and ammonia nitrogen waste water etc. Industry has obtained high speed development, and corresponding wastewater discharge increases, and further increases the environmental pressure of major water system.
The method of common processing high concentrated organic wastewater substantially has batch-type(Intermittently)Activated sludge process (SBR), A/O- MBR、A2/ O etc., the new reactor developed in recent years have AMBR, ABR-MBR etc., and ABR and AMBR can handle influent load height Up to 8.0kg COD (m3·d)-1, COD clearances are up to 90%, but still do not reach《Urban sewage reutilization urban reclaimed water Water quality》In (GB/T 18920-2002) relevant regulations determine design effluent quality, and the clearance of ammonia nitrogen and total phosphorus compared with It is low.A/O-MBR and A2The concentration of/O PROCESS FOR TREATMENT waste water is 200-3000mg/L, and can effectively remove ammonia nitrogen, total phosphorus, is made Removal standard can be reached by obtaining high concentrated organic wastewater.AMBR-A/O-MBR group technologies can effectively compensate for AMBR and A/O- Weak points of the MBR in sewage disposal.
AMBR is U.S. Iowa university, and Dague and Angenen are taught in nineteen ninety-five in research UASB and two kinds of ASBR A kind of Novel anaerobic technique developed on the basis of reactor.AMBR aerogenesis after improvement can respectively be collected, can reduce bottom Thing short-circuit cycle, and flow to timing and change and can bear higher organic loading and (reach as high as 42-45 kg (m3·d)-1)。 AMBR can also realize the continuous migration of sludge, and the volatile fatty acid (VFA) in first cell compartment can be made to maintain reduced levels, pH Close to neutrality.AMBR can just reach preferable effluent quality, and stable fortune under suitable conditions, by short period of time OK, quick start is realized.
The method for removing ammonia nitrogen mainly has traditional nitration denitrification, short-cut nitrification and denitrification, three kinds of simultaneous nitrification and denitrification nitre.Pass Nitration denitrification of uniting is that the organonitrogen compound in waste water is converted into NH by heterotrophic microorganism in anaerobic environment4 +- N, then certainly Support nitrococcus and nitrifier in aerobic environment by nitrification by NH4 +- N is further converted to NO2 -- N or NO3 -- N, tightly Then denitrifying bacterium passes through denitrification by NO in anaerobic environment in system2 -- N or NO3 -- N switchs to N2, to realize wastewater biological Denitrogenation, such as A/O-MBR techniques.The key that short-cut nitrification and denitrification technology is successfully realized is to control nitration reaction and maintain Asia Nitric acid salt phase, without the conversion of nitrite to nitrate, directly carry out denitrification.Synchronous nitration and denitrification is due to oxygen The limitation of diffusion, produced in microorganism flco or biomembrane and dissolve oxygen gradient, the outer surface of microorganism flco or biomembrane is molten It is higher to solve oxygen, based on aerobic nitrification bacterium and ammonifiers;To go deep into inside flco, oxygen transmission is obstructed and a large amount of consumption of external oxygen, Anoxic zone is produced, denitrifying bacterium is dominant, so as to form the microenvironment for being advantageously implemented synchronous nitration and denitrification, such as membrane bioreaction Answer device(MABR)Technique.
The carrier that membrane bioreactor grows Breathable filmses as microorganism, it is that a kind of gas permeability using film is attachment The new technology that microorganism on surface supplies oxygen.Membrane module both passage as oxygen transfer, the again carrier as microorganism attachment.By The reverse mass transfer of pollutant, oxygen concentration gradients are internally formed in biomembrane in oxygen and liquid phase, so as to realize single anti- The condition that aerobic zone and anaerobic zone coexist inside device is answered, realizes that simultaneous nitrification and denitrification reacts.
A/O-MBR techniques are a study hotspots in recent years, in processing sanitary sewage(COD:200-1500mg/L, ammonia Nitrogen:20-60 mg/L), pig biogas slurry waste water(The COD for being derived from the UASB water outlets of certain Large-scale pig farm is 800-3500mg/L, Ammonia nitrogen is 400-1200mg/L,)Research is respectively provided with terms of etc. a variety of sewage types, the technique is to CODCrClearance more than 60%, Crown_interception of the film to microorganism in MBR techniques so that nitrifier not easily runs off, and can constantly grow enrichment, therefore MBR System is fine to the nitrification effect of ammonia nitrogen, but can incrementally accelerate fouling membrane, treatment effect drop with water inlet pollutant concentration It is low.Due to the technique not spoil disposal, therefore MBR does not have removal effect to TP substantially, the TP concentration in water outlet is with entering aqueous phase It is more little than changing.
Publication No. CN203392919U Chinese patent applications disclose a kind of anaerobic baffled migration formula sludge bed reactor. The technique is realized by following technology path:Rectangular housing is divided into alternation and current side by reactor by partition wall To opposite the first reative cell and the second reative cell, each reative cell is set from water inlet, along the trend of partition wall to delivery port Have to form multiple cell compartments of upper and lower baffling, partition wall, which is provided with, connects cell compartment corresponding in the first reative cell and the second reative cell Connected entrance.The reactor can make load more uniform distribution improve the impact resistance of sludge, but handling in different cell compartments Effect in terms of high-concentration ammonia nitrogenous wastewater is poor.
Publication No. CN101913734A Chinese patent applications disclose a kind of A/A-MBR intensified denitrification and dephosphorizations combination unit And its technique.The technique is realized by following technology path:The device includes intake pump, grid, regulating reservoir, anoxic Pond, anaerobic pond, MBR ponds, membrane module, go out water pump, backwashing pump, backwash water tank and air blower.After sewage is lifted by intake pump, Enter regulating reservoir after grid filtration, enter back into anoxic pond and anaerobic pond, finally enter MBR ponds, the water outlet after UF membrane.The work Skill has preferably effect in terms of town sewage is handled, and the organic matter of removal and the concentration of ammonia nitrogen are relatively low, cause organic carbon source It is low, it need to additionally increase carbon source so that cost increase.
